SOS! Stopped at roadside with zero water temp

[Dr Mike Oxgreen]

Stopped because I noticed the water temperature at zero.

Expansion bottle is full, but I don't have tools to undo the nut on top of the swirl pot. Daren't carry on in case it has lost coolant, although there's no evidence of a leak.

RAC on their way, but in the meantime can someone tell me which fuse the dashboard water temperature gauge is on?

Ta!

PistonHeads - the fifth emergency service.

Wires still look attached at the sensor end, and I've wiggled them with no response. Maybe the sensor has failed.

[Dr Mike Oxgreen]

Just realised I've been looking at the ECU sensor. Can't see the gauge sensor; it's too dark down there. So it could be that - the RAC guy will have a torch.

[Dr Mike Oxgreen]

There's no evidence of water loss so I'm 80% sure it's the sensor or gauge, just want the RAC guy to help eliminate the other 20% of doubt. I'll really kick myself if I overheat it and warp the heads.

[Dr Mike Oxgreen]

The RAC guy had a torch, and after I'd directed him to where the gauge sender is we could see that the connector had indeed fallen off. The plastic looks a bit knackered so it could do with replacing. Distributor cap off to gain access, and a bit of fiddling with bent-nose pliers, and the gauge came to life.

Thanks for everyone's help!

At least we were stopped in the shade, and the locals were friendly...
