and the core, bypasses the oil around the cooler directly to the oil gallery in the cylinder block.
b. The by-pass valve should be removed, cleaned and reassembled whenever the cooler core is cleaned or
replaced. However, if required, the by-pass valve can be removed without removing the oil cooler.
