exhaust manifold reconnected everything
correctly. Started right up. Right after I started it I
noticed coolant temperature on dash reads hight. I
request a coolant temperature sensor. Still the

same reading hight indicating overheating. Can

Double check your work. Make sure the wiring for the coolant temperature sensor is not touching the hot exhaust manifold. If it is the insulation has burned off and the bare wire is touching the exhaust manifold and creating a short. This will drive the temperature gauge to hot and make the temperature light come on immediately when you start the engine. Hope that helps! Jim
