Why is my car running hot at 3k rpm?
Because it’s run directly from the engine, if you’re at idle, the pump is running slower, and your coolant is flowing slower, so your engine temperature will go up slightly. At freeway speeds, when your car is running at 3K RPM, it’s working fastest, helping to funnel heat safely away from the engine and into the radiator.
Why is my Mercedes Benz 107 running hot?
Power flushing can correct this, or getting the radiator re-cored, or replacing it completely. Later models of the 107 used an aluminum core, with plastic reservoirs. The neck where the upper radiator hose connects can crack, causing a loss of pressure and coolant, and overheating of the engine.
What causes a car to run hot at idle?
A failing fan clutch can cause hot running conditions, especially at idle. Thermostat: Mounted on top of the engine, in the housing where the bottom radiator hose meets the engine.
What causes a Mercedes SL Class R129 to over heat?
A stuck close thermostat will create over heating and if it is stuck open the engine will run too cool. If your overheating and one coolant pipe is hot and the other is cold you may have a bad coolant pump. A clogged radiator can cause overheating and a broken hose can leave you stranded.

Why does my car run too hot without a cooling system?
The engine may be creating too much heat due to factors other than the cooling system. A proper air/fuel mixture will help your engine run cool and to its full potential. Most overheating issues related to air/fuel ratios are the result of a lean mixture, which causes the cylinders to run hotter.
