Hot Weather: No leak...Cold Weather: leak!

My Truck: 2003, F250, 6.0

I have had an interesting problem for the past week. Here in town (jackson,MS) we have had some ridiculous cold weather 15-25 degrees!!

= Anywase, I had my truck in the shop recently for a coolant leak, and they said it was fine. So tuesday thru friday i did not drive my truck and the weather got sooo cold and i noticed a slow coolant leak. Then the leak got larger and eventually let out enough (a gallon?) that i could not see any in the resevoir, soo i got really scared and friday i went and got some of the gold coolant and put that in 50/50 and started her and let her warm up for a good 20 minutes. No leak after that, then i got back home around friday night and let it sit over night with the tmep around 60, still pretty chilly. and it didn't leak a drop, or through today. I'm confused. any ideas? Cracked seal possibly? it drips right down between front of tranny beside i think the downpipe.

there is a orange hose right below the turbo , it connects the egr cooler and oil cooler , that is probably what leaking , temperature can effect when and how they leak, if its dripping of the back side of the engine near the down tube thats your problem

Thank you so much. Can you give me instructions on how to access that??

if your truck is under 100k you should be able to get this covered under your engine warranty...

if not...you remove the turbo, drain tube, and pedestal....twist the hose so it will release (if you look at the horazontal edge where it connects to the oil cooler...it will be all round with two flat edges 90 degrees from each other...both flat edges need to be vertical)....and then VERY GENTLY bend the tube for the EGR cooler up till you can get the hose off and the new one on.....

well first off make sure you verify thats what is leaking b ut im pretty sure that your problem, there is an updated hose because of this problem, the new hose should be blue , if you pull the intercooler tube that connects to the turbo you can see it good , ther are two 27 torx bit screws that hold down the housing pull those two screws and use two pry bars to wiggle that housing and it will pop up, then pull on that housing and the hose will come with it , twist the ornage hose and pull it off , replace it with the blue new hose and reinstall ,refill the coolant ,make sure you dont have any leaks

might want to try my way marc, takes 10 minutes , no turbo removal required

thank you fellas so much. Since it is under warrenty, how long should a job like that take? I can't get to school/work/girlfriend without truck if you know what i mean. Is the way Marc said for the same hose, or a differnt typical leak spot?

[SCUFFY828]

same leak, just different way of doing it , but if its under warranty , i wouldnt care how its done, let them worry about it
