I need Help with overheating

[MjAllTheWay]

Ok like a month or 2 ago my heater control valve went bad and leaked most of my coolant out and my truck started to over heat so i noticed it and stopped driving changed that and now my truck will not stop over heating i can't find the problem i really need help.

It has an year old radiator 2 month old water pump and no thermostat at the moment thought it would run cooler with out one it dose jest not that much

No t-stat and/or cooler t-stat will not keep the truck from overheating, won't control max temps. It will net you lower MPG and a rich condition.

 

I'd be looking at either the pressure bottle/cap or the possibility that you installed the HCV wrong...and there is the ever present possibility that you never got all the air out of the system.

I can guarantee all air is out of system and no real way HCV can be put on wrong and i was thinking i should put the T stat back in but still can't find any reason its over heating.

The thermostat should be put back in. Without the thermostat the coolant circulates too fast which does not absorb enough heat from the engine and does not lose enough heat through the radiator.

 

I drove from Carson City, NV and had high temp problems and when I got back to WI. I found it had no thermostat. I put in a thermostat and it stays cool in stop and go traffic in 80+ weather.

I'd check the pressure bottle/cap first, then trace all the lines and make sure there are no leaks, then check out the radiator make sure it hasn't $#!& the bed. If all seems well maybe a flush will do you good? Sounds stupid but is there enough coolant in the system? We all have our moments.

how did you bleed the air?

And where did you add coolant to refill the system?

i couldnt figure out why my 88 was overheating all the time until i removed the ac radiator out. it was blocking the air....alot

just my two cents

Well i worked all day yesterday and found the problem something was clogging the radiator flushed it and it works great now thanks for all the help tho.
