Derale D13504 Transmission Cooler Installation on a 1993 Chevy G-30 Van

Question:

Trans cooler came with instructions for an oil cooler. I am installing this transmission cooler on a 1993 Chevy G-30 van with A/C. Can you provide me with instructions and tips for this vehicle? Thank you.

There are not specific installation instructions when it comes to installing transmission coolers, but there are basic guidelines for installing one that are pretty universal.

The first step for installing this Derale Series 8000 Plate-Fin Transmission Cooler Kit, part # D13504, on your 1993 Chevy G-30 van with A/C is finding the best location for mounting the cooler.

If you mount the cooler in front of the radiator, you will get the most cooling efficiency from the cooler, whereas it will 40 percent less efficient if installed behind the radiator.

Next, you will need to route the transmission coolant lines to the cooler.

I would recommend that you run both your factory transmission cooler and this Derale Transmission Cooler, part # D13504.

I would run the output line from the factory cooler to the input of the # D13504 and then the output back to the transmission. If you route the coolers in that order you will optimize the cooling efficiency of the coolers.

If you do not have any already, you will also need a Derale Radiator Adapter Fittings for GM, part # D13018, so you would not have to cut or flare any metal lines.
