Caution
• Do not use alcohol- or methanol-based coolant.
• Use only soft (demineralized) water in the coolant
mixture.
1. Measure the coolant temperature and specific gravity with
a thermometer and a hydrometer.
2. Determine the coolant protection by referring to the graph
shown.
If the coolant protection is not proper, add water or coolant.

Caution
• Do not use alcohol- or methanol-based coolant.
• Use only soft (demineralized) water in the coolant
mixture.
1. Remove the radiator cap and loosen the drain plug.
2. Drain the coolant into a suitable container.
3. Flush the cooling system with water until all traces of color
are gone, then let the system drain completely.
4. Install the drain plug.
5. Fill with the proper amount and mixture of ethylene glycol-
based coolant by referring to the table above.
Coolant capacity:
13.5 liters (14.3 US qt, 11.9 Imp qt)
6. Run the engine, with the radiator cap removed, until the up-
per radiator hose is hot.
7. With the engine idling, add coolant to the radiator until it
reaches the bottom of the coolant inlet port.
