So a while back, my temp gauge was going nuts (i'm not driving the car right now). For a while it would read really cold and then suddenly it would read "dangerously hot." Then it would return to normal opperation temperature. It was really cold outside when this was going on, so I think I busted my thermostat. So....should I avoid driving my car? I know I will need to replace the thermostat, but is there any danger of it damaging the water pump or any other parts of my engine? If you don't konw (and are too dumb to read my sig) I drive a 90 CRX HF with a JDM B16 sawp.
