My van started overheating back when we had the really cold weather. I changed the thermostat which made no difference.
The radiator seems to be barely warm so I suspect the water pump may be faulty?
Anything else I should consider b4 replacement?

Have you considered the possibilty of the main rad being partially blocked,,,,,

How is the Cab heater performing ?

Fritz,,,,,,,,,,,,,

is the alternater still charging?

Fritz , good point, no I had not thought of the rad as it was cold ...... the cab heater works slightly then nothing at all.

weldore, no the alternator is not charging but belts intact...... need adjustment u think?

are both belts intact?

have you checked if the alternter and pump are turning when the engine is running?

yes both intact ... have not measured the play in the water pump belt but not excessive

and the pump and alt is turning when running

yes indeed ... no squeal from the belt ... some antifreeze residude around casing of waterpump but no leaks? I think the alternator may be a red herring as I think it is on its last legs anyway ... it was working (just) until today when no red light showing on dash

well it coud be as Fritz says or maybe the impeller in the water pump has crackered..but its strange the alt is not charging.these symptoms are usually belt problems.did the alt stop working when the engine started over heating? or has it been a seperate matter...sorry to say i dont know other than that.but wait for more replies before you take it to bits..sorry m8

oh one thing to check is if the thermostat is no sticking..do you know where it is?

Thamks, forgot to mention that I removed the thermostat today and it still overheats (jsut takes longer to do so )... will check belts properly and flush the rad then post back ta Keith

You have bled it properly havent you????????????????
