Hey guy,

My car need a new belt, the old one is crack and splitting. Time to replace a new one.

can someone tell how to replace the belt? where is the automatic belt tensioner? and how do I turn it.

thanks in advance!

16mm Socket and a ratchet for the Main belt

I Use the HD Gates belts they have cross cuts for better grip as the 55s have belt slipage at upper rpm s

 

also remember to look in your manual for the belt path,easy to forget when the belt is off.

this is good infomation so I just turn the 16mm bolt in the middle of the pulley counter clock to release the tension?

thank you ohLord & Mark!!

 

Guys, I don't have a 16mm bolt,
what i have is a torx style head. Is this the right one to turn?

thanks

 

and probably your 02 are all different.my 99 has a bolt with an external torx thru the center
this diy has the tensioner nut below

I think you have the new style so

should be the one to follow,since it has the fins as displayed in the

PLEASE take a look at the Tensioner ...

The Tensioner has a 16MM Casting off to the side of the tensioner
do NOT use the TORX bolt to loosen the tensioner as the Torx bolt WILL Unscrew..

 

Thanks guys! make more sense now.

I thought it was the torx bolt in the middle of the pulley.



thank you all
