Another timing belt question

[Pete Boole]

In people's experience, once the timing belt tension is set how many miles does it stay within spec?

Thanks

I'm looking to replace mine next month. Been on for 5 years and 15,000 miles. Still good.

It's the worn pulley that's scaring me

The belt will loose tension after only a little use, but that's still within spec, as the original figures (90-95 etc) are for a new belt, and shouldn't be applied to a belt that's been used.

Thanks guys! The reason I'm asking is because my belt tensioner is eventually going to be half hidden behind the blower drive pulley. The only way to re-adjust the tension once it's all installed will be to remove the accessory drive belt, blower belt and crankshaft pulley, but if I only need to do this for a belt change every few thousand miles it won't be an issue.

Switch to auto adjustment

[AndyC]

The semi-auto adjusters are known for the piston sticking, so they're not great.

Defo staying with a "manual" adjuster. Will also be using a further two on the serpentine belts for the blower and the a/c compressor/water pump/alternator.
