Certain engine faults, such as a leaking head gasket(s) or poor engine running condition can cause overheating. If bubbles are coming up in the coolant, you should test for exhaust in the coolant. If present, that would suggest either a leaking head gasket or a crack in the block or head(s). The more common causes of overheating include low coolant level, a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an engine overheating diagnostic and the responding certified mechanic will get this resolved for you.
