Checking coolant leaks
1.
After the coolant temperature drops below 38°C
loosen the radiator cap.
2.
Check that the coolant level reaches filler neck.
3.
Install the radiator cap tester to the radiator filler
neck and apply a pressure of 1.4kg/cm2 .
While maintaining it for 2 minutes, check the radiator,
hose, and connecting part for leak.
CAUTION
Because the coolant in the radiator is too hot,
never open the cap when it hot, or injury may
occur due to an outburst of hot water.
Dry out the inspection part.
When removing the tester, take care not to spill
the coolant.
When removing/installing the tester as well as
testing, take care not to deform the filler neck.
4.
Replace parts if leak is detected.
Specific gravity test
1.
Measure specific gravity of the coolant using a
hydrometer.
2.
After measuring the coolant temperature,
calculate specific gravity using the following table.
Relation between Coolant concentration and Specific Gravity
