INSPECTION
Intercooler Leak Test
4-TEC Supercharged Intercooled Engines
Perform intercooler leak test when engine looses performance, when there is white exhaust smoke or when temperature in exhaust system is to high.
WARNING
Let engine cool down prior to perform leak test. Direct contact with hot engine may result in skin burn.
NOTE: The inspection can be done while intercooler remains installed in air intake manifold.
Remove:
– seat
– outlet hose from exhaust manifold
– inlet hose from intercooler.
1 2
Otherwise, remove intercooler from manifold to spray soapy water on it. If air bubbles are present, replace the intercooler. Refer to procedures farther in this section.
Properly reinstall removed parts.
The distance between engine block and intercooler outlet hose must be 3 - 7 mm (0.12 - 0.27 in) otherwise the hose would scuff on the engine block.

Plug intercooler inlet nipple.
Install an adapter on the outlet hose to connect the leak test pump (P/N 529 021 800).
Pressurize the intercooler to 69 kPa (10 PSI) for a minimum of 10 minutes.
If there is a pressure drop, first spray hoses and adapters with a soapy solution to ensure they are not leaking.

Apply enough engine oil on ball bearing. Install ball bearing on supercharger shaft by using support plate (P/N 529 035 947) to hold bearing.
CAUTION: Ensure to position ball bearing against protrusion of support plate for the installation. This way, the installation pressure will be applied to the inner race and will not be transmitted to the bearing balls which would otherwise shorten the bearing life.
CAUTION: To install ball bearings and supercharger shaft always use a press, never use any beating force like a hammer.
