rapid overheating

<< < (4/7) > >>

Range Rover Blues:
From memory I'd say that the cheap ones have a flat plate on the bottom ned, the end you don't see on a "normal" stat, this closes off the bypass flow once the engine heats up.  Better ones have a dished plate which is then sprung.

Go for branded, or OEM.  If in doubt I've found Devon 4x4 very helpful with obscure stuff, and if you have deep pockets Rimmers are just as good.

jkseries:
Brilliant.

Thanks

Going on from what Range Rover Blues has stated, I replaced a thermostat a couple of years ago with one from Halfrauds, had no end of trouble after it was replaced. I replaced it again with an OEM and sorted it out nicely.

Right... this is till ongoing.  It now has a new stat and water pump but it's still trying to over heat.

I've just been reading about 'p' gasket problems. It sounds like mine is leaking from a similar place.  Is it common for the 'p' gaskets to go?

I'm struggling to find why mine is over heating. The heater NEVER gets hot so could be a blockage their but surely the rad in the heater isn't crucial to the cooling of the car.

After a run out today (needle sat at about 3/4 ) I could hear a hissing from behind the water pump.  I felt the radiator. The top was consistently HOT across the width and the bottom was consistently cool.

I would have expected it not to be even if it was blocked.

Where can i look next? Investigate the 'p' gasket?

Can someone tell me how the water flows around the engine. Hot water into top of rad. water falls through rad and is cooled. Water pump pulls water from bottom of rad then back into engine? Something like that.

Thanks

recent issue i had with over heating was with the very small breather hose going from the stat housing back to the header tank being blocked solid. this was causing air locks in the stat housing and preventing water from circulating? only found it when i was so [!Expletive Deleted!] off with it all that i had all hoses off whilst flushing the rad.
