Check Coolant Level

WARNING! Contents under pressure! Do not remove the cooling system cap when the engine is warm. Allow ample time for engine to cool before checking coolant level. Wear proper personal protective equipment when checking coolant. Failure to do so may result in severe or fatal burns.

This check applies to boats equipped with closed-cooling systems. When possible, perform check prior to starting engine. 1. Verify engine is OFF and engine safety starting switch is disconnected. Leave throttle/shift control lever in neutral. 2. Open engine compartment. Locate closed-cooling system tank installed on the engine. 3. Remove reservoir cap and check level. Verify coolant is at the GDI/-S series closed-cooling reservoir cap and tank

Pressure cap Fill neck

Allow room for expansion MPI-S series only closed-cooling reservoir cap and tank

MAX FILL line while the engine temperature is equal to ambient air temperature (COLD).

NOTICE: Do not fill tank beyond MAX FILL line while the engine is cold. When engine temperature increases, the coolant will expand.

4. If coolant level is below the MAX FILL line, add 5-year extended warranty propylene glycol coolant premixed 50/50 with water. The cooling system will take between 5.8 gal (22 L) and 6.8 gal (26 L) of coolant. 5. If tank is empty or nearly empty, notify an authorized Ilmor service center for immediate assistance as the engine cooling system will likely require purging. Purging should only be completed by a trained Ilmor service technician.

NOTICE: Maintain correct coolant level. Failure to maintain coolant at the proper level will cause potentially serious engine damage. The warranty does not cover engine damage due to overheating or any other cause associated with improper coolant levels.
