Just as the title asks. My car is at 100,000 miles and I will be replacing the timing belt and water pump. Should I also change the belt tensioner and spring?

 

most likely the O.E. tentioner and spring are in good shape but if you have the coin, might as well replace it for piece of mind. Some internet stores have all those pieces as a kit. But i'm sure some will disagree.

 

I am currently rebuilding the cylinder head and spending way more than I should. I just want to make sure that replacement of the tensioner and spring is really necessary.

 

I didnt replace mine.
Just look at them and see if theyre fucked up, theres not really a reason to replace them otherwise.

Replace everything in there and save yourself time and money! Because not replacing that could come back to bite you in the ***, IMO.

good advice...

 

Just to give you an example- My friend had a motor built, had new rings, rods, JE pistons, main, and rod bearings replaced along with machining, had all that done, but used the old oil pump because it was working fine before he decided to build the motor. 5k miles later, he called me to find out why his car was making a loud screeching noise, then died, and wouldn't start- the oil pump went out. So, spending that extra $175 more would have saved him a newly built motor, and a lot of time.

 

PreFerio speaks the truth....

 

definately replace the tensioner. I've seen one seize up and burn up the timing belt. Why take a chance?
