Ok so my truck overheated twards the end of last summer an i changed the Stat but it was getting cooler so it stopped overheating, I thought i had it fixed but Today i found out i didnt. It cant be the water pump because it only over heats when its hot out. Im thinking cloged Radiator.
Does this meen i have to replace the Radiator? or can i fix it.

 

I would say
1. Disconnect your radiator and flush it with a garden hose. Reconnect all hoses and refill to spec.
2. Check the thermostat

Try that first. Do you have an efan?

 

not yet and its only the 195 degree stat. My friend worked at an autostore and he gave me the sts for free so i couldnt complain lol

 

how do you no if the stat is bad? can you tell by just looking at it

 

i had the same problem only whenthe a.c. is on though and only a couple times on the high way only it was a very hot day out +35 ish

 

Oh what was the problem

 

lol i dunno it just kinda corrected it self i just chimed in so i dont loose the thread cause i would like to know what to look for sorry not trying to steal your thread buddy

 

Oh its cool idc lol... Im gana flush out my radiaotr next time i get a chance i dont have much time since i have work right after school. Looks like ill be driving with the windows down and the heat goin hahah

 

lol on the plus side i dunno how the weather is there but i still need my heat in the mornings and evenings im sure some one will chimein i know im due for a coolant flush

 

I would start with making sure your clutch fan is spinning, I mean SPINNING, not just the slow spin from the centriphical force of the pulley spinning. Then i would do a flush with a garden hose.
The only proper ways to tell if the thermostat is broke is to take it out and run the truck with out the thermostat in place. If it runs hot its not the problem. You can also warm some water up on the stove to about 200 degrees (use a thermometer) and see if it opens.
