Running Hot, Tried Almost Everything To Keep My Cool 200 1981

As a member of the "Cheap and Easy" approach, I would consider all the things that can give you the symptoms, and check things out.

1) The gauge lies. Other posts have this well covered.

2) Not enough coolant flow.
a. Low coolant lavel.
b. Thermostat failed in closed position.
c. Water pump not moving anough coolant.
d. Clogged hoses.
e. Clogged radiator.

3) Something else, like a bad head gasket. BTDT

My vote for quick and easy is the check for clogged radiator.

Add more cooling area. Do this by running the car heater at full hot full fan, all windows open if necessary, and watching the temp gauge. If it drops, it's a clogged radiator. Sorry.

Check for head gasket problem not otherwise apparent. Cold start, first thing in morning. Open hood, remove coolant reservoir cap, leave hood up. Watch the coolant reservoir opening while starting the engine. If coolant wells up and overflows out of reservoir, it's the head gasket. BTW I ran like that some years. As long as gauge stays OUT of the red.

Hope it's something cheap.

Good Luck,

Bob
