U do not loosen any bolts to adjust tension.tighten all bolts first.Then with a 3/8 ratecht in the slot of the belt tensioner rotate the tensioner until you can install the belt correctly.then release the tensioner and take out the ratchet.

It would be helpful, but no special tools are required. Just look at what size bolt is on the Belt Tensioner, because that's where you will have to use a wrench to apply pressure in order to relieve pressure to take belt out. Good Luck.

there is a tensioner on the belt drive. if you look you will see a hole that you can fit a 3/8" breaker bar into and pull. this will slacken off the belt.

loosen the mounting bolts on the alternator, use pry bar to provide tension, and re-tighten.

First thing I would do is get your supplies. Antifreeze, lower radiator hose, 2 new hose clamps, serpintine belt, and I would purchase a Chiltons repair manual for your car. It is abour $15 for the manual but it will cover about very repair you will need to make as time goes on.
On newer cars you have to hold the automatic tensioner back with a wrench as you uninstall or reinstall the belt. Make sure you know or remember how the belt runs. You can put the belt most of the way on, then hold back the tensioner for the last step.
For the lower radiator hose, you need to drain the antifreeze from the radiator. The drain plug is usually on the bottom or the on the bottom engine side of the radiator. Make sure you drain it in a pan/ bucket/ pail as I believe it is against the law to drain it out on the ground and watch that pets/humans don't drink it because they will die. After draining it unsrew the clamps holding the hose on and remove the hose. Sometimes the hose will be stuck and twisting it or running a screw driver between the hose and the fitting will loosen the hose. Put the new hose on with the new clamps. I always use new clamp so you don't have to trust the old beat up/ stretched clamps. But don't throw out the old ones, as you may need them for an emergency repair sometime. Either put the old fluid back in(if it is still good) or put in the new stuff. Make sure you get the right mixture. You will need to run it a while and have the mixture checked.
Like I said about the book----it should cover both of these repairs, and tell you when to do routine maintence, the capacities of your fuel tank, radiator, oil, transmission, etc.

I hope this helps

go to www.gates.com , click on the Parts Locator & Interchange link on the left, put in your vehicle information, after you have put in the engine size look below and find the serpintine belt for you application, ie. w/ac or w/o ac, click the camera icon and there is your routing diagram, hope this helps, let me know

You should not have to take off your fan or your shroud to replace the belt. Its all under a tensioner pulley you have to put a 18 mm wrench on and pull towards the inside and you should see the belt loosen up enough to take belt off.

Chiltons repair manual has it (most auto repair centers carry it).It's usually mounted near the radiator (Belt layout)
