For those who want to keep the stock water-to-oil cooler
you must clock the sandwich plate so the fittings
are at about 10 o'clock position, pointing back and up towards the motor mount, making sure to not let the lines
make contact with the mount or alternator. Then tighten it down with the provided female to male stud which is a
1 inch (see picture below).
11. Now attach one of the lines to the upper fitting on the new Mocal sandwich plate and tighten it down, then do the
same with the other line. (it doesn't matter which line is which, the cooler will work in either flow direction).
12. Make sure the oil sandwich plate and both of the fittings and lines going to it are tight then go ahead and install
your new oil filter. Reinstall your oil drain plug at this time if you haven't already.
