Hi Guys
Just a quick call for help for my '96 4.0 HC Chimp. My Temp guage has started yo-yoing from about 60 to 80 C I'm guessing it's a dirty Contact, unless you know otherwise.
Anyway I know this sounds stupid, but I can't find the sender to check the contacts, could someone point me in the right direction.
Idiot/blindmans guides always appreciated.
Regards
Graham

When did you last check coolant levels? You can sometimes get strange temperature readings with an airlock in the system as the temp sender is designed to be immersed in liquid not hot air.
Go check it now just in case. Squeeze by hand some of the big robber hoses to check that there is coolant in them.
Warning: Do not go squeezing pipes with engine running and lose fingers in the fanbelt or when the engine is hot as this burns the figures.

Its scrwed into the top/front of the inlet manifold. Look just behind and to the left of the dizzy and you will be in the right area. The sensors screw directly into the casting, but there are several alternative positions on the casting so the exact position can vary from car to car. You will probably find two temp sensors, one with a nice latching connector is connected to the ECU and the other with a plain wire connected to a stud drives the temp gauge.
The sender or otter switch is on an alumimium canister behind the radiator lhs from drivers seat.Its about 12""high &4" across. The otter switch has a brass hexagonal nut on it pointing towards the engine. Only work on it when its cold -Otter switches cost about £9 new from TVR DEALERS.a SIMPLE IN AND OUT JOB BUT YOU`LL LOSS SOME COOLANT.
