Specifications
Slowly pressurize the cooling system to 1.5 bar (150kPa) (22 psi), check the pressure over a 5 minute period. A
small pressure decay of approximately 0.15 bar (15 kPa) (1 psi) over the first minute is normal, as the air in the
expansion tank cools.
If the pressure continues to drop after the initial tolerance, there is a coolant leak.
Repeat the pressure test.
When the pressure over time remains constant, depressurize and remove the pressure pump and gauge.
Install the coolant expansion tank cap.
Tighten the bolts to 25 Nm (18 lb.ft).
