Initial Inspection and Diagnostic Overview

LEVEL CHECK





^ Check if the engine coolant reservoir tank level is within MIN to MAX level when engine is cool.
^ Adjust engine coolant level as necessary.

CHECKING COOLING SYSTEM FOR LEAKS

WARNING: Never remove the radiator or reservoir cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator or reservoir.





^ To check for leakage, apply pressure to the cooling system at the reservoir filler neck using suitable tool and Tool.
Tool number: EG17650301 (J-33984-A)
Leakage test pressure: 137 kPa (1.4 kg/cm, 20 psi)

CAUTION: Higher pressure than specified may cause radiator damage.

NOTE: In case that engine coolant decreases, replenish cooling system with engine coolant.

^ If any concerns are found, repair or replace damaged parts.

CHECKING RESERVOIR CAP





^ Check reservoir cap relief pressure using suitable tool and Tool.
Tool number: EG17650301 (J-33984-A)
Standard: 95 - 125 kPa (0.97 - 1.28 kg/cm2, 14 - 18 psi)

NOTE: Apply engine coolant to the cap seal.

^ Replace the reservoir cap if there is any damage in the negative-pressure valve, or if the open-valve pressure is outside of the limit.

CHECKING RADIATOR CAP
Inspect the radiator cap.

NOTE: Thoroughly wipe out the radiator filler neck to remove any waxy residue or foreign material.

^ Replace the cap if the metal plunger cannot be seen around the edge of the black rubber gasket.
^ Replace the cap if deposits of waxy residue or other foreign material are on the black rubber gasket or the metal retainer.
