I want to add a trans cooler and have a question on what type cooler would work best for my set-up. 390, C6, 8.8 rear. I wanted to mount the cooler behind the battery box under the cab outside the frame rail, (56 f100). Will a fan be needed? can I use a frame rail cooler and not use the fan?
If you get one from a yard look at it real close. They pull these and let them seat around, Next thing you know the bugs have made a home in it. Also they need to be flushed before use, Just to be sure it is clean.
As you will note in the installation instructions, the additional cooler was installed in front of all other radiant coolers for maximum cooling efficiency. I had concerns that the additional cooler would keep the transmission temps too low, but, mostly because of the mounting location (cooler partial covered from direct airflow behind bumper), this concern turned out to be unfounded. I also integrated the electric fan I initially installed into the installation to cover those times when increased airflow is necessary to maximize cooling efficiency. The addition of the cooler did not measurably affect my non-towing temps (140 -145 degrees). My normal Fifth Wheel towing temps (see above) have been reduced by 15-30 degrees and have yet to exceed 145 degrees. Engaging the electrical fan at highway speeds had no measurable affect, however, on long steep grades at slow speed and when jockeying heavy loads into tight parking spaces, the fan assist has kept temperatures that use to range above 200 degrees to now read well below 160 degrees.
