8k Miles, coolant leak, and Now a replacement engine

[dew34]

Thanks,

Do you know if there is a better # than 800-392-3673?

I had more contact info at one time but can't find it now, did a factory rep come look at your truck ? The dealer might be able to give you more on who to contact , as its going to be corporate ford that makes the decision on extended warranty . I will keep searching my emails for the contact info . ford , did you try 800 565 3673 thats customer relations

It's more than a puff of vapor, it's a puddle of coolant on the ground under the front diff. It's at the dealer again now; hopefully they figure it out today. I could see it running down the motor mount from below the truck, so I'm hoping it's just a bad turbo line. They topped it off Monday and added dye and told me to drive it for a couple weeks. I drove it 2 miles Tuesday night and then parked it. Wednesday morning it had a small puddle of coolant under it.

Oh...Nevermind then.

Update: mine was a failed water pump.

Update:

Took 6 weeks but I finally got the truck back. Engine was pulled, and the head was replaced.

Ford offered an extended warranty, which I accepted.

I was intermittently smelling coolant after shutting the truck off, and took it into the dealer this week.

They were having trouble diagnosing it, and finally figured out that it was leaking coolant at the back of the motor, and dripping on the exhaust which is why no puddle was to be found.

Now, 3 days later they've brought in a factory tech and have determined that there is a casting /machining issue with the passenger side head and at a minimum it will need to be replaced, or swap the entire motor.

I'm obviously not thrilled about a dealership tech getting that deep into the engine with only 8k miles. This now apparently lies with an FSE (field service engineer) to determine the next course of action, and they expect to have the truck for a couple weeks.

Has anyone experience similar? Is there any recompense to push for an extended warranty, etc?

This is the first new vehicle I've ever bought, out of the 15+ that i've owned. What a bummer.

Sh--, I hope i don't have that problem. My Ranger Raptor has recently started smelling of hot/burning coolant when I shut it down. Hope I don't have sane issue.

Good deal glad they offered it with out a bunch of BS !!! So it was a pin hole in the casting ?

I've had similar issue since new, intermittently smelling burning coolant. Reservoir is at the min mark but never bothered to look when I bought it to see if it was filled to that point new.

Haven't been able to find the source, if any so far, but if I do, I'll report back what I find. Just got mine pro cal tuned at about 6k miles, but issue has existed since I bought it with only 50 miles on it.

Been poking around but haven't found anything obvious yet. If I can track it down, I'll report back. Thinking it may also be a turbo coolant line or at the back dropping onto the exhaust since I does not see any accumulation anywhere

BTW, this seems to be a somewhat common issue with the 2.7L NANO's in the Bronco's, I would imagine some B-Raptors have seen that as well as I'm sure the 2.7L and 3.0L use many of the same fittings. Also, a common issue on the F-150 3.5L EB's.

My guess, quality control issues with Ford's suppliers for the fittings. Lowest bidder! I'm fairly convinced now the low coolant reservoir is due to a slow leak, not my other theory that it was filled improperly from the factory.

I wonder if any of the 2.7L XLT's have had this issue?
