V8 Overheating

(1/6) > >>

Dr Strangeglove:
My Rangie recently overheated and I had to change the head gasket which, with a lot of help from my friends is now done.  When it was back together we ran it for a good hour (half an hour at a time) and everything seamed OK. :lol:   Yesterday I took it out and it was OK to start with then whilst I wasn’t looking it got very hot (just below the red) which gave me a bit of a panic. :cry:   The last thing I want to do is blow the heads again.  With £200’s worth of skim, test and gaskets, and all the hard work involved, I need to get to the bottom of the overheating before I start to enjoy using it again. :roll:

I have removed the thermostat so that can’t be causing any resistance or blockage so I have come to the conclusion it must be the water pump or radiator.  Are their any tests I can do to find which one?  I don’t want to start shelling out lots of dosh as this is my toy and I don’t want it to become a money pit.

Any ideas will be received with thanks. :idea:

Regards

Mick

for the sake of it, i'd back flush your radiator. and if that doesnt help get your pump tested.

Is it air con?
Had resigned myself to the fact that I had blown head, got all the spaners out ready to strip, first job was to remove rad.
Once removed I found so much muck and crap trapped between rad and air con rad I thought this could be the problem.  Jetwashed both rads and put it back together, Problem solved  :D

If you get this months LRO it takes you through the tests, compression, cylinder leakage etc.

I had the same problem, but my radiator was shot once I hosed all the rubbish off.  Radiators aren't cheap, I got mine for £15o from eBay, genuine part is loads more!!

Dr Strangeglove:
Can I test the water pump myself or is it a guarage job? :-k
