hello everybody , i'm new to all this forum stuff so be gentle . i need some advise from somebody , i'v just converted my na 90 to 200tdi and have noticed something not quite right , the engine runs fine , there is no smoke or anything else wrong but the temp gauge is reading high and i don't understand . i've flushed the rad and the engine , the water is not boiling and iv'e bled it . it is not using any water and iv'e changed the thermostat . iv'e spoken to a friend of mine and he said his doe's the same thing , has anybody heard of this before . i was wondering if the temp sender and the gauge are incompatable . any info would be greatly welcome .
