Puleggia cooper s - modus operandi
METODO SENZA SMONTARE IL COMPRESSORE
Time Required
1-3 hours
Tools Required
1/4" ratchet
3/8" ratchet
#25 torx
standard screwdriver
phillips screwdriver
8mm socket or #30 torx (changed in late '03) if an aftermarket intake is installed
10mm socket
13mm socket
16mm socket
18mm deep socket or wrench
clamp removal tool or small standard screwdriver and small plier
belt tensioner tool (or small screwdriver to pin the tension)
pulley removal tool with crow's foot puller (Harmonic Balancer puller)
2 floor jacks and 2 short stands
It also helps to have ratcheting wrenches in 10mm and 16m sizes for the tensioner, but it isn't a requirement.
Before starting, open the rear hatch and disconnect the battery with a 13mm. Leave the hatch open.
1. Jack up the car until the stand will fit under the factory jack point without any extension (to keep the car relatively low).
2. Remove the intake. Start by removing the battery terminal from the side of the airbox - it just clips out.
If you have the Rogue/Madness/Turner intake (one in the same), remove the 8mm bolt from the partition. The Alta is similar, except that you will be removing both bolts, top and bottom.
Remove the clamp at the intake boot.
Remove the two #25 torx bolts at the base of the intake heat shield (or if it is the stock box, these same two bolts hold the top of the airbox in place).
Remove the intake or the panel filter and airbox top (depending on what you have).
3. Remove the ECU and lower airbox half. Remove the ECU cover (it just has two tabs on each side that squeeze together and pull off), then remove each of the two plugs. These are a little tricky - they have tabs on the end of the plug that pull away from the plug which forces the plug up and off. It's easiest to use a small screwdriver very carefully to pull these tabs away from the plug.
You can see the tab just under my left hand on the larger of the two plugs.
Remove the 10mm bolt that holds the driver side of the airbox down. There is also a small steel bracket holding a wiring loom that is attached with this same 10mm. You will need to move this loom slightly out of the way to remove the airbox.
Now remove the clamp on the snorkle to the airbox. You will either use a standard screwdriver if you have replaced the clamp, or the factory removal tool if you still have the stock clamp (you can also remove the stock clamp with a small screwdriver and replace it with the screwdriver and small pliers). Press down on the tab inside the bottom of the airbox that holds the snorkle in place and pull it out of the car.
Remove the wiring to the battery terminal from the lower airbox half.
You can now remove the lower airbox half by pulling back and then out.
Here's what it looks like with the box removed. Note the two small rubber mounting bolts at the bottom rear of the partition. The box is molded on the underside to fit into these mounts, which is why you had to pull toward the front of the car before you pulled up and out.
4. Remove the skid plate. There are two phillips head screws, one on each side (they are like dzus fasteners).
Then, remove the three 10mm bolts in front of the lip.
Now you can pull the skid plate out by tugging aft then down.
5. Remove the lower motor mount 16mm bolt.
6. Using a small block of wood, line up the jack with the power steering fan under the drainplug. Being very careful not to interfere with the power steering fan, jack up until you are resting the jack firmly on the motor. Place a second jack under the ridge in the gearbox. The second jack is not necessary, but it helps with the lateral alignment of the driver side motor mount bolt during reinstallation.
7. Remove the driver side 16mm motor mount bolt. It helps to wiggle as you are pulling it out, and jacking slightly may help as well. It is a little bit of an art, but once you get the hang of it, it is pretty easy (and it is the same thing threading it back in - you get good at it by just wiggling and jacking the motor at the same time).
8. Remove the 10mm clamp bolt holding the wiring loom and radiator hose to the intake manifold.
9. Remove the 13mm ground bolt from the passenger side motor mount.
Be careful to hold the bottom of the bolt to prevent it from falling out when you pull the nut off.
10. I slide the regulator off its bracket to gain more room for the tensioner tool, but you don't really have to. Remove the quick disconnect fittings and use a screwdriver to push the tab on the bracket in slightly and slide it off toward you.
11. There are three hoses attached to the vibration damper bracket. These just pop out of their respective holders.
12. Remove the vibration damper bracket 16mm bolts - the front one is shorter than the rear (for reassembly).
Remove the damper bracket.
