Engine Cooling & Radiator Problem – Any ideas??

[fatboyz39]

There might be a small leak from headgasket pushing gases thru the cooling system. This can be cause thru detenation. As i said i was in a similar situation and learnt the hard way by changing thru 2 head gasket only finding it wasn't the issue it was detenation and cause the head gasket to leak.

The added pressure is there which cause the overfill bottle to fill up, and not return to the system.

Here is a simple test. When cold start up the car, lets say 2-3min. turn off and remove the radiator cap. When you relase pressure cap if abit of coolant comes out thats seems normal, but if a shitload of coolant bursts out then you have a headgasket problem.

OEM thermostat

I died only 4 months ago so its brand new

It's not pushing it out anywhere near as fast with the new radiator so maybe I just need a new low temp one?

OEM thermostat should be more then fine. No point getting low temp thermostat without a lower thermo fan switch.

What's the course of detonation? My e-mang is tuned for 89 Oct so that should be very safe running on 98 Oct..

Ok Jimmy I'll do your test tomorrow

Thanks for the tip

worn piston rings.

Do a leak down test...that'll show whats going on. It takes a good 1-2hours to do.

thermostat open to late and radiator couldnt cool it in time.by takign out the thermostat is just saving u money doing the leak downtest and if this doesnt help then go do a leak downtest..

what about a cooling system pressure test? You probably have had that done already yeah?Holds pressure?

Jimmy's Test Complete:

Bit of pressure when I opened the cap but no coolant came out, I've opened it before when really hot and only a bit came out that time... good or bad?

sounds normal.
Wat coolant are you using? Its not the cheap stuff isit? cos i rem that one my sister's car the cheaper coolant was the problem.
