Water temp crisis, please suggestions

[fkn16v]

Has this happened to anyone else before.

Possible Reasons?? how to fix??

Had a Autogauge watertemp gauge installed, was working perfect for 12-16mths something like that , then all of a sudden stopped reading correct, would only go up too 50deg c .

Not "read correct" and stop at 50, when water was warm the needle hadnt moved. So its delayed type of thing.

Ok its a 10$ ebay heap of shit, so i thought might aswell shell out on a brand name item.

Enter Speco sport comp , some problem .

I got a new gauge and sendor send to me just incase, i know these things can be sensitive and dont like being dropped . Still same problem with new stuff

HMMM what now, new gauge and new sendor, all new wires (too eliminate faulty wires) excact same thing.

Ive sinse been able to find out that the gauge always reads 30deg less then it should. Water at 80 then gauge says 50, water at 90 then gauge reads 60.

Any ideas people, ive tried all locigal theories but dont let that stop you throwing ideas at me. Ill try just about anything once or twice.

Any help id greatly appreciated as always.

I might post this on a few forums, more responses that way.
