Starting a new thread to document the installation of a fuel cooler on my '94 K75RT.
Picked up this cooler on eBay. Looks pretty nice and has as many fins internally as you see on the outside. Has a pretty good volume that should give me about 40 seconds of residence time. Extruded aluminum body looks pretty snazzy and doesn't require any protection from stones and other debris.
Got it here: https://www.ebay.com/itm/10-Silver-Anodized-Dual-Pass-Transmission-Oil-Cooler-With-Fittings/302141681195?hash=item46590c2e2b:g:78YAAOSwUchaBCAf:rk:10
5/16" hose barbs: http://www.ebay.com/itm/331396623114?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
I am mounting the cooler horizontally below the radiator and in front of the cam chain cover. Hose connections will be on the left hand side. The mounting bracket will be bolted to the lower radiator bracket. I removed the existing flat head screws and the body nuts they screwed into. Replaced them with 25mm long 6mm bolts with fender washers, lock washers and nuts. The bracket goes in under the mounting tabs for the fan. Bolts go from the inside with the nuts outside.
Bracket is approximately 3mm thick stainless steel. Drawing with dimensions I used to follow.
