For any of you that have a small coolant leak like I had, when the truck sat and engine got cold. Ford put some O-rings in the radiator hoses, which mine were bad for some reason, that might be your issue. Like I stated it only leaked when the engine was cold, after I ran it the O-rings must have swollen back up and sealed off. The leak was on the driver front of the engine, I couldn't see a leak but it ran down the block onto my driveway, wasn't much but I knew it was there. On another note the dealer told me my "bed pan" was leaking oil which I knew something was leaking cause of the oil on my starter, that's gonna require an engine pull to fix so I am gonna wait till I get a bigger punch list. Sorry so long but hope it helps anyone else.

 

Wow...

The dreaded bedplate leak used to be a common problem with the 6.0s, this is the first I've heard of it on a 6.4L. Considering the bottom end is nearly identical it makes sense that the 6.4L would be susceptible to this as well.

 

Couple of bedplates but too wide spread.

I have just a tad coolant creep. Always have. Maybe an oz or two every 3-6 months. My OA's come back squeakie clean. No evidence either.

I think in my case I run it hard and I think some evaps overtime.

Bedplate will be a cab off procedure.

 

Old hoses had 1 o ring they now have 2

 

My upper radiator hose at the water pump connection started leaking at 42,000 miles. Ford denied the repair under warranty and quoted me $650 for new hose and coolant flush. I ordered two O-rings from Ford for $5, picked some gold coolant from NAPA and repaired in about 2 hours. The old O-Rings were visibly flattened into an oval shape which explains the leaking. New O-Rings are different color and appear to be made from different rubber compound as well.

 

I got 2 new hoses & flush, new coolant, $250.00

 

WOW!!! Guess I should thank my dealer, I had 44,000 miles....didn't question anything, my salesperson met me halfway to my house ( bout 1-1/2 hrs away to dealership) and gave me a loaner F-150 super crew for a week (cause they were so busy and couldn't get to my truck right away). I got one heck of a good dealership, cost me notta...
Yeah Senix, my service writer told me they would have to pull the engine. I'll get to that later when they're not so busy.

 

I might need to find a new dealer!

 

My upper hose was leaking at the engine connection.

First Dealer denied a warranty repair and quoted $750.00 to replace both hoses.

Second dealer replaced the O-Ring on the upper hose under warranty. No more leak.

Thanks to the original poster (peefrog) for mentioning the issue is with the O-ring and not the entire hose. You saved me $750.00.

 

How many O-rings are there?

 

The original hose had one at each end.

They have redesigned the radiator hose so that it now has two o-rings at each end. I still have the old style hose wand they replaced the one o-ring on mine.

 

hm.. $600 for my two hoses a few months back.. wonder if it was just the o-rings now..

What dealers did you go to?

 

Champion Ford (Gulf Freeway/Fugua) wanted to replace the hoses (both of them) and would not do it under warranty. Price $750.00

AC Collins Ford (BW 8 - Pasadena) replaced the o-rings under warranty. Actual Cost: $0.00

 

has anyone priced the replacement hoses without the labor? Why is this a $600-$750 job?
