You know how to fry steering pumps!
I guessed Mauler since hes the only person i know who said he hasnt had luck with a inline cooler. He called it more of a heat sink.
These coolers came to fruition after i realized i had a pile of rems that i pretty much wrote off. Fast forward to koh '09 when mass guy vapor locked. I read thru a thread where a guy though of using a howe p/s cooler for a fuel cooler. That flipped the lightswitch and i started making them and offering them to friends as a possible resolution or a preventative measure for a new car. As of now 1 is on a toyota with full hydro(tc pump) with no issues, 1 is on jason blantons fuel system and 2 on his steering( 1 gave him 3, he chose to run 2 on his steering, p pump). There are a few more out there but these are the only ones i know that are being used and they are working fine to my knowledge.
If they work, cool. Its a small simple unit. If they dont then oh well, Noone has every payed for one with the exception of hooking me up with something. Its my way of returning the favor.
For referance, That cooler is 2 x 12.
