I went through IIR a ordered a combo gms radiator, hoses, and 170* failsafe thermostate. Got a mushimoto rad which seems to be pretty good, don't like the drain plug though so I just pull off the bottom hose. The hoses are fine, but the t-stat failed open several times inside of the year warrenty, I got ahold of gimmick once and the guy on the other end picked up the phone like it was his cell.. I had to ask if I had the right number, then he said to pull it out and unlock the t-stat and it would be fine. It was, for about 2 days, I went to call him back again several times and they would not answer my calls or return my messages or pms, so I went to autozone and picked up the exact same 170* failsafe t-state for $17.. Like I got it out of the box, held them up together, exact same part. I will not deal with gimmick again.
