Intermittent overheating and hose bulged

Hello,

Is it overheating even after you refill it with coolant? A quick check you can do is, when the vehicle is cold, like first thing in the morning, is leave the radiator cap off and start the car and watch for bubbles coming out of the radiator. This indicates that combustion gases are getting into the coolant system from a head gasket problem. Here are a few more indications and tests of a bad head gasket. That hose may be blown up like that due to a head gasket problem as well.

What I mean is; does it over heat after you have filled it full with coolant? Or is it just overheating because it's running out of coolant? And like I said, when the car is cold, open the radiator cap and watch for any bubbles. That would indicate a bad head gasket. I wouldn't bother replacing the thermostat or anything until you figure out if you have a bad head gasket. If it has been overheated multiply times, most likely the head gasket went bad and possibly warped the cylinder head also.
