Aux belt change guide

[Chrisjk]

Anybody have one for a 172 ph1 please.

I don't think there is one.

Bumper off, headlight off - not required but improves access.

Drver's wheel off and sound proofing removed.

Removing the top alternator bolt helps make it easier to get the new belt on.

Make up some sort of tool to release the tension. 3/8" square drive but very poor access.

What size are the bolts holding the tensioners?

 

[mark123]

The tensioner pivots on a hex bolt and the spring is a male torx can't remember sizes.

Do you have a side on pic of the engine at all?

What do i loosen on this pic?

i loosen lower alt bolt, remove upper alt bolt/nut and pull alter down towards the front of the car, just makes it a bit easier as you have to put a s**t load of force on the tensioner

get a longer tensioner tool

So the little square female bolt next to the male torx needs to be loosened off to release the belt tension.
Is it the same process if i want to change just the belt/complete kit?
Cheers guys, think i can give it a bash, sod paying renault £220 in labour!

The square hole doesn't undo. It is like a lever that releases the tension when you move it towards the engine.