NOTE FOR mid 2004 AND LATER CARS: THE MOTOR MOUNT HAS CHANGED, AND THIS STEP IS NOT NECESSARY, AS THE MOTOR MOUNT IS ALL ONE PIECE ON THESE CARS.
13. Using the 18mm wrench or deep socket, remove the passenger side motor mount nut.
14. Now, being very careful in several places, slowly jack up the motor. Pay special attention to the coil pack plug, the throttle body, and the power steering fan. Watch all of the hoses and wiring as you go up incrementally. This is the riskiest part of the job, so pay very close attention.
15. Using the belt tensioner tool, remove the tension on the belt and pull the serpentine belt off of the idler gear. The pulley tool is just a big lever with a pin on the end that fits into the two holes in the tensioner itself. The lever fulcrum is the forward 16mm tensioner mounting bolt.
No making fun of those welds! That's what happens when you run out of inert gas and at the same time don't prep your surface!
You can also remove the tension on the belt by prying the tensioner up and placing a pin in the center of the spring as it compresses to hold it in place. This will become obvious as you do it. It helps to pry on a 16mm socket placed on the forward bolt of the tensioner (used as a fulcrum).
16. Remove the belt tensioner. There are four bolts, two 10mm and two 16mm.
The rear 16mm is the whiter of those two bolts in the fuzzy pic.
Note the two holes where the tensioner tool is inserted.
Now you have access to the pulley!
17. Install the pulley removal tool. Start by taking the plastic center cap out of the s/c shaft. It helps to get the lip out slightly with the blade of a standard screwdriver, then it will just thread right out like a bolt by hand.
Install a 13mm head bolt into the center of the shaft. Slide the two halves of the removal tool over the pulley and tighten the allens.
Now install the crow's foot puller onto the removal tool.
Using a ratchet on the end of the puller, wind the pulley off. This is a very effective and easy way to get the pulley off. It requires no drilling or cutting, and has worked every time without a hitch.
18. This depends on which pulley you are using.
For the PROMINI or Helix: It's time to either get out the torch, or go get the pulley hub out of the oven (use 450F or so). Heat the hub using the torch for about 10 seconds, then slide the hub onto the shaft with a hot glove, making sure it is flush with the end of the shaft. Using a screwdriver or spacer helps make sure it doesn't go too far onto the shaft.
Using a drop of red Loctite on each bolt, install the aluminum half of the pulley. It may be easier to have the bolts snug, and then check them again after you get the tensioner and belt back on.
For the Alta or RSpeed: Take the hub center and slide it ALL THE WAY ONTO THE SHAFT. Then place the pulley over it until it stops making sure to keep the bolt holes aligned. Now use a drop of red Loctite on the bolts and torque them in a cross pattern.
19. Reinstall the tensioner with the two 16mm and two 10mm bolts. After you have it installed, replace the belt (you will again have to use the tensioner tool to release the tension while you get the belt back on). Here is a rough diagram of the serpentine belt routing:
Here is the tensioner being installed:
20. Slowly lower the car onto the passenger side motor mount bolt. Once you get the nut started, place a stand with wood under the gearbox and slide the jack more to the center of the motor/gearbox. Now jack it up slightly and use the wiggle jack method to get the other motor mount bolt started. After that, it's just a matter of reinstalling everything.
21. Reinstall the vibration damper bracket (two 16mm bolts - long bolt to the rear of the car) and the associated hoses by snapping them back into place.
22. Reinstall the regulator and quick disconnect hoses.
23. Reintall the 13mm ground strap bolt.
24. Reinstall the 10mm hose/wire loom clamp bolt.
25. Reinstall the airbox. When you are putting in the lower half of the airbox, make sure you lower it into position before sliding it back into the rubber mounts. It helps to take a look at the underside and figure out how the rubber mounts fit into the bottom of the airbox. You can feel the box and rubber mounts to be sure they are attached.
You use the tabs on the ECU plugs to reattach them. Make sure they are fully extended, line them up on the associated plug, then slowly close the tab and it will pull the plug onto the ECU. Replace the ECU cover by pressing it into place.
