●

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.

●

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.

●

Release air within route when refilling after draining engine coolant.

●

After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gasses for leakage.
