Transmission and Power Steering Cooler Recommendation for a 2005 Honda Odyssey

Expert Reply:

Since you are planning on buying a transmission cooler like the Derale Transmission Cooler, part # D13502, I would consider purchasing the Derale Combination Cooler Core, part # D15321. This cooler can be used for cooling both the transmission fluid and the power steering fluid on your vehicle in one compact package, see photo at right. You will need to measure to decide if you will be able to mount the transmission cooler first.

The dimensions of the Derale Combination Cooler Core are 13-15/16 inches wide x 10-1/4 inches tall x 3/4 inches deep. You will need enough space in front of the air conditioning condenser core to mount this cooler.

You would then need 4 of the Derale -8 AN fittings, item # D98202, and Derale High-Temperature Replacement Hose, item # D15700, along with Hose Clamps, item # D13008, for installation of the transmission cooler and power steering cooler.

You will also need to determine the inside diameter of the power steering return line and acquire 2 barbed fittings to match. The other side of these barbed fittings, going to the power steering side of the cooler, should be 1/2 inch diameter to match the inner diameter of the hose to the cooler.

There is a link to a video of a transmission cooler being installed on a similar vehicle as yours to the right that you might find informative.
