Title: Leaking water pump?
Post by: billabong on 05 April 2013, 18:04

Car squeals like a pig when you start (1.9SD - 1Y?)
The revs show low until the squeal goes away (guessing due to rev sensor being on the alternator?).
Here is a photo of the pump and its belt. Looks wet around it and I noticed the water level being a bit low...

Ive got a new belt as it looks buggered, whats the likely verdict on the pump? New pump needed? Or just some gasket sealer?
Cheers

new pump, not worth putting sealant there... will not last a day
also put in a new thermostat, worth doing when you replace the pump and it's so much easier with pump out.....

car should not be revving low, the speed sensor is not in the alternator ;)

Thanks!
I was under the impression that this diesel engine used a sensor on the alternator for RPM ?
Will try and get hold of a pump...
