check the fan clutch
Has the rad ever been flushed? Try that if there is no indication of water pump failure (leaking or venting coolant from pump.)
YEs it should!! the tech is trained to accomplish all that > when a car comes in they cannot let the car leave if there is still something wrong like the radiator not being flushed after changing the manifold gasket, your tech was probably hoping that you would pay the extra cost.
more than likely you need a new radiator for it, when you install it back flush the engine.
So, it still has the old thermostat right? Maybe it needs a new one or maybe it got put in upside down. It's easy to do.
Make sure connections are on tight.
Have flushed complete cooling system replaced water pump radiator thermostat clutch fan added 2gal straight anti freeze then filled to capacity with water and truck is still over heating. What else could possibly be wrong
you must be a wierdo.stupid.
A thermostat is one cause of over heating engines.The "Related Question" below lists a few other suspects to investigate that can also contribute to overheating.
cooling system needs flushed out and a new thermostat installed, also if the radiator is still original it probably needs replaced or rodded out.

System airbound? Coolant level? Temperature control cable?
It could be a clogged radiator or cracked head or bad head gasket.
could be the water pump That is a typical symptom of an air lock in the cooling system
Guess that wasn't it, huh? Sorry, no offense intended. Is the coolant full? is the thermostat working, heater core plugged? Need more info to go further, what else has been replaced? why did you replace the heater control valve? based on what?
water pump
check your fan clutch if its weak it will overheat
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
