Hoping some of you knowledgeable fellows can help me with an issue I'm having on my new truck. First a little bit of history.
Purchased the truck in Nashville, TN last week. Its a 1987 F350 crewcab dually 6.9 with c6 automatic and ATS Turbo model H730441. Doesn't appear to be wastegated.
While driving it home to Kansas, I noticed that the engine wasn't getting up to temperature (yes I know the factory gauges can't be relied on) and every time I would come off the highway to lower speeds it would puke coolant out of the overflow tank. I didn't have any issues while maintaining highway speeds. I figured it probably didn't have a thermostat and I didn't have any proper tools with me to check the actual temperature. Just kept filling up the radiator and overflow with water for the remainder of the trip. I also couldn't get the truck to start in the mornings without very carefully using just a slight burst of starting fluid, brushed that off as bad glow plugs. Also noticed my pyrometer is not working, its a ISSPRO meter. Not sure how to diagnose and repair that?
Made it home with no issues. Went ahead and flushed out the cooling system, removing the block drains and all. Installed new motorcraft thermostat (thermostat was indeed missing) along with motorcraft glow plugs and a new 13 lb radiator cap. I do have the little ball in the thermostat housing, cleaned it up and moves freely. Still refused to start, diagnosed and found burnt connector on passenger side near starting solenoid. Bypassed and spliced the 2 yellow wires to the appropriate wires. Voila, started right up!
Now it pukes coolant out of the overflow all the time when its heated up causing it to overheat. I'm deaf so no idea if the ball in the thermostat housing is clinking but have no reason to believe it would not be since I cleaned it up and installed it properly. I did the cold start and shut off after 30 seconds and I am getting pressure in the radiator, air pushes out when I removed the radiator cap. Bypassed the heater core, simply to remove a variable in diagnostics. Air passes through the overflow hose freely. Installed the overflow hose into a water jug with the radiator cap on and started up the engine. After 7 minutes, air bubbles start to show up in the water jug. Temperature at that time is 110 at the CTS and 72 at the thermostat using a digital temperature gun. Blown headgasket?? I'm not losing coolant anywhere except the overflow tank. No oil in the cooling system and no water in the engine crankcase.
Any and all replies, opinions and judgements are welcome! Thank you all in advance!
