Engine Overheating?

This sound sliekt he fan clutch is out but to be sure this guide can help us find out what's going on and fix it

Please run down this guide and report back.

Check coolant level in radiator and add if needed make sure truck cool before opening rad cap
check and or replace thermostat

Hello, I'm Danny.

First thing you need to do is find the leak. If you don't have access to a coolant pressure tester most local auto parts have a tool loaner program and will rent you one. Here is a tutorial showing what is involved:

Basically it pressurizes the cooling system with the engine off and forces the coolant from where it's leaking. Let me know if you have any further questions on this.Hope this helps and thanks for using 2CarPros.

Danny-

The new thermostat could be bad-retest it-continues to overheat bleed the cooling system - see below that don't work have the tests done.

Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.

Block and Pressure tests

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.

Doesn't sound like either one. Sounds more like the water pump itself or a core plug near it. Cracked blocks are REAL rare. A cracked cylinder head is more likely and even that is not common. Head gaskets, when they leak outside the engine, will leak rather slowly, and often not at all until pressure builds up in the cooling system. You're overlooking something less serious.
