yea cause the more speed u get more wind blows through grill onto the radiator and engine cooling it more than if you just started it and let it idle..duh
but if u live in Australia as i do with 40 degrees c every day why dose it do it? is it an engine fault or an electrical fault
Could be low on coolant (leak somewhere) or the thermostat is faulty.
no way
Your temp. sensor might be faulty, or the wiring for the gauge, but 9 out of 10 times this indicates air in the cooling system. Check the overflow tank. When there is HOT coolant on the sensor, it pops up. When air hits the sensor, it dives down.
Low coolant level and possible coolant leak.
Replacing the gauge could be a costly job but it is seldom the gauge goes bad. More likely the temp gauge sending unit is at fault. Replacing the temp gauge sending unit would take less than 15 minutes.
A salamander is a cold blooded animal. So it simply follows the temperature change. Temperature goes down, its body temp goes down, Temp goes up its body temp goes up
Need to no more info, Year, engine size, what type of truck. It would help us answer it correctly. THANKS.
It goes to the temp gauge which is usually screwed in the head between the manifold on the drivers side, or into the thermost housing on the intake manifold.
the rise to 190 is normal. the reason for the drop in temp. is the cooling fan is doing its job, i wouldn't worry about that unless it overheates.
why doesn't my rpm gauge and temp gauge, fuel gauge not work
yes
