Cleaning The Cooling System
IMPORTANT: NEVER PUT COOLANT IN A HOT ENGINE: THE ENGINE
BLOCK OR CYLINDER HEADS CAN GET CRACKS BECAUSE OF THE
DIFFERENCE IN TEMPERATURE BETWEEN THE METAL AND THE COOLANT.
Clean the cooling system each time the coolant is changed. See the
Lubrication and Service Chart in this manual for recommended change
intervals. Clean the system as follows:
1. Remove the hose from to drain the coolant. Close the plug after the
system is empty.
2. Install a good type of radiator cleaner and fill the system with clean water.
Follow the instructions given with the radiator cleaner.
3. Remove the radiator cleaner solution. Flush the system with clean water.
4. Fill the cooling system with the coolant solution specified in this manual.
Install coolant system treatment (If required). See Coolant Solutions
in this manual for more information.
5. Check the hoses, radiator, pump and water manifold for leaks.
IMPORTANT: Never drain the coolant when the engine is hot.
NOTE: After the cooling system is completely filled, run the engine for
approximately five minutes to remove all air from the system. Check the
coolant level and add coolant if needed.
