3. CHECKS & ADJUSTMENT
3-16
When the coolant level is below the LOWER limit,
remove reservoir tank cap and add coolant till upper limit.
(Add coolant or diluted original liquid).
Recommended coolant: XYPOWER coolant
Standard density: 50%
( Freezing temperature of coolant varies
according to the different mixture ratio.
Adjust the mixture ratio according to
the
lowest temperature in the place where the
vehicle is used.)
If the coolant reduces very fast, check if there
is any leakage. The cooling system may be mixed
with air when there is no coolant in the reservoir
tank and the air should be discharged before
adding coolant.
Coolant Leakage
Check radiator hose, water pump, water pipes
and joints for leakage.
In case of any leakage, disassemble and do
further check. (Refer to Chapter 4)
Check the radiator hose for aging, damages or cracks.
The rubber hose will naturally get aged after a period of service
time. The aged hose may get cracked when the cooling system
is heated. Nip the hose with fingers and check if there are any
tiny cracks.
In case of any abnormal, replace with a new hose.
Check the clamps of the coolant pipes and hose.
Tighten properly in case of any looseness.
Check radiator fins for mud and dust clog or damage.
Correct the bent fins; clean the mud with water and
Compressed air. When the damaged area of the
radiator fin is over 20%, replace with a new
radiator.
Check Water Temperature Gauge
When engine is not working, the water temperature should be in
the “0” position. Start the engine to check if the indicator works. If
the indicator is not working, do the maintenance in time.
