Coolant: Testing and Inspection

Inspection 

LEVEL CHECK 

^

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

^

Adjust the engine coolant level as necessary.

LEAK CHECK 

^

To check for leaks, apply pressure to the cooling system with radiator cap tester (commercial service tool) and radiator cap tester adapter (SST).
Testing pressure: 157 kPa (1.6 kg/cm2, 23 psi) 

WARNING:  Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from
thermostat housing.
 

CAUTION:  Higher testing pressure than specified may cause radiator damage.

NOTE:  In a case engine coolant decreases, replenish radiator with engine coolant.

^

If anything is found, repair or replace damaged parts.
