Broken Timing belt.

[Ken H]

Basically doing a guy a favour here as I sold my 172(mk1) to him 2 years ago and I said Id try and get as much information for him as I could so here it goes.He had the timing belt done about a year ago as the title suggests it snapped.What they are saying is the fan belt broke which in turn rapped itself around the timing belt cover and somehow broke the timing belt.Is this possible?Has it ever happened to anybody on here as it sounds a bit far fetched to me.

he is still buggin you after 2 years?

not sure persoanlly.... Edde will tell you im sure

 

[Andy_J]

anything is possible mate, it's a renault!

 

[Ken H]

To be fair to him I found out through another guy and I felt Id like to help him out a bit! The car I have to say was a gem and gave no trouble until now.Hes now looking at a big bill for an engine rebuild ! I just thought the 2 belts were completely seperate and if the fan belt snapped it would be an easy fix.

 

[S22 JGS]

nasty.. where bouts he based?
will be much cheaper if he goes to one of the greese monkey guys on here

 

[Tom]

Its possible.

Its quite common

 

[Ken H]

Its quite common?Can you explain how? Based in southern Ireland.He'd nearly be better off getting the car shipped over and getting somebody half decent to look at it.

 

[Ken H]

He also tells me the fan belt was replaced also when the timing belt was done.Does he have any comeback whatsoever?

 

[cupholder]

yep it does happen seen it so many times and not just on renaults :rasp:

 

[TomTom]

Yeah it can, and has happened. Most dealerships/garages don't know to change the alternater belt on 36k (due to the water pump) not just the 72k Service so they have a tendancy to go

Does a 172 even have a fanbelt? I know the mk2's don't

No, it's all electrically operated. The AUX belt is often referred to as the Fan belt.

 

[G_F]

This is why an AUX belt should be changed well before the 36k service, the same as you wouldnt chance your cambelt to 72k

 

[Martin_172]

very common problem, seen it happen loads with the AUX belt snapping and taking cambelt with it.

 

[Fred@BTM]

yep thats common, the cause IMO is due to NOT inspecting the condition of the aux belt tensioner, its normally this that fails which in turn causes the aux belt to go which then 9/10 times gets sucked into the cambelt

yoz is irish, and i'm half irish, could be a good excuse for a weekend bender/come over to fix the car lol!!!

 

[philmots]

Someone told me the cups dont have a tensioner on the AUX belt due to no aircon and a simpler arrangement. true?

 

[Fred@BTM]

the tensioner on a 172 cup is built into the alternator braket

 

[Ollie82.]

Is the AUX belt on a Cup an easy job?

 

[Fred@BTM]

15min, if you're a mong 30min

 

[philmots]

Gottcha so to replace the tensioner on the cup you need a new alternator bracket?

 

[Fred@BTM]

you don't need to replace it mate, have a look, its uber simple, its just an M8 threaded bar with a dongle on the end basically

how much is it to have a aux belt + tensioner done on my 172 ph1

 

[edde]

how much is it to have a aux belt + tensioner done on my 172 ph1

2.7 hours labour for the belt a bit extra for the tensioner
Belts £12 the tensioners £80 or so.