Reattach the 10mm forward bolt on the airbox - don't forget to put the bolt through the wiring loom bracket too. Reattach the snorkle by presing it into the lower airbox half and lining up the pin on the snorkle with the female receptacle. Reatach the snorkle hose clamp.
Replace the intake with the 8mm and #25 torx bolts. Don't forget to reattach the intake rubber boot and snug the clamp.
26. Reattach the 16mm lower motor mount bolt.
27. Put the skid plate back in place with the three 10mm bolts and the two dzus type fasteners (phillips head).
28. Remove the jack stands and lower the car.
29. Reattach the battery terminal.
30. Turn the ingnition key on for 10 seconds to reinitialize, then start the car. Check to see that nothing is askew (I like that word). Listen for belt noises, look at the belt alignment, check for any leaks, etc.
Go out and enjoy your new monster!

This is not a job for the faint of heart!
Turn your oven on at 500F. Put the new pulley hub in the oven while you are working on the car. Put only the steel part of the pulley in.
Start by jacking up the front of the car and using jack stands. Remove the front wheels.
Remove the intercooler plastic cover with #25 torx. These also mount the intercooler. Here's a shot of those bolts and the cover:
Now remove the fuel rail. Remove the wiring harness on each injector. The fuel lines are all quick release - very nice. Here is the fuel rail:
Remove this by just using the quick release on each line and pulling the wires.
Now take off the fuel line - the black one in the center front of the fuel rail. Again, it's just a quick release fitting. Once you get it off, tie wrap it to the bonnet hinge on the passenger side to get it out of the way and keep fuel from spilling everywhere.
The fuel rail is held on with 13mm nuts - remove those. There is a vaccuum line under the rail that needs to be removed also (don't forget to put this back on!).
Now pull the rail out - it pops off.
The front bumper needs to come off too. This isn't as bad as it sounds, honest! Pull the #30 torx from the front.
Pull the 10mm and phillips head screws under the front spoiler.
The wheel well has a series of phillips heads. The passenger side comes all the way out, so pull all of them. The driver side doesn't need to be pulled, so just take out the forward ones on that side. In the forward part of the wheel well, there is a 10mm that holds the bumper on on each side. It is oriented up and down.
Under the car, there are 2 torx on each side that hold the bumper brackets. You can undo them as well.
Now pull the bumper off, and as you do, disconnect the wiring harnesses for the lights in the bumper - they squeeze together on the body side and then pull off - another quick disconnect fitting.
Once you have the bumper off, pull the aluminum energy absorber off by removing the 13mm nuts. Now you're down to the radiator.
Here's the bumper bracket, the bumper, and the energy absorber:
Now start on the intake. Remove the "snorkle" clamp and pull the intake boot off.
While you're there, remove the intake hose also.
The intake is held in place with a series of 13mm bolts. It helps to have a magnet to remove these.
Remove the valve cover breather. It is yet another quick disconnect - push down on the red tab and the line just pulls right out.
Now pull the intake out.
Pull the water hoses. You will need to put the drain pan under the car and have some rags ready. This is where the Snap-on tool comes in. Remove the water pump hose first.
Then remove the radiator hose. After pulling the mounting nuts, the radiator will swing down out of the way. Leave the a/c compressor lines attached.
On the front of the car, you can see the intake (black plastic) to the supercharger. This has a "safety bolt" (13mm). Once you remove the bolt, it can come out with the intake. Undo the clamp to the air filter. Pull the wiring harness on the throttle body to take it out as one piece. Be careful with the green gasket on the supercharger. Inspect it carefully, as there have been issues with cracked gaskets on the S.
There are also two quick release lines, a black and a grey, on the intake to the supercharger.
Now the fun part! We finally get to pull the supercharger. Put the tensioner tool on the 16mm supercharger mount bolt on the passenger side and line up the two holes on the tensioner with the two pins on the tool. Now pull to release the tension and remove the belt.
Here's the belt popped off:
Now pull the bolts securing the supercharger - some are ten, some are 13, and one is 16mm.
Now pull the water pump mount bolts.
Pull the water pump off of the supercharger. Here it is out of the car:
This is a shot with the water pump off. The flange for the water pump on the case is clearly visible here. Pull it off and replace the o-ring. This is another problem spot on the S, and while you're here, you might as well get it. The o-ring is available at the dealer. There is one on the water pump itself as well.
