Has anyone else tried turning off their V6 then turning on the ignition and watching the temp gauge soar above 100? I'd expect the needle to rise a bit once the water stops circulating but mine is a whisker away from the red. Holy heat soak Batman!
When I switch the engine off I hear the pump try to run for about half a second then nothing. Can it be hotwired to check whether it's pump or wiring/fuses/relays? Last time I went hunting for fuses I got totally the wrong ones so thought I'd cheat and ask here first!

just unplug and wire directly to the terminals :y

Isn't that pump only activated by climate panel should passengers want heat with engine off?

I think there's two of 'em. I think the one you mean is under-ish the brake master cylinder. I don't have this one. There's another on the rad to disipate heat when the engine stops.

Ah, I'm on about the one on the rad. Never knew about the other. Will wait for a break in the monsoon and report back next July!

The pump on the radiator comes on with the first stage radiator fan switch, IIRC, but only if the ignition switch is off.
It's normal for the coolant temperature (remember, you're only measuring the bit that's in the coolant bridge) to peak a little after stopping the engine due to heat soak from the engine into the (now stationary) coolant. As long as it doesn't after-boil I wouldn't worry. If the engine is really hot when parked up the fan will be running and this leaves the aux. coolant pump running so there is a little flow to help it cool down.
