COOLING SYSTEM 4-9
Coolant
Pressure Testing
•
Remove the radiator cap, and install a cooling system
pressure tester [A] on the radiator filler neck.
NOTE
○
Wet the cap sealing surfaces with water or coolant to
prevent pressure leakage.
•
Build up pressure in the system carefully until the pres-
sure reaches 123 kPa (1.25 kgf/cm², 18 psi).
CAUTION
During pressure testing, do not exceed the pres-
sure for w hich the system is designed. The maxi-
mum pressure is 123 kPa (1.25 kgf/cm², 18 psi).
•
Watch the gauge for at least 6 seconds.
If the pressure holds steady, the system is alright.
If the pressure drops soon, check for leaks.
