Evening all,

Does any one know:-

A. How to test the temp gauge once off the car to see if it is faulty?
B. What make/number the temperature gauge is and who stocks it. Nothing coming up from the usual suspects.
C. How to remove the aluminium bezzle and the TVR metal face of the dial. Just in case I have to swap them over on to a new unit.

I have put a new sender unit in. Cleaned the connectors on the sender unit. Checked all the fluids. removed the dash top and checked the connectors to the temp gauge, but it still sits on 55oC when warmed up and wont reach more than 60 full stop and sometimes it doesn't even register on the gauge. The gauge itself is now my last option.
It looks fairly similar to the oil gauge and they are only about £35 new.
Thanks in advance.

Thanks very much Paul.
I'm sure all that info will be appreciated by many more on here over the coming years.

That's what I'm afraid of!
My gauge had always been consistent if not 100% accurate. ie 80oC on the run and 85-90oC in traffic, but at least that would alert me if it suddenly shot up to 100oC. It is currently either not moving at all or at best 50-55oC on a run and maybe 60 in traffic.
There are some things you accept with TVR's but knowing the temp gauge is unreliable makes me increasingly paranoid!

Only me again!

I have just bought the following temp sender and spend half an hour getting access to the old one (what a pain in the ass that is!).



I was just about to remove the old one below when it became obvious that the one in my car is different to the replacement. Despite having the same spade connector for the temp sender wire to connect to, the sender unit itself appears to be about twice as long and included about a 1 inch brass fitting after the nut. Does the sender unit screw directly into the block, or does it screw into the brass fitting in the photo? I only ask because it appears that mine is one solid unit although I haven't tried to separate the 2 yet.
