Supercharger belt replacement

Supercharger belt replacement
Ok, before I start let me say that I do know how to use and read the JTIS. The instructions say that before removal of the supercharger belt one must first remove the cooling fan and shroud (26.25.25). Drain the cooling system, detach the ac tube, remove the radiator hose and intercooler hose, the wiring harness and the motor shroud bolt.
I removed the shroud bolt and the wiring harness but I don't see any connection to the hoses mentioned, I still am unable to lift the fans and shroud up and out. Does some one have a more descriptive procedure for removing the shroud. Chilton and Clymer manuels are better than the JTIS although I can not find one.

super charger belt
I recently changed mine. You may want to do the main belt while you have the fans out. Both belts are about 70-80 bucks
1/ Drain coolant passenger side (usa) bottom of radiator theres a black plug.
2/ Remove passenger side top hose into radiator
3/ Remove driver side top hose into radiator.
4/ Unplug elec connectors into the two fans and cut out the cable ties
5/ Undo the two nuts that secure the fan housing 3inches down from the top on either side.
6/ Lift out fans they side up
7/ Remove super charger belt with a square end drive 3/8 I think on the lowest pulley. That's the adjuster one.
Reinstall is reverse but remember to check the flaps at the bottom of the fan housing are in place after you have put the fans back. They tend to get caught. Also dont use the Jaguar brand belts as they tend to squeal other after market belts have better technology these days. Remember to bleed the supercharger after you have refilled the coolant.

Here is a post with some more info on how to change the belt without having the need to drain coolant and remove the front fans. I can switch the belt win about 5 to 10 minutes this way.

You have to drain the fluid and remove the top hoses on the XKR as you cannot get to the bolts and the fan housing will fit between the two top hosed. Even with the Jag tool to turn the super charger pulley you will find it very difficult to get the belt out past the fan housing.
The bonnet is not the issue. Job takes about 20-30min

If your changing the main belt I found I had to loosen the supercharger adjuster pulley in order to get the main belt out as the gap is very tight.

BTW, you can get a Goodyear Gatorback 4080515 supercharger belt at Amazon for $26.05. Lots of folks consider these the best belts..especially for the supercharger where slippage is very undesirable....and this is a great price with free shipping. Seems like they only keep one in stock at a time, but then they come back in stock in a few days.

No, it looks like the belt size changed when they went to the 4.2L in 2003. Try the VIN decoder on the Goodyear site: http://www.vindecipher.com/veyance/

This looks like the equivalent 4.2L Goodyear Gatorback belt on Amazon:

I must admit I change my belts exactly the same way as avos and have made exactly the same tool (great minds and all that ;-) But for someone who does not, the easiest way is take off the top radiator hose at the radiator only and lift it up out of the way, I often tie a larg cable tie around it to hold it there, remove the fan assembly and then you have easy access to the lot, and like has been said attached to the fan assembly are a couple of pipes for the aircon. Once done put it all back and just top up the coolant, go for a short drive to get the air out the system and Bobs your uncle.
I wont deny I have done it on a roadside with just a lever bar and removed nothing but it is fiddly and damn hot

Avos,
I`m thinking of buying the supercharger belt tension release tool, but before I do I want to ask you if you can change the belt with the aid of this tool and do it all from the top, ie you don`t have the car on a lift to have access to the underside to do this do you? I want to change my belt without draining coolant and removing the fans...thanks in advance...
