I have a new mishimoto radiator I'm installing and I have both a mishimoto 160 and a ford 180 degree thermostat's. I live in so. California so it gets pretty hot in the summer. as we all know its kind of a bitch to change it with everything in the way so i only want to do this once. I'm a little worried that the 160 will be too cold for the engine to pass smog, and when that comes around I'll be 68 or older, so if i'm dead its a non issue, but if i'm still kicking I don't want to die under the car or pay someone to do it for me. anyone have a aftermarket radiator and a 160 and what temps do you run? thanks everyone, Dennis
