Overheating

Many thanks .

Thank you RobH yes I'm a twit I should have checked stat first, it was a brand new one so I presumed it would be ok, I've completely removed it a all is now fine. Obviously I'll need to replace it, what's the best one I can replace it with? Thanks again to all who have come to my rescue. Regards Alan

No I've put shim behind impeller.

Also this my be a silly question, when you remove pump from pump housing the first chamber which still holds a little water appears to be blanked off, ( no out or in let) is that correct? Regards Alan

Ok I've taken pump off which is a moss pump with the square four vane impeller, I've put in a shim as suggested (50 thou) also check head gasket, oil is very clean , it just appears that the pump is not circulating, would it make a difference if I remove thermostat completely? As it is still taking a very long time for bottom of radiator get hot. Regards Alan

Thanks all for your replies, I'll take pump off and check that out. Thanks again. Alan

Yes I've checked timing and retarded a couple of clicks also if anything it's running a little rich. I've noticed that the bottom of radiator does not get hot for quite a while which makes me wonder if the new pump is faulty!

Hi I’ve just finished complete restoration of my 1957 tr3, I’m having odd problems with over heating, when ticking over in garage the temp sits just over half way mark 75c. That all seems fine until I take car for a spin then temp shoots up to 100c in less than half a mile. The car has a a new radiator, new water pump, new stat,new belt, I’ve also flushed the system . Has anyone got a clue as to what is causing this. Also when I park car and leave engine running temp will drop .
