Take it for a run, if the expansion tank is still cold maybe you've got an airlock. Have you had any major disturbance with the cooling system of late? If you go through life with your head in the sand....all people will see is an ar5e!!

Sounds very much like the water isn't being circulated, so pump would be my guess. I've seen a couple of pumps where the vanes have corroded away to the extent that they just don't push the water around anymore. Darren

@LRA - thats my thought at the moment, I will check to see if the water is moving in the pipes and heater tank
also - check for air locks |

Does the heater work?
That would show circulation. |

before you strip out the thermostat it would be worth checking for an air lock. if i recall bleed radiator top plug first and then the plug on top of the thermostat housing. BM52

good call bm52 - yes I will try that first, so is that the brass plug next to the thermostat or the plug ontop of the radiator (probably the plug ontop of the radiator)

from the workshop manual..
1. Remove plastic plugs from thermostat housing and radiator. 2. Fill cooling system with 50% - 50% of water/anti-freeze mixture. 3. Fill from expansion tank until radiator is full, with level in expansion tank the same as in radiator. NOTE: Care should be taken to avoid excess coolant spillage from radiator. 4. Fit plastic plug in radiator. 5. Add a further 1 litre (1.76 pints) of coolant to expansion tank and allow to settle. 6. Refit expansion tank cap and thermostat housing plug. 7. Run engine at idle speed for five minutes. 8. Switch off engine, check that expansion tank coolant is level with top of indicator post and top up as necessary. BM52 |

bm - thanks for the list, I ran thru the procedure and the engine is normal however the expansion tank is still cool / cold, been on a 5 mile run and temp stays in middle. maybe it was an airlock. certainly going to keep a close eye on it.
I think because its not used much the thermostat was stuck closed ? I took the brass plug out of the radiator housing and squeezed the pipes and the fluid is moving when each hose is squeezed (so thermostat is open) and the coolant moves about in the expansion tank so it does not look like there are any blockages taking her out on the plains tonight, so we'll see how she behaves |

Poor earth is my guess...... Try turning lights and heater
On, if gauge goes up then you have bad earth. Have fun be happy |
