Coolant leak and Overheating?
the thermostat seal is weeping something terrible, losing about 500ml for 50-100 miles, so keeps needing topping up until the part arrives. My partner uses the car for work -im just the tech!- and didnt top it up at all last week, then complained the heater was cold and I had to top it up about a litre and a half.
What worried me is that before topping up the temperature gauge was at 9 oclock and not red light, but the dash test said the coolant was 125degrees c. Surely at that temperature the needle should have gone beyond 9 o clock?

Well, the square rubber seal was causing my loss, underneath the engine cover on the outlet pipe, so not easily spotted.

At that temperature the light was probably just about to come on or maybe the light itself has failed. You are heading for a much, much greater bill than just replacing that leaking seal.---------- KEEP that rad topped up or soon you will be walking or travelling on the bus.--- |

As I thought, my partner was watching the needle but as it hadnt changed didnt think anything was wrong. What controls the needle out of interest?
Since seeing that temperature I have firmly made it clear that the coolant must be topped up everyday before coming home until the thermostat is replaced...
