There are a number of factors that affect the cost of BMW coolant repairs, but the average costs are anywhere from $750 to $1,000. The parts themselves don’t cost much but do require more labor from mechanics, so they may charge more for this type of repair.
How does a BMW cooling system work?
On a BMW this is a mix of monoethylene glycol and distilled water. The water pump circulates the coolant and keeps the system pressurized. Starting from the pump, coolant enters the engine block and cylinder head to regulate internal temperatures.
Is it normal for BMW to lose coolant?
