To clean and to inspect Operation 12-33
To clean
1 Thoroughly clean the flange face of the intercooler top cover and the induction manifold with an approved
detergent solution.
Warning! Do not allow compressed air to contact your skin, if compressed air enters your skin obtain medical
help immediately.
Caution: Do not clean the tube stack in a caustic solution.
2 Soak the fins of the tube stack in an approved detergent degreasing fluid. Allow the excess fluid to drain off
and dry the fins with low pressure compressed air.
3 Flush the tube stack through the outlet connection, in the opposite direction of coolant flow, with clean water.
4 Thoroughly clean the internal and external surfaces of the intercooler casing, with an approved detergent
solution. It is important that the seats for the "O" rings are thoroughly cleaned.
To inspect
1 Check the casing of the intercooler for cracks or distortion, especially the flange faces which must be flat to
prevent leakage.
2 Check the tube stack for signs of leakage, cracks, damaged fins or damaged hose connections. If the tube
stack is damaged or the tubes are restricted the tube stack must be renewed.
