What to do.....?

Gents,

Just thinking in a ‘what if’ kind of way here, but is there a preferred course of action should you ‘be lucky enough’ to catch your temp gauge going East all of a sudden? I’m thinking in terms of once you stop is it best to keep the engine ticking over for a while to keep the water pump & fan working, or just switch straight off? This is all based on the premise that I’m not on a dirty great long beneficial down hill road, or that I have a Kenlowe etc.

Just thinking…….

Hi Mark, my preference would be to turn the engine off and wait for it to call down as leaving it running, there wouldn't be any airflow to the rad anyway and it would get hotter

Hi Andrew - wouldn't the fan be providing airflow?

And leave the bonnet up.

Only in relation to the engine revs

An engine running on tickover is timed with less ignition advance therefore the tendency is for it to run hotter, so you would be better switching off, or running it at a high idle speed.
