I've flushed the cooling system (drain on the rad), but I have a cooling issue.

When driving the temp will rise to over 100, but if I rev the engine it'll drop to what I'd call normal running temps.

Could I have an air lock or is it more likely to be the water pump thats failed?

This is on a 3.0 V6.

Cheers!

That sounds like an air lock, when you refilled, did you burp the system with the filler cap off?

What was your reason for flushing in the first place?

[UrbanFox]

Reason for flushing - car's been stood and I wanted to make sure it had decent cooling, plus it was doing this before flushing it.

I did alot of squeezing of the top hose with the heaters on hot and the cap off.  Once I've replaced the fuel filter (damn things developed a leak!) i'm going to try and bleed it again.

Cheers for the replies!

If this was happening previously and the car has been standing for a while. It may be a good time to do an oil change inc. filter. Not all overheating probs are caused by water cooling system.

Thats on my list of jobs to do!
