Coolant System Malfunctions - Diagnosis –
The function of the coolant system is to maintain a
specified operating temperature of the engine. Some of
the heat generated by the engine is absorbed by the
coolant flowing through the passages in the cylinder block
and head. Then, heat is removed from the coolant as it
flows through the radiator. When you troubleshoot over
heating, remember that too much oil in the oil pan can
cause additional heat from friction when the rod journals
are submerged in oil.
Overfilling with oil raises the oil temperature which is
transferred to the coolant system at the oil cooler.
