Fig. Fig. 1 When installing an oil cooler on a suitcase engine (type 3) make absolutely certain to use the three spacers shown (arrows), otherwise oil leakage will occur


CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

The Volkswagen oil cooler is mounted on the crankcase and is positioned in the path of the cooling air. The oil cooler in the type 1 engine can be removed with the engine in the car, but it is first necessary that the fan housing be removed. The oil cooler can be removed after the three oil cooler retaining nuts have been taken off. The gaskets should be removed along with the oil cooler and replaced with new ones when the cooler in installed. Before installation, the oil cooler should be checked for leaks at a pressure of 85 psi. If the cooler is found to leak, the oil pressure relief valve should also be checked. The studs and bracket on the cooler should be checked for tightness. See that the hollow ribs of the oil cooler do not touch one another. Clean the contact surfaces on the crankcase, install new gaskets, and attach the oil cooler. Tighten the retaining nuts. On the type 3 engine, be sure that a spacer ring is present between the crankcase and the cooler at each securing screw. If these rings are omitted, the seals may be squeezed too tightly, resulting in a stoppage of oil flow and consequent damage to the engine. The type 3 oil cooler is similar in design to that of the type 1 and 2, except that it lies horizontally cross-wise in the path of the air, while that of the other models is in a vertical position.
