So I recently bought my 06 f350 and the truck was running great no problems like a true champ. 2 months pass by and my truck gives me an overheating message I check the degas bottle and it was empty so I added some more and I was golden 2 weeks later I get the message again and degas bottle was empty again. One week later I come to find out my fan clutch wasn't working properly so I replace it and I thought I had fixed my over heating problem but I thought wrong. Now while the truck hasn't overheated cause I'm always watching the degas bottle I lose all the coolant in the degas bottle over night or within 2 days. I can't find any drip marks on the drive way or find any coolant at all. Today I was trying to find it and I had the truck running and when I gently squeezed the upper hose coolant came out from where it's suppose to be clamped thight. Than I check the bottom hose and the hose is as hard as a rock. My truck is headstuded and egr deleted. It doesn't burn the coolant out the exhaust and my oil has not one single drop or coolant in it I need to find this leak and I need help I been searching up and down the forums but can't find anything please help I'm scared to drive the truck long distance. Thank you
Check the degas bottle for any cracks and then follow all your lines for possible holes. That is where I would start. Ive had two trucks now and both had the degas bottle crack somewhere. Just a though.
I've looked for leaks and don't see any stains around the degas area. I can't see any signs of coolant leaking into the engine with white smoke. My upper engine valley and EGR are dry. I have checked seen water leak on the ground, but it is clear and the only time I see it drip it's from the air conditioner, nothing the color of the ford gold coolant.
My next steps are to take the snake camera by the water pump to check for leaks at the water pump where the coolant runs in the engine and then along the degas bottle to the radiator and also along the heater core. I will pay particular attention to the underneath of the degas bottle. After that, I may pull the EGR valve to check for leaks. After that, I have a spare STANT cap I may drill to rig up with my air compressor to put 16 PSI in the system to see if I can hear a leak. If that doesn't work, I'll only take it on short trips and eventually the leak will show itself.
I noticed the higher temps during a three hour each way road trip I had higher than normal oil temps and higher than normal Coolant temps. I added a quart of distilled water and coolant temps and oil temps normalized. I added an additional quart yesterday, and it was low today.
The coolant had been steady for 10k miles after changed, and it's on the last trip I had to add some.
Guys thank you so much for your replies I will take off my degas bottle today and look for any cracks today when I get out of work I will see what I can find and post why progress
Believe my leak is coming from the block heater inserts into the engine between the steel ring and wire insulation.
I got under my truck today after adding an additional gallon of distilled water and found the starter had coolant leaked over it. I thought it would be the block plug which I've got the Fumoto valves attached to, but those were fine. Appeared to be coming from the Block heater. It's dry above the block heater, so it's not leaking from there.
Edit: Picture of the Fumoto valve is meant to show it's not leaking from there.
