Avoid Dayco timing belts kits. My workshop recently used a kit on a Colorado. The auto tensioner failed causing major damage to the cylinder head, this happened within 2000kms of being fitted.
The part at fault was the tensioner spring stopper, the aluminum wall thickness is thin and broke, causing the belt to come loose enough to skip teeth, allowing the pistons to hit the valves.
The claim was legitimate, two other mechanics witnessed me undo the retaining bolt from the tensioner. The warranty department are blaming the failure on a loose retaining bolt. There are clearly no witness marks on the back of the tensioner, or in the locating groove to hold it in place. This is an obvious place to look to prove whether the bolt came loose or not. Please see the picture provided showing the back of the failed tensioner and the new one. No marks at all proving it didnt rattle on the retaining fork, or come loose in any way.
We have never made a claim before either, and were not given the chance to argue our case. This workshop will never use a Dayco timing belt kit again.
