“Fluid Recommendations” topic for more
information on cooling system specifications. Do
not install the cooling system filler cap.

Start and run the engine at low idle. Increase the
engine rpm to 1500 rpm. Run the engine at high
idle for 1 minute in order to purge the air from the
cavities of the engine block. Stop the engine.
3.
Check the coolant level. Maintain the coolant level
within 13 mm (0.5 inch) below the bottom of the
pipe for filling. Maintain the coolant level within
13 mm (0.5 inch) to the proper level on the sight
glass.
4.
Clean the cooling system filler cap. Inspect the
gasket that is on the cooling system filler cap. If
the gasket that is on the cooling system filler cap is
damaged, discard the old filler cap and install a
new filler cap. If the gasket that is on the cooling
system filler cap is not damaged, perform a
pressure test. The correct pressure for the cooling
system filler cap is stamped on the face of the
cooling system filler cap. If the cooling system filler
cap does not retain the correct pressure, install a
new cooling system filler cap.
5.
Start the engine. Inspect the cooling system for
leaks and for proper operating temperature.
