Question:
2016 Honda Pilot AWD towing a 3500lb camper. Purchased an electric brake controller from you. Installation was perfect! Also purchased a series 9000 transmission cooler to be installed. Should I also purchase an engine oil cooler? Can I install next to transmission cooler without sacrificing radiator cooling. Thank you.

Hey Brian, thanks for reaching out - I'm glad the brake controller is working out for you!
The Derale Series 9000 Plate-Fin Transmission Cooler Kit # D13611 you got will be sufficient to keep your 2016 Pilot from overheating, but I do understand the desire to operate at cooler temps so if you wanted to also install an oil cooler I definitely get it.
As long as you use a relatively small oil cooler, like the Derale # D15602, the restricting airflow won't be a problem. For the best of both worlds we have kits like the Derale Electra-Cool Combo Engine and Transmission Cooler Assembly w/ Fan # D15200 which cools both of the things you're wanting to cool and it has a fan so it can be mounted anywhere you have room - but you already have the transmission cooler so it wouldn't make sense to get this.
