Low temperature circuit
Shown: Model 240
The charge air coolers are connected to a separate coolant circuit with a low temperature cooler (110/11) and an electrical charge air cooler circulation pump (M44). The air that is heated during the charging process dissipates the heat to the coolant flowing through the charge air cooler.
The coolant is subsequently cooled in the low temperature cooler and then pumped back to the charge air coolers from the charge air cooler circulation pump.
The function of the charge air cooler is dependent crucially from the air bubble free filling of the low temperature cooling circuit. A special tool (vacuum pump) is required for filling and work instructions must be followed carefully.
Open the cap at the low temperature coolant circuit only when the charge air temperature is increased (power shortage) and when the engine is cold. The coolant must reach up to the cap.
