Line Security - Aeroquip StartLite AN Fittings and HosesPosted in How To on January 1, 2012 0) (
We didn’t want to take any chances overheating the transmission in our “new” ’71 GMC project truck, so we went ahead and added a secondary external transmission cooler to keep the TH400 healthy and cool. One of the biggest mistakes we see people make is using a fuel hose to deliver transmission fluid to an oil cooler. It may seem like a good idea at first, but take a few trips out on the road on a hot day and the hose will swell-up and leak.
We used Aeroquip’s StartLite AN fittings and hoses to hook up a B&M external transmission cooler—in line with the factory heat exchanger in the radiator. Aeroquip’s reusable black-anodized StartLite AN fittings guarantee a leak-free fit while allowing us to reuse the fittings when we reconfigure the cooling system (nothing stays in place for too long on our trucks). We also ordered a box of the Startlite hose with a Kevlar-Nomex blend sheathing that is flame resistant, so it’s one less thing to fail in your rig.
