NOTE
The oil coolers on each side of the engine are removed in the same manner.
Removal of right coolers is described in the following instructions. Your
particular engine may have slightly different harness brackets from those
illustrated; however, they are mounted in a similar fashion and are removed
similarly.
Model AVDS-1790-2DR oil cooler removal and installation instructions are
similar to those described below except that this engine is not equipped with
a top-mounted engine wiring harness, nor is the oil sampling system on the
coolers; instead, a valve on the oil filter/damper housing serves the purpose.
REMOVAL

Step 1 opens an internal passage
allowing oil to drain from the
engine oil coolers into the oil pan.
1. Drain engine oil coolers.
a. Loosen oil drain valve (1) six complete
turns. Do not loosen oil drain valve
