MG MGF Technical - over heating?
I think i might have a problem with my vvc, after a motorway run the car will suddenly heat up when i have to stop in traffic for a while. The fan comes on and the water temp will rise over half way ( normal sits just below halfway ) then the fan will cool it down back to below half way. The expansion tank level is normal do you think i might have some air in the system? I have let some air out previously from the radiator bled point.
Just a bit worried don't want HGF!!
|It is perfectly normal.|
DO NOT switch off the car immediately after a motorway run (e.g. while refilling). Wait for a minute (fan will go on and off).
|It's not normal for the water temperature gauge to move off the standard 'one notch under half' mark. The gauge is very heavily damped and any movement is a significant rise in temperature - usually only lasting briefly before something serious happens!|
If the radiator fan is kicking in correctly it should be holding the temperature down to normal at all times. Are you sure the rad fan is operating?
|Sounds like the radiator is badly corroded and only giving very minimal cooling, or you have an air lock or you have a sticky thermostat. All bad and not normal if you are using a standard gauge. If you are using a non-standard gauge (such as the one on my midget) then this is normal behaviour.|
Thanks for your help have ordered a new Mike satur radiator and under body pipes hopefully this will help. The other Radiator was a bit rusty and the fine fins were breaking off!!
