Supercharger Intercooler Pressure Testing
- WARNING:
Do not apply greater than 69 kPa (10 psi) to the supercharger intercooler, this may damage the charge air cooler and other internal components within the intercooler.
NOTE:The Supercharger Intercoolers and fasteners are not serviceable and are not to be tampered with or removed at any time for any reason.
Rotate the regulator knob (3) counterclockwise until stop to reduce pressure to 0 kPa (0 psi).
- Connect the J-46091 Charge Air Cooler Tester to a shop air source (1).
Install the EN-48974 Adapter Kit adapter hose (1), cap (2) and clamps (3) to the coolant inlet and outlet connections of the intercooler water manifold. Tighten the clamps until snug.
Install the J-46091 Charge Air Cooler Tester to the EN-48974 Adapter Kit adapter hose.
- Rotate the knob of the regulator slowly clockwise to increase pressure.
- With the intercooler pressurized to 69 kPa (10 psi) maximum, close the air inlet valve of the J-46091-1 .
- Inspect for a drop in air pressure on the gauge.
- If a drop in pressure is noted, inspect for leaks at the tool connections, the charge air coolers, service bleed ports, assembly plant fill port, and water manifold-to-charge air cooler seal locations.
- If no drop in pressure is noted, the intercooler can be installed onto the engine assembly.
The gauge value should not exceed 69 kPa (10 psi). Adjust the pressure regulator as required.
