Good evening everyone
I have an issue with the cooling system in my car.
It's a 1996 1.8 vvc fitted with a rover prrt. The engine has been rebuilt by DVA, last year and fitted back in the car in March 2011. It has only run a few minutes at any one time due to the overheating issue.
When Dave rebuilt the engine, he found a lot of radwell residue inside the block.
The engine overheat very quickly when idling, looking at the water temp on gauge, it seems that there no coolant flow.
I say it seems as when I look inside the header tank I cannot see any water coming out of the engine return outlet and I can feel any air movement when I put my finger in.
The radiator stays stone cold but the inlet and outlet are hot, all pipes are hot
Are those tests valid to diagnose a failed water pump?
Is there a way to test the water pump without running the engine?
Do I have a massive air lock somewhere?
Can I assume the water pump is a standard K series item and not a “special” Caterham?
Thanks for your input
Jack
