19S Overheating..

[Manta78]

My car is overheating and could it be that the rad is a 3 core and that the fan isnt powerful enough to pull air through?

any ideas?

[spiney_norman]

Is it actually overheating or is the voltage regulator on the back of the dash clocks knackered? That would be my first check.

naw not looking at the dash at all the engine but mainly the rad is getting really hot after a short time of running

[Manta78]

Yeah radiators the wrong one..the fan doesnt seem to be strong enough to pull air through the radiator . So could i just take out one of the cooling vents? would this work?

Is the thermostat working ,lower hose getting hot ,hearted getting hot ,not air locked

[Manta78]

took out the thermostat just to make sure it wasnt that , heater hoses getting warm but i took out the rad and refilled it and it seems to be a whole lot cooler now so there could of just been an airlock in the rad so all good now

Put a mg b gt stat in 75 degrees will be ok. Around £5 on ebay

If you take the thermostat out on a CIH engine it messes the water flow up badly and can make the engine overheat.

[MANTAMAN]

 Flush the cooling system, particulary the heater matrix, that often get clogged with sediment.

 

 When you have refilled the system find somewhere on a slope/hill you can park the Manta very nose up and get it hot enough for the thermostat to open, this will get airlocks out of the system, keep it topped up while doing this.
