When you overheated the engine before when the radiator broke, you must have blown the head gasket. Have the radiator pressure tested to see if the engine cylinder gets coolant in to the cylinders. This will indicate a blown head gasket and possibly a cracked head. If you want to have this checked, a certified mechanic can come to your home or office to inspect the car’s loss of power and verify what the issue is.
