So when you park at work, does it creep a bit higher, perhaps, maybe?

Sorry

That's my final offer. It rarely shows 94. It doesn't go above when I park

Now there's a comment of a man that does not like to be wrong

Now Steve, if you park it up for 4 hours and leave it running with a brick on the accelerator... Are you sure it does not creep above 92-94

Good luck with it Steve, I hope its not the dreaded HGF... Lets hope its something a little more simple...

After 4 hours running it would run out of fuel

Fingers crossed

When my 1.8 suffered HGF there was mayo very evident on the dipstick as well as the filler cap, may be worth taking a look too.

Thanks Phil. I'll check that tomorrow.

Just trying to establish the facts Pete!

O.K. Steve; if your head gasket was failing we would expect overheating, but you have none. We would also see mayonnaise on the dipstick and/or in the expansion tank, but you haven't reported any. All we have is some deposits under the oil filler cap which normally indicates condensation which isn't being dispersed due to the engine not getting sufficiently hot; hence my obsession with your coolant temperature.

Your small coolant loss might be through the expansion tank cap seals. If this causes a loss of pressurisation, running temperatures would be cooler on the move but rise when the ram effect stops. I'd like to know what happens if you ever get stuck in a traffic jam.

I shall keep an eye on things in more detail over the next couple of days.

Ok, been out for a drive this morning with the aircon set to 'econ' mode. 92 degrees whilst driving at speed. When pottering along in traffic the temp rises to 96 and then settles back to 92. Have thoroughly checked all over engine for any sign of external coolant leak and none seen.

Steve916 · 17th February 2013, 11:30

I have also checked oil level. Hasn't risen. Normal colour. The smell when I open the oil filler cap is of hot oil, not coolant.

Thanks Steve. I don't think you need to worry about HGF. In fact, I'm very jealous of your coolant temperatures.
