Serpentine Belt Problems

[Gareth A]

Hi everyone,

 

The the other week I broken down with my 2002 3.0V6 S type, when the serpentine drive belt came off. 

The fault turned out to be a worn tensioner, so this was replaced, which has solved the problem. Of course its good practice to change the belt at the same time, but this has flagged up an unexpected problem.  

The belt that all the motor factors say that's fitted to my car is part number 6PK2270, but the one that's on my car is 6PK2748. They can't understand why my car has this, and they are struggling to get it.  

Has anyone else encountered this problem?

 

Thanks in advance,

 

Gareth.

Hi Gareth,

I replaced my belt during a service, and TBH I have had hassles ever since. It was really tight and a bugger to fit, and I've been getting a variable and intermittent squeak since then. I'm starting to suspect this is the tensioner, but I'll need to conduct some tests to be sure. It could be it's slightly the wrong belt, which caused the additional tension and the squeaking, but my spares supplier is generally reliable in these matters. I don't have the part numbers at hand to check.

Hope you get it sorted, Russ

Hello Gareth, i had a similar problem with mine.... and a well know motor factor.

When changing a the top hose / heater control valve / the Radiator (id only planned on the heater control valve - but....one thing leads to another scenario) i noticed it (the belt) had cracked severely so knowing the headaches one of those causes ( I also have a Land rover Disco) i decided to change it. 

Asking the motor factor if in stock by phone....yes we have and they've got two different ones both apparently for the car. How can that be i asked? Reply being don't know!

I paid for both and set off to deal. I compared them to the one that was on it and we had three different sizes the biggest difference was about 120mm smallest was 85mm... but nothing remotely near mine. Added the fact that mine didn't have a number on it so that made it a bit tricky to ID.

I went back to motor factor with all three belts and we tried to sort. They admitted defeat and refunded the money. I then called local Jag dealer. Yes we have one was the reply. It was twice the price but matched my original. The slight complication in all this was that my Disco was also off the road  so out came the push bike for a 28 mile round trip.

Hello All,

I had a similar experience the first time I changed the belt, Jag in bits, a mate running me back to the Motor Factor, armed with the original and the incorrect one supplied, only for them to admit defeat and give me my money back.  

I did manage to get one eventually the first time round, but this time (after the tensioner incident), the same supplier drew a blank. 

I called the local Jaguar dealer and explained the problem - they ordered the belt that their system says is fitted to my car. 

I visited Hatfields Jaguar to collect the new belt this afternoon. .  Twice the price of course, but sure enough, its the correct longer one. Its approx 2.75m long    

The part number on the invoice for the correct belt - AJ8 4136 - if you reference this back online it points to a 6PK2275 belt, (2.27m long) which is too short for the car. 

So, it seems that this is where the error lies. 

Cheers,

Gareth.
