Cooling System - Inspect

Usage:

3054 CHN

Cooling systems that are not regularly inspected are the cause for increased engine temperatures. Make a visual inspection of the cooling system before any tests are performed.

Check the coolant level in the cooling system.
Look for leaks in the system.
Note: A small amount of coolant leakage across the surface of the seal for the jacket water pump is normal. This leakage is required in order to provide lubrication for this type of seal. A hole is provided in the water pump housing in order to allow this coolant/seal lubricant to drain from the pump housing. Intermittent leakage of small amounts of coolant from this hole is not an indication of water pump seal failure.
Make sure that air flow through the engine room does not have a restriction.
Check the sea water strainer for debris. Remove any debris that is found.
Check the auxiliary water pump impeller. Ensure that the rubber impeller is in good condition.
Look for air or combustion gas in the cooling system.
Inspect the filler cap, and check the surface that seals the filler cap. This surface must be clean.
Look for large amounts of debris in the heat exchanger core. Look for large amounts of dirt on the engine. Remove the debris from the heat exchanger core and the engine.