Here is the 16mm mount bolt. This is also the one the tensioner tool is placed over.
The supercharger succumbs!!!! Very Happy
Here is as far as you tear down the motor for this install. Note that the block is the same on the Cooper.
The end of the pulley shaft has a plug. You can remove this with the method shown here:
Once it is removed, there are threads for a 13mm bolt that will be used later.
Now install the pulley removal tool.
Here's a picture of the supercharger compressor blades and the pulley removal tool installed:
Now that the tool is installed, place that 13mm bolt in the threads on the shaft. Install a gear puller on the removal tool using a pointed chuck on the center of the bolt. Then just crank off the pulley. It took a lot less than I thought it would.
Here is the bare supercharger shaft. There are no keys or anything else on the shaft - it is a pure interference fit. You can still see the bolt used with the gear puller
Lube the pulley shaft with some high temp bearing grease. Take the hub out of the oven with a welder's glove or hot glove and SLIDE it onto the shaft. Avoid banging the supercharger shaft at all costs. Make sure the hub is oriented correctly for the pulley to go on. Push the hub on until it is flush with the end of the shaft.
Here is the installed hub:
put the pulley on the hub with the supplied allens using some loctite.
You can barely see the new pulley and the allens under the black hose in this shot:
Now start the reassembly process.
Put the front bumper back on. Make sure to check all of the wiring harness connections on the intake, the fuel rail, the fuel regulator (the black piece at the passenger side of the fuel rail), and the lighting.
Fill the coolant system and flush the air with the bleeder on the radiator through the reservoir tank.
When you turn the car on, let it sit for ten seconds in the on position before starting it. That resets the throttle.
Start the car and look for fuel or coolant leaks. Let it run for a few minutes with the heater on HI.
Some had said earlier you had to use caution not to spill any of the supercharger oil - BAH! We had the supercharger at all kinds of angles checking it out and never lost a drop. No issue.

This is a shot with the water pump off. The flange for the water pump on the case is clearly visible here. Pull it off and replace the o-ring. This is another problem spot on the S, and while you're here, you might as well get it. The o-ring is available at the dealer. There is one on the water pump itself as well.
Here is the 16mm mount bolt. This is also the one the tensioner tool is placed over.
The supercharger succumbs!!!! Very Happy
Here is as far as you tear down the motor for this install. Note that the block is the same on the Cooper.
The end of the pulley shaft has a plug. You can remove this with the method shown here:
Once it is removed, there are threads for a 13mm bolt that will be used later.
Now install the pulley removal tool.
Here's a picture of the supercharger compressor blades and the pulley removal tool installed:
Now that the tool is installed, place that 13mm bolt in the threads on the shaft. Install a gear puller on the removal tool using a pointed chuck on the center of the bolt. Then just crank off the pulley. It took a lot less than I thought it would.
Here is the bare supercharger shaft. There are no keys or anything else on the shaft - it is a pure interference fit. You can still see the bolt used with the gear puller
Lube the pulley shaft with some high temp bearing grease. Take the hub out of the oven with a welder's glove or hot glove and SLIDE it onto the shaft. Avoid banging the supercharger shaft at all costs. Make sure the hub is oriented correctly for the pulley to go on. Push the hub on until it is flush with the end of the shaft.
Here is the installed hub:
put the pulley on the hub with the supplied allens using some loctite.
You can barely see the new pulley and the allens under the black hose in this shot:
Now start the reassembly process.
Put the front bumper back on. Make sure to check all of the wiring harness connections on the intake, the fuel rail, the fuel regulator (the black piece at the passenger side of the fuel rail), and the lighting.
Fill the coolant system and flush the air with the bleeder on the radiator through the reservoir tank.
When you turn the car on, let it sit for ten seconds in the on position before starting it. That resets the throttle.
Start the car and look for fuel or coolant leaks. Let it run for a few minutes with the heater on HI.
Some had said earlier you had to use caution not to spill any of the supercharger oil - BAH! We had the supercharger at all kinds of angles checking it out and never lost a drop. No issue.
