Transmission Fluid Cooler Recommendation for 2013 Toyota Sienna for Towing

Updated 03/29/2017 | Published 03/28/2017

Question:

I have a used 2013 Toyota Sienna with the 6 cylinder engine that does not have the Toyota OEM engine oil cooler. I want to tow a small pop up about 1,200 lbs loaded and looking for an aftermarket engine oil cooler. What do you recommend?

Nearly all vehicles on the road do not have engine oil coolers. The radiator and coolant does this job quite well. We have found that it is a VERY rare situation where an engine oil cooler is needed.

Most likely what you are looking for is a transmission fluid cooler as that is the common cooler associated with towing that people install. The most popular and best option will be the Derale # D13503 which measures 11" Wide x 8-3/4" tall x 7/8" and will do a great job to keep the fluid temps down.
