Hi,
Just run my car after a couple of weeks stood still.
When I got out at my destination, the car smelt very hot. Popping the bonnet I found the bottom hose to be highly pressurised. So much so that it was almost solid. It was hot. So too was the top hose but the metal plate on top of the rad was cold???
The heaters blow warm ok and no other pipes are cold, so the water seems to be circulating ok. Could the pump have gone?
How would I know?
The car isn't overheating. The gauge reads normal. Fans also kick in as normal. The heads were baking though.
Anyone any ideas?
Cheers
Rich

Is the hose from the header tank cap overflow to the overflow tank blocked..???? if the water cant overflow then to mucch pressure will build up in the system..??
You can take the hose off which goes to the header tank cap and blow down it towards the overflow tank to see if air travels through it..

Hi Dan,
Yep, first thing I tried that (great minds and all that)
It's fine.
Think I may have sussed it actually. Think it was an airlock in the top of the rad.
Rad top was cold when everything else was hot. Drained the rad a bit, topped it up again at the header and bingo. Rad came warm. We'll see if that cures it.
Cheers anyway.

the metal plate on top of the rad is only bolted to the core and I wouldnt really expect it to get warm..

Thanks David,
Is it normal for the bottom hose to be VERY pressurised while the engine is running, like so hard that it is solid?
I'm maybe being a bit paranoid, but it doesn't seem normal, as if there is a slight blockage, restricting the water flow but nopt stopping it. Might drain the system later and see if any cr@p comes out.
Cheers

I dont think it should be any harder than the others.. they can harden over age.. I would give it a good flush out if I was you..
