need to replace my thermostat i think as when im driving the gauge is sitting at about 80 sometimes lower and higher when im slower moving.
iv been reading into it and understand it apart from some people seem to buy the whole thing with the metal housing but i understand you can just buy the insert?? i know there is a how to but it still gets me as to how easy this is to just change over the internals if lots are buying the whole thing.
it also mentions about using a silicon but is this in the case that you havnt got a new replacement gasket???
sorry if it seems a silly question to some but i thought id check before i start pulling it apart and break it...
