Default Aftermarket radiator and thermostat, word of caution

Jut wanted to let the community know about my experience with a certain aftermarket part that happened today. In early 2013 I hit a deer with my 2011 WRX and replaced some parts with aftermarket parts. I bought a Mishimoto radiator kit from Import Image Racing which included the aluminum radiator, Mishimoto hoses, and a "Gimmick Motorsports" thermostat (fitting name).

Fast forward to today. My car sat all last week because I was out of town and within a couple minutes from my house I noticed the car was almost up to the "red" on the water temp sensor. I limped it back home and it never went all the way into the red but was bouncing just below it. Turns out the thermostat stuck which caused the overheating and my mechanic said one of the seams on the radiator was blown out from the high pressure.

Just wanted to put this out there. It's my problem and I'll deal with it. The parts are over 2 years old, but I feel it's still good to get this stuff out in the open. I'd hope for over $300, a radiator could absorb such treatment and as for the stuck thermostat, I know it happens but damn.

Try and find a thermostat that is designed to open when it fails. GrimmSpeed used to sell a 160* thermostat that would fail in the open position, but it looks like they don't offer it anymore. That will avoid the problem.

Sorry to hear you experienced radiator failure! A stuck thermostat can certainly result in overheating which will raise coolant system pressure. We rarely see failures with our products, in fact we have a failure rate well below industry standard. This is rather unusual and we truly apologize for the inconvenience.

Have you contacted our customer service team in regards to obtaining a warranty replacement? If not, please submit a claim using the form below and we will be in-touch as soon as possible.

Again, I apologize for the inconvenience!
