Google ;)

Temp guage sender

temp gauge sensor :boggle:

The coolant temp sensor has a blue plug on the end. I've searched and searched but need to know the name of this one? That sits next to the coolant temp sensor in the housing.

Orite thanks

its your coolant temp sensor that links to your gauge only. any vauxhall dealer, lmf or autovaux will be able to get you a new one. needs to be a match to the car not the engine or the gauge may be wrong. most vauxhall ones are interchangeable though.

Just took my thermostat housing off to clean it. Bug want to replace the coolant temp sensor and the other thing which is this. What's it called? And can you get new one?
