wierd cooling issue any suggestions

i replaced thermostat water pump is good truck warms up great drives great besides shitty carb ....but once it warms up it runs hot almost overheating... if i turn it off and wait five minutes its cooled off and does the same ....i think my clutch fan sucks and advise?

Yes be sure to make sure the clutch fan works, if it is engaugeing at temp then maybe the rad is junk, and the veins are full of junnk.

if the fan is turning then the motor is geting air, sounds like the rad,you sure the water pump is good man

water pump is good i put a flex fan on it its better but it still runs hot not over heating but hot... i am going to get a 160 degree thermostat to see if it makes it run a little cooler

one way to check the thermostat is to remove it completely and run the truck just dont leave it out permanently or it will never warm up in winter

If it overheats while driving it has nothing to do with the fan or the clutch on the fan as the fan is only there to keep it cool while you're stopped (at lights or stuck in traffic).
With the thermostat I wouldn't remove it as that will cause overheating sometimes too, (and it takes forever to warm up), the best thing to do if you do want to mess with the thermostat is pull it out, smash out the centre part and put the casing back in, this slows down the water flow enough to stop overheating and will tell you if it is indeed that causing you your issues.

If it was me I would get a new thermostat, top and bottom radiator hose, bypass hose, radiator flush and antifreeze/rust inhibitor and start again.
Put your radiator flush in, run it 'till warm then wait 'till it's cool and drain, change your hoses, (but do not put onto the radiator yet), remove thermostat and leave the housing off for now, hook up your garden hose to the heater inlet hose and turn it on SLOWLY and flush out all the gunk that's built up inside,do this to the bypass hose too (if you have one), reattach the heater and bypass hose then flush from the thermostat housing back down through the bottom radiator hose, insert new thermostat (remembering to put the tab at the top) and put housing back on, flush the radiator from the top down and once clean reattach the bottom radiator hose.
This should remove pretty much all the crud inside your engine, refill and purge air from your system and you should be good to go.
P.S. You did bleed out all the air after you changed the pump didn't you?

another thing i forgot to mention is to clean out the radiator cooling fins. this usually works on the big trucks ( i am a heavy diesel mechanic) whith the engine and rad cold tahe a hose and wash the rad out from top to bottom until you can see through all the fins this sometimes takes a while. be sure to point the water directly at the rad not from the side. if yoju do bend the fins take a flat screwdriver and gently bend them back. hope this helps.

I just went through the same thing it ended up being my radiator put a new one in and it runs great now no over heating or even close to it
