where is it leaking from? there are a couple common places either from the drivers side of the radiator on the end tank where the tank is crimped. There is a TSB on it and if your under warranty get your radiator replaced. Also the top of the degas bottle. The min max lines were incorrectly printed on bottle so maybe try and keep your coolant and the min line and see how that works out for you. Another spot is the upper radiator hose on the earlier builds would crack another TSB I believe but will be covered under warranty and will be updated to the newest one that has 2 o-rings as well.

If those aren't it you might have blown head gaskets or might need to replace the front cover.

interesting most of the issues I've hear with the hoses is the upper hose where the t-stat is. But go out for a drive then park open up the hood and check all on the driver side and just trace the cooling system.

You say your leaking but are you seeing a puddle under your truck any where or you just losing coolant. Because if you have a puddle then thats easier to trace but if your just losing coolant that could be more of a pain. either blown headgaskets or egr coolers but worst case would be you have cracked heads.

Hopefully your under warranty

I highly doubt you have any head problems....


It it not uncommon for the hose connections to start leaking, bottom and top. Ford has released updated hoses with double the o rings to fix this problem. This is most likely the culprit.

I have also had the recirc line off the degas bottle leak, took it to the dealer and they found the leak at 14#'s, had to put a new clamp on it and now no issues with it leaking.

I just discovered a leak on my 09 on lower radiator hose at the clamp. I had an 08 that leaked at both upper and lower hose. Very common on these trucks.

Yes it is very common. Ford has come out with some updated hoses that have double the o rings I believe. I have them on my truck now and haven't had any more issues.

Martin1,
I have a 08 F350 with 69K miles and have sprung a leak on a hose connection. My question for you is was your leak on a connection and was the new connection covered under warranty?
