C14SE temp gauge sensor...
I basically need to replace this sensor as the top part that the spade connector fits onto (a bit like a drawing pin) has snapped off.
Do I need to do a full flush of the coolant when I change it (its on the back of the inlet manifold)
Cheers fr any advice!!
No you don't, you will loose some (not much) coolant when swapping them over. If you do it quickly the loss is minimal.
What I would say is after you've done it there will be some air in the system (the plug is used to bleed that engine) so run it with the expansion cap off for a few minutes.
