Review on Hayden Automotive 402 Ultra-Cool Tube and Fin Transmission Cooler: Optimal Heat Dissipation for Superior Transmission Performance by Richard Cartner

Revainrating 5 out of 5

Wrong hose size for fittings

The barbs on the radiator are 3/8 but on the hose they are 11/32 (that's what the hose says). I had to heat the hose up a bit to get it to work at all, and after that I struggled to get the hose far enough to secure it with a clamp. I was afraid of damaging the thin aluminum ribs and lines. I recommend buying your own 3/8 hose and don't forget the 3/8 fittings as they are not included.

Pros
  • Ideal for a small house
Cons
  • Mostly ok but...
