First cut around the hose about an inch from the end and then cut axially. After a few failed attempts at separating the two by pulling, I cut the hose. Remove the spring clamp from the existing hose/steel line interface in the return line.
#HOW TO INSTALL TRANSMISSION COOLER ZIP#
I then slipped a straw from a juice box over the wire, pulled out the wire and let the straw guide the zip line through. After a few failed attempts, I used a portion of a rubber coated wire hanger to establish a path through the radiator fins. The zip lines kept bending and wandering off instead of coming out of the other side of the radiator. I would recommend customizing a bracket instead of running the zip lines through the radiator fins. Since I just used a hand held tube bender and not a laser guided tube-bending machine, the bends weren’t perfect, but the tubing is malleable enough to make minor corrections by hand to get an approximate match between the two tubes.Īfter tightening the fittings and pressure testing, I mounted the cooler onto the radiator using the zip lines from the Hayden kit. This will enable you to match each bend and the tubes would run parallel around that radiator. When bending the tubing, instead of bending one tube completely and than the next, I recommend switching back and forth between tubes after each bend. Some minor cutting and bending was performed after this shot to achieve a suitable fit. Here is a pre-installation shot of the assembly. Compression fittings were used on the straight/cut ends and hose fitting at the flared ends. Since the ports on the transmission cooler were 10" apart, I cut the brake line into two pieces, 25" and 35". The lines are double flared at both ends and come with two flare nuts. The parts shop had 25”, 40”, and 60” lines to choose from. I found I needed an 8” and leg in front of the radiator and a 7” - 7.5” leg to get behind the radiator.

Here is a simplified sketch of common return line taps and routing: The tap I used is extremely easy to access and eliminates redundant lines, which can give a cluttered look.

Most auxiliary transmission cooler installs that I've read about tap into either the base of the tranny or the radiator. To minimize the length of tubing/hose I tapped in at the hose/steel interface on the return line just behind the bottom of the radiator. This gave me a clean look to the plumbing at a relatively low cost.Īuxiliary transmission coolers are more effective when routed in the return line of the transmission cooler rather than the feed line. I used the same materials as the stock lines, both reinforced rubber hose and steel line. Unfortunately, using braided steel hoses and aviation fittings, like Paul Jerkatis did, were way out of my budget. This wasn't really a bad thing, considering I thought that the rubber hose and band clamps looked out of place at the front on my Grand Prix GTP. Since I bought the cooler used, the hose and mounting hardware were not included. Installing a transmission cooler is a fairly easy project, leave it up to me to make it difficult.
