Inspection
Reservoir Tank Cap Testing
1.
Remove the reservoir tank cap, wet its seal with engine coolant, and then install it on a pressure tester.
2.
Apply a pressure of 93.16-122.58kPa (0.95-1.25kgf/cm², 13.51-17.78psi).
3.
Check for a drop in pressure.
4.
If the pressure drops, replace the cap.
Radiator Leakage Test
1.
Wait until engine is cool, then carefully remove the reservoir tank cap and fill the reservoir tank with engine coolant, then install it on the pressure tester.
2.
Apply a pressure tester to the radiator and apply a pressure of 93.16-122.58kPa (0.95-1.25kgf/cm², 13.51-17.78psi).
3.
