Flushing the Cooling System
Do not allow the cooling system to freeze during the cleaning procedure,
as the system is not under the protection of antifreeze. Do not flush the
cooling system when ambient temperatures are at or below freezing.
1. Open the surge tank cap and bleed screw on the upper coolant pipe. The surge tank cap and bleed
screw should remain open during the flushing process.
2. Slowly refill the cooling system with clean, soft water and a good cooling system cleaner. If the
engine is warm, fill slowly.
3. When system appears to be full, wait 2 to 3 minutes to allow the air to be vented, then top off the
water/cleaner solution.
4. Turn the heater temperature switch to “HIGH” to allow maximum coolant flow through the
heater core. The fan does not have to be on.
5. Start and run the engine for the time period recommended by the manufacturer of the cooling
system cleaner.
6. Stop the engine and allow it to cool.
7. With the engine cool, drain the cooling system completely.
8. Refill the cooling system with clean, soft water and let the engine run for 15 minutes.
9. Stop the engine and allow it to cool.
10. With the engine cool, drain the cleaner residue from the cooling system following the above in-
structions on “Draining the Cooling System.” If the water being drained is still dirty, the system
must be flushed again until the water is clean.
11. Proceed to the “Coolant Fill Procedure” once the cooling system is clean.
