water pump and cam belt

Postby Janeyblow » Mon 01.08.2022, 13:37

Hi All,
Like some others here.... engine overheating when stuck in traffic and less than optimum performance from the heater. Fans not coming on.
My local garage tells me it needs a new waterpump and cam belt but tells me that he cannot get water pump or cam belt kit.
Could someone please advise a manufacturer and part number for these please.
Thanks in anticipation
Janey

Hi, and welcome

The fans not coming on is probably a separate issue to the water pump and cambelt

It's worth checking the fan switch, their fuses and the fans themselves first.

The parts are normally available at SJS, PNM or can be obtained from Rockauto in the U.S.

There are other posts in this forum to point you in the right direction

I’ve used rock auto for belts pump and tensioner and other parts. Great value and delivery is not much longer than buying from U.K. based company.

As already said, fans and water pump/cambelt are 2 separate issues.
In addition to checking switches and fuses, also check all earth connections for the fans. They earth in a vulnerable area and are prone to rust.

Cambelt should be changed every 5 yrs and water pump etc at same time. Here is a link to the Isuzu page at rockauto

this is more relevant than it appears. you will find some people in this forum are more knowlegble than most Garages out there. if you happen to be local to one of them. their wealth of knowledge will help you a lot on all maintenance issues.

one thing that no one has mentioned is that the fans come on when the needle is around 3/4 of the way up. for a new owner, that is usually something you wouldnt expect. and testing the fans operation is very easy by grounding the thermostat plug to the engine or chassis. (ive done it with a paperclip)

PS, if you are in Durham. send a PM, I'd be happy to help.

Following on from the post from Tuga above, when you say overheating is it boiling over or are you assuming it is overheating from the temp gauge?

It is normal for the needle to stay just off the bottom of the scale when driving and to then rise dramatically to around the 3/4 mark when stationary which is quite alarming until you realise this is normal. It has caught myself and others out upon first taking ownership of an Elan.

Not saying cambelt and waterpump may not need doing but it is worth understanding if your car is really overheating.

If the heater isn’t getting hot when the engine is, usually that’s due to an airlock in the cooling system. Have you bled the radiator using the plug under the near side headlight pod . Possibly the heater valve is siezed closed as these are also suspect often need replacement

It is worth to have a look at the t(r)usty heater valve as well then.
