well i had just said about a day or two ago that i had my 6.4 problem free, wrong . Got home today from work and forgot something in truck as i walked up to my truck i saw a couple of drops of liquid on the ground. As i did a better inspection i notice that it was from passenger side bottom of radiator, sdhflkslj! I called my dealer and asked if i could come in and get this checked out. After they inspected they said YES its your radiator . But after they went to check in there inventory i was relieved to find out that they had 2 in stock. Will be going in the morning and they said they sould have it done by in the afternoon as they are not too busy and they have a diesel tech available. Who else has had this problem and was it fixed the right way?

 

Make sure it is a certified rad that has the newer numbers or you will be back!
some folks out here have had 3 or 4 radiators

 

can you explain this some more?

 

Ya a bunch of radiators are junk and FMC did not know how many, the dealers put new junk radiators back in the trucks

A few hundred miles you where back for another (Made in Mexico) radiator! keep on
going to mexico Ford

Good thing they had one for you! Hopefully it will be a quick fix.
BTW - Nice Truck!!

 

Is leaking the only evidence of a bad radiator??? So far, mine shows no evidence of leaking. My F-550 was built the week of January 8. So it is almost a year old....I am assuming this was a bad batch of radiators that made it in the earlier production....
