Overheating
2 Answers
No need to change the thermostat again, its just been changed. If you overheated it a lot you may have done other damage to the car so you'll need to sort that out. If the car still runs, there is most likely air trapped in the system which needs to be bled out so the coolant will circulate and cool properly. There is a bleeder valve near the thermostat that is used for that. If that doesn't work try draining it and refilling it with the car facing uphill. Sometimes that helps bring the air up to the top where it can be released using the bleeder valve.
