I was removing the thermostat since it was in bad shape. caused my car to overheat. but also the o-ring on the thermostat housing need to be changed to but i cant seem to get it off...i took off the screws and it move but theres this metal pipe connected to it and it dont see any way of taking it off lol. So anybody got any idea how?
