Engine Runs Hot
WARNING:
Never remove the radiator cap under any condition while
the engine is operating. Failure to follow these instructions could result in
damage to the cooling system, engine, or cause personal injury.
WARNING:
The bilge can accumulate explosive fumes. The bilge fan
will evacuate the fumes. The bilge pump must be run for a minimum of 10
minutes prior to cranking the engine.
CAUTION:
DO NOT add coolant to any engine that has become
overheated until the engine cools. Adding coolant to an extremely hot
engine can result in a cracked block or cylinder head.
The following items may cause the engine to overheat.
• Low coolant level
• Loose or broken belt
• Inoperative thermostat
• Inoperative water pump – seawater or circulation or sand trap
• Clogged inlet strainer – seawater or circulation from jet drive
• Clogged heat exchanger tube(s)
• Low oil level
If you perform the Pre-Operational and Operation Procedures as outlined, you
will find that these items are subsequently checked on a regular basis. The habit
of performing the Pre-Operational and Operational procedures is your best
method of ensuring all steps are followed periodically.
