You blew a radiator up with boost?frontierguy25;1047501 said:I had a stocker and blew it up literally with a lot of hard boosting, but it was only 10psi. I replaced it with a new stock radiator and my car started to over heat and just get hot on long drives or a lot of traffic. I since then got a Koyo and it's been great, actually car seems to run too cool at times. I have a new stock fan clutch and fan to go with it.
