Technical Aaargh! Help! Please! Alternator belt snapped and now wont start

[devilbelly]

Hi everyone


Desperate help needed!!!


My other half just bought a 2002 Sei Schumacher


Today I was driving it at half way around a roundabout it died

I had a look and the alternator belt had snapped and shredded!!


The car has no aircon and it is just attached via the alternator and crank pulley


Now, when you turn it over it is turning a bit then going quite high pitched and not sounding right at all. It is not firing at all


The cam belt is not snapped and the engine is turning seemingly okay on the key


The crank sensor appears intact


I am quite stumped


Can anyone help? Or heard of anything similar?


Thanks in advance

did you have the bottom pulley off to change the belt?

I haven't touched anything. Its currently sitting at home (AA recovery) with no belt on. It would still start without the belt wouldn't it?

Possibly, check the timing.

There are a number of possible issues in order of probability:
1. Alternator belt got caught in timing belt causing it to skip a tooth or two
2. Battery is too weak to start car
3. Belt caught on a sesor or wire as it came of and broke it
4. Alternator failed and damaged electrics.

For 1 you need to check the timing, 2 try a jump start, 3 inspect engine bay, 4 Rule out 1,2&3 first.

Crank sensor is very close to the bottom pulley (necessarily so) and can be damaged by a belt failure.

Belt failure may have been caused by a failing alternator, so battery is flat.

Thanks everyone. It looks like the belt shredded and went in the timing case as a couple of you mentioned ?

Thank you for your help ? much appreciated

Hi,
Don't just re-time the engine, change the belt. Consider changing tensioner and water pump too if not done recently.
