Default Re: 2004 H2 Engine Temp Gauge goes Nuts

Thanks for the help guys. I need to pick myself up one of those wonderful books!. I think it was my ECT sensor... I replace the ECT, thermostat and flushed with dexcool. So far no problems it's running at 190 and the needle is steady again no more jumping. I tested the thermostat and it opened at 190, It was flushed in 12/08 so Im guessing it was the ect. I don't know how to test the ect so Im only guessing that was it... Thanks again
