Sounds like you could have a blown head gasket or craccked cylinder heads, the loss of coolant could have made it into your cylinders causing it to hydro lock which would explain the trying to start and have it come to a screeching haultHey everyone,
So I recently purchased a 2006 F350 6.0 with approximately 154K. I am new to diesels and only know what I have read or from youtube videos so yeah... First day the degas tank cracked and leaked coolant all over my driveway. Purchased a new aluminum Mishimoto tank. Figured I'd also change the radiator hoses to Mishimoto while I was at it and install their coolant filter. While I was doing that I replaced the coolant temp sensor and the intake manifold air temp sensor. Also did the blue spring upgrade. Then flushed the coolant (kinda nasty looking) and put in new 50/50 using Ford Gold and Distilled Water. Put everything back together and the truck seemed to run good.
At this point I know that I have an oil cooler issue and need that serviced or more than likely just replaced all together.
- AC is not working so not sure what's causing that.
- took truck on two hour drive relying on only dash temp indicators. Ran good, no apparent issues, no smoke, etc. Just a hot drive w/out AC.
- after that drive I noticed coolant all over new reservoir. Level was high, above Full for some reason
- hooked up a bluetooth monitor to OBDII port. Watched temps the next two days during drives around town. EOT was high (220-240's). ECT around 195-200
- reservoir continued to sizzle and leak and fluctuated in fill level enough to make me crazy. Tested coolant using a tester from AutoZone to make sure I had good mix of coolant vs distilled water.
- Had to drive home 2 hours so left early in the AM to avoid afternoon Florida heat. EOT climbed to 250 so I pulled off and let it cool down before continuing. Kept speed at 60-65 the rest of the way which kept temp around 245.
- Next two days took two short drives (2 miles each). Fluctuations in coolant continued. Some mornings when cold coolant level showed above full. Other mornings the indicator had no coolant but looking down into tank there was still some coolant. Of course I added/drained as I felt appropriate. Re-tested to confirm correct concentration.
So that brings me to this... I hope I didn't hurt my truck! Yesterday I drove the truck to the gas station to fill up prior to taking it to a shop (it was very low on fuel). The gas station is only 2 miles from the house if that. The truck was running for maybe 20 minutes which from my experience doesn't get it that hot with respect to the oil temps. Got home, parked off the side of the road and checked under the hood as I have become accustom to. The radiator cap had coolant around it again and the level was not even visible. Radiator hoses were very hard... I removed the cap to relieve any gases that were in there and mowed my lawn. About an hour or so later I went to move it back in front of my house. Turned the key, waited a few seconds, she cranks a few times, goes to start but then instantly makes a noise and stops. I would describe the noise as maybe that sound you hear when trying to start a car that's already running... Or maybe it's just the sound of a diesel engine coming to a screeching halt? Tried to start it again and the same thing happened...cranks a few times, goes to start but then quick screech and off.
What could this be? This is the first time the truck has refused to start up. It has been sounding fine, running fine as far as sight and sound goes (no smoke, no knocking, etc) but obviously it does have something going on with the coolant level (maybe an air pocket) and also has the issue with the oil cooler.
I'm currently at a loss and don't know where to go from here. I'm probably just going to have it towed to a local shop but thought I'd see if anyone on here has run into something like this.
Also in case anyone on here is local to the Sarasota, FL area, I'm considering two shops. White's Diesel in Nokomis, FL and also Holder's Diesel in Sarasota/Bradenton. If you know either of these please respond with your experiences.
Thank you all!
