Overhaul Information
Note
●
If the radiator cap is opened when the coolant temperature is above 100
℃
, the pressure of
coolant will drop and get boiled rapidly. The steam jet may cause danger and injury. Cover
the cap with a piece of rag after the coolant temperature goes down and open the cap slowly.
●
Inspection of coolant should be done after the coolant is fully cooled.
●
Coolant is toxic. Do not drink or splash it to skin, eyes or cloth.
— If coolant splashes in your eyes, thoroughly wash your eyes with water and consult a doctor.
— If coolant splashes on your clothes, quickly wash it away with water and then with soap and
water.
— If coolant is swallowed, induce vomit immediately and see a physician.
— Store the coolant properly and keep it away from reach of children.
●
Check radiator fins for mud block and/or damage. Correct the bent fins. Clean off the mud
With water and compressed air. Replace with a new one if the damaged fin area reached 20%.
●
The overhauling of the water pump can be done without removing the engine.
●
Add coolant through reservoir tank. Do not open the radiator cap except when disassembling the
cooling system for adding or drainage of coolant.
●
Do not stain the plastic parts with coolant. In case of any coolant stains, flush with water immediately
After disassembly of the cooling system, check the joints for leakage with a radiator cap tester
(available in the market)
