x2. Is the engine actually overheating or is the gauge indicating that it is overheating?

yes, sending unit was replaced, gauge seems to be reading properly. nothing erratic, just climbs slowly, when I shut off engine it pops and creaks a bit. I don't let it get to hot because If nothing is warped I don't need to create that. One last test today than I am giving up.
Keep in mind guys. I am not a mechanic but have a fair amount of experience working on vehicles. I am not implying I know alot but more so will try an fix them, lol, there's a difference. So far I have consulted with my buddy who is a jack of all trades, he has a friend that is a 20 years plus mechanic in Montgomery Illinois at a dealer. Another guy on this site has advised me also. They can only help me as best as I can explain a symptom. If I mis express a problem than they don't have much to go buy and bottom line, I am to blame for nit fixing the thing.
So far I have replaced the stat with 2 different stats, sending unit, flushed Rad which was clear (undoubtedly), flushed heat core which was clear, replaced intake gasket, replaced head gaskets, inspected hoses and all are fine (100% sure). When I filled the system last night after replacing the head gaskets, the system took only 7.5 quarts. The system holds 13. I had some in the block and am guessing roughly 3 quarts in the block. Seems to me a have air locking preventing me from filling the system. I pulled the intake sending unit and whala, it started hissing as I was unscrewing it and i thought to myself that I finally founds the culprit. The intake was empty and the system took another gallon. WOW right? wrong! Did the same exact thing. This was my lowest point of working on this truck. I've got days involved on this job and cannot seems to figure it out. I am trying one last things. The first post on this thread was to drill a small hole in the stat flange to allow air to pass. It is possible I have a lock at the stat. This morning I am hopeful as I have been many morning before going out to work on the truck.
I am kinda like a dog with a bad owner. No matter how bad I feel about the truck treating me I still wake up wag my tail with hope that today will be a good one. So now, I am going out to drain another gallon on green on the garage floor, just kidding. Drill a small hole in the stat and try again ( waggin my tail). If this don't work I'm friggin cutting both arms off and going on disability, well, maybe not but I'd like to. Wish me luck fellows, I'm going in!!!!! waggin my tail!!!!

I'm typing in red becasue my tail aint just a waggin, my whole hind end is movin.
This just in, special bulletin
"THE TRUCK IS FIXED"
I just put a few hundred buck and 32 hrs of work into a truck that had an air lock, that's right people, an AIR LOCK, I drilled a small hole just like the first poster said and as I started to fill the rad again I noticed a huge amount of air purging out of the system, my tail started waggin big time. I got in and I had some heat at the heater already, I really started waggin so much I nearly fell down. I took er for a ride and it just stayed where they always stay. Excellent heat now also. OMG am I ever a looser for doing all I did. Do you realize what is involved to dio what I did. The entire front of the motor was off, (alternator and power steering, opposite side pulley assembly, shroud, radiator, trans lines, rad hoses, fan, fan clutch, water pump, distributor and wires, intake, heads, exhaust manifolds, drop y pipe x2 nearly
Thanks guys for all the advise, especially those who were persistant with the bleeding of the air out of the coolent system, you guys were right and I was wrong. What a learning experience. I did say at some point I thought there was a circulation problem but couldnt get past how

Im not sure who your buddy is, but Ive always tested system flow performance by filling with water and letting it spray all over the place. Right off the bat, it sounded like you were air locked since the pump wasnt pumping. Glad you found the problem, I still dont understand why the system bleeder didnt take care of it. Oh well, get some JB weld out and fill that little hole and you're all set! Never give up!

I was just going to ask...how did you fill the hole?

I did that, I pulled the heater hose off the water pump and nothing, if there is an air lock in the system, the water cannot flow so that is why this test doesn't work at least with this vehicle. The pump pumps as long as the belt is turning it. The pump has small impeller, not what I thought it would have, I can easily see how it can spin and still not pump. There is no system bleeder. The Montgomery mechanic says they always pulled the intake manifold temp sensor because it is easy to get to and just as high up as the stat, that's how they bleed the air out. Now at the same time the GM AC stat probably have the small hole in it. I bought 2 different stats, one from Car quest and the other from NAPA. Neither had a small bleeder hole, it does now and what a difference they make. If I would have got the stat from a dealer I bet it would have been fine. The hole is the stat flange can stay there. It probably will slow the warm up slightly but I am okay with that.
I think we are saying the same thing. I was saying that the fact that the pump was not pumping would lead me personally to believe the system was air locked. I have had many a water pump spraying me inside of an engine compartment testing the pump, so the fact that yours wasn't pumping would have lead me to believe air lock. Anyways, glad you got your truck fixed!

you don't need to fill the hole because it is in the thermostat itself, not the stat housing. The air just flows through the stat and through the system, as long as you have the radiator cap off the air bubbles can pop right out the cap. That was happening to some degree, as much as it could and that is why I thought I was leaking compression into the cooling system because I was seeing bubbles when I thought I could say the system had no air in it (burped.) Obviously I didn't know the system was locked because I thought I did burp it good enough.

I see what your saying. Thanks, I am glad to
I told you in post 13 to go get a thermostat from the dealer. I guess I should have said something about the bleed. Went thru the same thing with a van. New Rad, hoses aftermarket thermostat. Ran hotter afterall the new parts. Went and got the correct stat from Ford and all was perfect. Glad it's fixed.

you had it right buddy, the after market stats are for sure different, that hole makes a world of difference.
where the heck did you buy this truck any ways? lol
