REMOVING A VR6 SERPENTINE BELT TENSIONER AND LUBRICATING THE TENSIONER PULLEY BEARING

The following outlines the procedure for removing the serpentine belt tensioner from a VR6 engine and lubricating the tensioner pulley bearing. It is common for the bearing in the pulley to dry out, causing the bearing to become very noisy when the engine is running and eventually, to fail. The lubrication of the bearing as preventative maintenance or at the first sign of noise can significantly extend the lifetime of the tensioner pulley.

REMOVING THE SERPENTINE BELT TENSIONER

1. The serpentine belt tensioner is located on the passenger's side of the engine, as indicated by the yellow arrow in the picture below.

2. Remove the long cover piece on the passenger's side of the engine to reveal the tensioner. To do this, remove the two (2) T30 Torx screws (indicated by the yellow arrows in the picture below) and carefully pull upward on the cover piece.

3. The serpentine belt tensioner is indicted by the yellow arrow in the picture below. The tensioner pulley which applies force to the serpentine belt is indicated by the red arrow.

Page 4: DIY - Removing a VR6 Serpentine Belt

VWvortex Forums: DIY - Removing a VR6 serpentine belt tensioner and lubricating the tensioner pulley bearing

4. To remove the tension from the serpentine belt, thread a M8x**x1.25 pitch bolt into the threaded hole in the top of the tensioner unit (as indicated by the yellow arrow in the picture below) and turn using a 13mm socket or wrench until the serpentine belt is loose. ** is the length of the bolt in mm and will depend on the model year/version VR6 you have. Basically, you need a bolt that is long enough to fully remove the belt tension before the bolt head threads in completely, but is short enough to not interfere with the fuel lines overhead (red arrows in picture below). On my '99.5 VR6 a 60mm bolt works perfectly, however, on my friend's '00 VR6 the same bolt is too long. I recommend that you purchase a few bolts with different lengths and return the ones that don't work.

5. Once the belt tension has been removed, remove the tensioner unit from the engine by removing the three (3) 13mm bolts indicated by the yellow arrows in the picture below (Note: On some cars, these bolts will be 6mm hex instead). When the three bolts are out, slide the serpentine belt towards the passenger's side of the car and off of the tensioner pulley. You should now be able to remove the tensioner unit from the engine.

VWvortex Forums: DIY - Removing a VR6 serpentine belt tensioner and lubricating the tensioner pulley bearing

NOTE: If you do not plan on lubricating the pulley bearing and reinstalling the tensioner back onto the engine right away, I recommend that you remove the M8 tension-release bolt to release the extra tension from the spring inside the tensioner. While not likely, it's possible that the spring may be damaged or deformed if it sits for too long in an over-tensioned state. If you do remove the tension, make sure to thread the M8 bolt back into the tensioner and reapply tension to the spring before reinstalling the tensioner onto the engine. If you don't, you will not be able to get the serpentine belt back onto the tensioner pulley.

LUBRICATING THE TENSIONER PULLEY BEARING

6. The picture below shows the three main parts of the tensioner unit - the main body, the spring-loaded arm and the idler pulley.

9. Use a small screwdriver to remove the seals from each side of the pulley bearing, as shown in the picture below. To do this, insert the screwdriver between the seal and inner race and VERY CAREFULLY pry the seal upward. Make sure you do not damage the rubber coating on the seal or it may not stay in place when reinstalled.

11. Pack each side of the bearing with some high temp. wheel bearing grease or another suitable lubricant, as shown in the picture below. You can also add a drop or two of oil to thin out the grease if it's very thick.

13. Once the bearing has been packed with grease, carefully reinstall the bearing seals. MAKE SURE THAT THE SEALS ARE INSTALLED FULLY OR THEY WILL WORK THEMSELVES LOOSE AND WEAR AGAINST THE PULLEY GUARD OR TENSIONER ARM WHILE THE PULLEY SPINS.

14. Reinstall the pulley onto the tensioner unit and then reinstall the tensioner unit back onto the engine by following steps 2-8 in reverse. Remember that the pulley bolt is REVERSE THREAD - turn it counter-clockwise to tighten. If you have a torque wrench, the torque spec for the tensioner-to-engine bolts are 18 ft-lbs. I could not find the torque spec for the pulley-to-tensioner bolt, but 30 ft-lbs should be appropriate.

15. After reapplying tension to the serpentine belt and BEFORE starting the engine, check to see that the belt is properly positioned on ALL of the pulleys that it contacts.

Let me know if you have any questions.

EDIT (3/5/04): For those interested in replacing the serpentine belt, the illustration below shows how to route the belt around the various accessory pulleys.

You can do this, but it's a lot easier and cheaper to lube the bearing instead of tracking down a replacement bearing and installing it. I'm saving the bearing replacement until it NEEDS to be replaced. A dry bearing doesn't need to be replaced, it just needs to be lubed.

It could be this bearing. Give the lubing a try and see if it goes away. If not, check your water pump recently.

I lubed my tensioner pulley bearing 16k miles ago and it's been quiet since. Last week, I heard the noise again and figured that the bearing was dry ... again. I removed the tensioner and relubed the bearing twice ... it didn't help. I though maybe the bearing was fried and finally needed to be replaced. That was until my water pump bearing failed soon after. The tensioner bearing is fine - the relubing actually lasts for

quite a lot of miles. Now I just ahve to change the stupid water pump! That's the next DIY.

Mine's lasted 16k miles so far and is still good. Who knows. The seals aren't that great anyway. I don't think removing them has made them any worse. If the noise comes back relatively quickly after relubing then maybe it's time to replace the bearing.

Definitely post the number. At least that would give people the option of doing either one.

Yea taking the seal out is not the problem and trailer bearing greae is ok but I would sugjest a HIGH end Redline grease for very high speed bearings.

Good write up, nice pics - prob very helpful if you are really stuck for a bearing.

However, if you can hear the bearing, its dead - fact. No amount of greasing is going to make it better - the damage is done - replace.

The cost of the grease you have there is prob more than the bearing costs...!

Nice one Gary! I'm gonna have to do this soon too... But first on the list is taking appart the starter and cleaning it out. Mine's starting to get stuck for a few seconds after initial start up...

I'll make a write up for that as well.

It makes sense that the bearing is done when it starts to make noise, but if you catch it early it may be OK. My bearing was making a ridiculous amount of noise before I repacked it and has been silent ever since (16k miles). The pulley doesn't wobble one bit and spins ery smoothly.

Repacking the bearing will not cure everyone's problem, but is a good place to start.

The grease was extremely cheap - only a few dollars. I doubt I could get a bearing around me as cheap.

Yeah, that grease would be optimal, but is probably not necessary. When I purchased the trailer bearing grease, I compared it to a bunch of others, including some synthetics. The trailer bearing grease had the best high temp numbers and I doubt the bearing will see temps anywhere near the grease's limits.

dry bearings in anything make noise, but are not always dead.

He didn't leave the seals off. You need to reinstall them, and if you are careful, they will seal just the same. I've worked with lots of sealed bearings and removing and reinstalling seals is a no brainer.

Thanks again for the great tutorial. The tensioner on mine (2000 Jetta) required a 40mm long bolt to take all the tension off. Now it will be going up for sale (totally had it with the POS), it's really unbelievable the things that have gone wrong with a car that has 38k miles on it. I shall never return to the VW's. Great forum you got here though.
