The tensioner pulley on my 1st gen gs300 crapped out and destroyed the belt. How do I replace the tensioner? Do I want to replace the whole tensioner assembly or can I just replace the pulley wheel itself?

 

you should replace the whole tension pulley its not that hard to change im not sure if its 2 bolts or 3 to take it of its one of those lolz just take out the top cover and the front cover where the timing belt is .

 

Its not the timing belt tensioner, it's the one for the serpentine belt.

 

i meant the cover that is behind the serpentine belt.. take out the inner cover and the front cover that is behind the tensioner pulley and you will see the bolts for the tensioner pulley

 

Sorry! Thanks for getting back quick!

 

no problem

 

May want to check the crankshaft pulley to make sure it's not gone, too.

 

Check out the pulley tensioner and crank damper. I am in the process of changing the crank damper myself. It is torqued very tight.
