2010 Chevy colorado 2.9L
Had a timing chain and tensioner replaced, by a Mac. Shop.
4,000 miles later. The tensioner is bad / became loose again. And they wont fix it again.
What would cause this. I'm thinking they messed up. Or did not replace everything. Or maybe something else at fault. Should I find another shop to fix it or, junk the engine.
When they fixed it, the truck ran perfectly.
And when the issue started both times it was a slow, transition, over a 3 week span. like the tensioner was slowly moving away from chain.
I do know about engines and how to fix some things, but I'm not a pro. And have used YouTube to fix a lot of things on my own. So... what do u think about this. Did the shop not do something correctly or used old parts. They claimed they used OEM parts. Ideas?
Did the shop replace the entire timing chain kit, or only a few components? Was there a warranty of any kind on their work and a list of replaced parts on the work order?
they claimed they replaced chain and tensioners. and i asked for warrenty. but no warranty. they used OEM parts.
