Thermal Transfer Products Oil Cooler 2" Taller Than Hayden 1260 Heavy Duty on 2040-parts.com
Corvallis, Oregon, US
This Thermal Transfer Products heat exchanger model DH-227-1-1 has been drained and capped but there's probably some residual Mobil 1 5W-30 oil left in it. I always ran this oil cooler downstream of a Fram HP4 filter so there should not be any debris inside. I threaded and silver soldered a brass 3/16" SAE male x 1/8" NPT male adapter into one of the manifolds for a drain (see picture 9.) This oil cooler is in excellent condition with the only concern being some slightly bent fins. I never had any problems using it with my old motor but my new motor needed more cooling capacity. This oil cooler comes with 4 shock mounting kits (pictures 10 through 12) that fit between the tubes, manifold, and fins.
