Hi guys,

Long story short, the old 4AC in my car has been intermittently overheating on longer drives. Not badly, but sometimes enough to get steam coming out of the overflow. Radiator seems fine, water pump and fan are working, the only thing I (and others who I've talked about it to) think that the thermostat is acting up.

My question is, can I rip the sucker out and just let the water flow all the time? Or should I just replace it as soon as possible?

Thanks lads.
