Engine Cooling System Inspection
Engine Cooling System InspectionWARNING:
In order to help avoid getting burned, do not remove radiator cap while engine and radiator are still hot. Scalding fluid and steam can gush out under pressure if cap is taken off too soon.
1) Check cooling system for leakage or damage.
2) Remove radiator cap.
3) Check coolant for proper level and freeze protection.
4) Check for check cooling system for leakage from cooling system using the following procedures:
a) Attach special tool to water filler, and then apply specified pressure to cooling system.
Special Tool
(A): 09918-78211
(B): 09918-78220
Cooling system holding pressure
123 kPa (1.3 kgf/cm2, 17.3 psi)
b) Check that cooling system holds the pressure.
If cooling system does not hold applied pressure, check cooling system for leakage.
5) Check radiator cap according to the following procedure.
a) Attach special tool to radiator cap (1), and then apply specified pressure.
NOTE:
Apply water or coolant to rubber seals before attaching special tool to radiator cap.
Special Tool
(A): 09918-78211
(B): 09918-78220
Radiator cap valve opening pressure
93 - 123 kPa (0.9 - 1.3 kgf/cm2, 13.4 - 17.3 psi)
b) If radiator cap valve opening pressure is out of specification, replace radiator cap.
6) Detach special tool and rinse off spilled coolant.
7) Install radiator cap on water filler.
