I wouldn't trust them for "all the fluid changes". I would ask for the service details from their work order to know exactly what they did. They may not consider differential normal service because it is lifetime for example. Could just be engine oil and check fluid levels.

It would not show up on Carfax. Ask the dealer for an oasis report of all service history. Then you'll know.

 

Will do, I’ll text him this morning.

Out of all the vehicles I’ve seen, I’ve only seen a few that had a 3.73 rear end.

We never buy used so the whole process makes me nervous.

 

I don't mean to agree, but I do. I see so many people ridiculously overload their trucks with travel trailers. I would look under the towing screen, see if the previous trailers are stored, and see how many miles. I also would like to see the oasis report, but ??? I have done all my maintenance, before it was due, keep records, but usually those are pitched by the clean up boys. Follow your gut, insist on being in drivers seat on a cold start, don't let them pull it it up front for you.

 

My dad has a 2014 XLT Crew Cab with the 5.0 and that has been a great truck for him. He used to pull a 21 Ft. boat with it before he had to sell the boat. I seldom tow with my 2.7 and that is just a single axle aluminum trailer with a Polaris Ranger UTV, or a lawn mower when I do. It is definitely capable of pulling twice what I pull though. The 3.5 with it's low end torque has a better reputation for towing than the 5.0 with its higher RPM's before reaching torque peak. The 3.5 is a very good motor except for the weak spot being the phasers and chains.

 

Do the chain issues apply to the 2018 model? I've read where that issue was primarily on the Gen 1 engines? I'm new to the EcoBoost so I'm trying to educate myself pretty quick.

Evidently the 2015 was sold in between me talking to the sales manager yesterday morning and him never calling me back, so as of now the 2018 3.5L is #1 until we find others of course. Ugh!

 

I'm not aware of any chain issues on the 2nd gens, I think it is just the phasers? The chain design was changed to help improve the chain durability?

 

2018's had a software update for the timing chains/phasers which I believe allowed the engine to turn over during a delayed start when cold to allow oil to be disbursed to the internal components quicker before startup. Ford had a bulletin for extended phaser coverage if I recall correctly. Problem not as bad as the earlier generation. The 2018 3.5 was also known for RTV sealant failure on the plastic oil pan for a few of the owners. Some owners had to have the oil pan replaced with a new one before solving the issue.

 

I just read about all of that again this morning, and saw mention of the RTV. I guess it's a chance you take but seems they would fix it all regardless of mileage.

You'll actually want to read Supplement #3 which is newer:

One more item worth confirming. I presume they did replace the phasers by now in that 2018. --> Check to see if the part number is one of the two listed in the TSB.

You probably want to jump on this quick if you decide... what are you thinking? Did the dealer provide you with the service history?
