Testing - Oil Cooler Core
Caution: Do not reuse an oil cooler core after an engine
failure since there is not a practical method to clean the
cooler core. Metal particles which can circulate through
the lubricating system can remain in the cooler core and
can cause engine damage. Do not allow dirt or gasket
material to enter the oil passages when cleaning the oil
cooler and the cylinder block surface.
Install and clamp a short section of hose over either the
inlet or outlet transfer tube of the oil cooler. Install a plug
into the opposite end of the section of hose and install
the clamp.
