REMOVING THE OIL COOLERDisassembly And Assembly
OIL COOLER DISASSEMBLY
1-Core assembly. 2-Pipe. 3-Water inlet pipe.1. Clean the tubes by passing a rod, having a diameter slightly smaller than the inside diameter of the tubes, through the tubes. If the tubes become damaged, the entire core assembly must be replaced.2. After cleaning, test with 80 to 100 PSI (5,6 to 7,0 kg/cm2) air pressure applied to the oil side of the core, and submerge entire core in water to be sure no leaks are in the core. Operating temperature water will give a more accurate test.3. Install in the reverse order of removal using new gaskets and seals if necessary.
