glow plug light and temp guage

[ATO]

A couple of weeks ago I lost the water pump drive belt..didn't notice straight away ..and when I switched the engine of and had a look it was very very hot, ie. the water in the expansion tank was boiling and it has p***ed out a load of coolant.
Anyway I replaced the belt and serviced the engine, seem to have got away with it & it's running fine. However since then the temp gauge has been reading much lower than normal and now has stopped moving at all. I was thinking maybe overheating had damaged the thermostat, now the glow plug light stopped coming on intermittantly and now has stopped altogether. What do you reckon? seperate issues or connected?
It's a 1.6TD and I'm not familar with them TBH

Hello,

you can check the glow plug light is working ok and rule that out by disconnecting the temperature connection to your glow plug relay. Usually you can just disconnect the temperature sender - this should make the glow plugs glow for the maximum period given by the relay (about 15 seconds typically I think), which should show up in the glow plug light.

You can test the temperature gauge is behaving sensibly by doing what it says here:

Thankfully the experts have written quite a lot of useful stuff about this!

Sounds like your diagnosis may be correct to me, but I'm certainly no expert!

Good luck fixing it

oh yeah - I forgot to say - you could check your temperature sender on the hose going to the cylinder head I think - square 4-pin connector, part number 251 919 501 I think.....

Cheers, I'll investigate further

make sure the wiring loom hasn`t melted on the very hot engine block as this fault could escalate and cause further problems.
