If your level sensor gives a low level warning (true or not), it may peg the guage on some model years. My '85 did this when I was bleeding the system after installing a new engine. The level dropped low enough to cause the light to blink and the guage just pegged indicating a high temperature. In fact, there was still coolant in the tank, it had just dropped below the probe level. When you go from higher rpms to idle, the coolant level will rise some in the expansion tank. This is why your guage read normally again after idling. It sounds to me like you may still have some air in the system. More than likely, it is not running that hot, it is just the low level pegging the guage. I had good luck topping off through the radiator bleed hole using a squeeze bottle. Bleeding the system is trickier when the whole system has been emptied after an engine replacement. Jay '85 Westy

Hi, yesterday SWMBO told me that Paddlevan 84 1.9 l was showing as running hot. Last night I went through the bleeding procedure and every thing appeared to be fine but after it warmed up the gauge stayed to the right.When i stopped and it idled down the guage dropped to the left... So far no apparent coolant loss . no coolant trail . The system appears to be holding pressure. I am using the orange dexcool..Should I head for the hills or replace the thermostat???? Any other suggestions
