Ok, I'm lost here. Most recommendations I've seen say we can go 30,000 miles between PTU fluid changes. Are people changing fluid at 30,000 or 10,000 in the OEM PTU? Thanks

Check your owners manual. Mine says SAE 80w-90 for RDU and SAE 75w-140 for PTU

That tube you used is a little bigger than what I had on-hand. Next time I'll give it a try. I used AMSOL in my last PTU change and I've got Motorcraft ready for the next. I was late on the RDU and wanted to get it done because there are mentions of RDU failure/replacements here and on youtube. The fluid I took out was really bad. Another thing I noticed is the rust and pitting on the exhaust pipe from my cat on back to the muffler. Isn't this supposed to be stainless? Looks like it will fail soon and I'll need a new pipe and muffler.

Not sure what diameter of silicone tube you're using, the only tube I could get to fit was 1/4 inch. The RDU is packed tight with gears and a big one right behind the fill plug opening. It took me three stores to find SAE 80w-90. Finally settled on Lucas SAE 80w-90 heavy duty gear oil. Thanks

Ok, that's what I was looking for. Hoping the fluid change will prevent a RDU failure. Thanks

Is there a drain plug on the 2018 RDU? My 2018 PTU has a drain plug. Did they put a drain plug on the RDU in 2018? Videos on the subject show a pump out by hand from the fill plug and not getting all the old fluid out. Thanks

Is this fake?

No, I didn't upgrade the battery just went with the recommended one from the Interstate website for my 2018 Edge 3.5L. Thanks. Just wanted to be sure.

I put in the recommended battery from Interstate. Besides resetting the BMS is there any other changes I need to make?

Perfect. So the new tire is on the same rear axle as a tire that's just been riding around not used for much braking or acceleration. It's just like a new tire. Those tires will be moved to the front in the rotation. Thanks

2018 Edge Titanium 3.5L AWD

Pretty sure my rear axle doesn't disengage at cruise speeds. That feature was added to 2020 and later AWD models. Starting tomorrow I'll be rotating my tires twice a year with each oil change.

Ok, after every oil change. Thanks

Yea, saw that. But when? After how many miles?

Wow 2/32 -3/32 isn't much. This is my first AWD car. Drove 100 miles today, no issues no messages drove great. I'm not seeing in the owners manual where it says how many miles between tire rotations. When I bought the tires they recommended about 6000 miles. I'm way past that and should've been watching it. This means my front tires are worn as they do most of the stopping. When I get them rotated this would put the new tire up front. So I think I'm ok with a tire rotation. Fingers crossed. Thanks.

I also got this recall for my 2018 Edge with 3.5L V6. The car just passed emissions test fine, I have no lights or issues and am reluctant to take it in.

My rear driver side tire picked up a screw and started leaking. Screw was to close too sidewall for repair and had to be replaced. All four tires were 80,000 mile tires with only 11,000 miles on them. Tires haven't been rotated. Tire shop replaced the tire with exact same tire brand and tread under road hazard warranty. Asked if it was ok as this being an AWD, they said it was because there wasn't a lot of miles on them. Is this ok? Should I get the tires rotated? That would put the new tire up on the front passenger side. Thanks

Obtained digital battery tester a month ago. The attached image is what showed 28 days ago. Followed the "recharge" suggestion from the meter and then retested everything seemed fine. Drove it out to the field, about 45 minute drive from my house without issue. Visited with friends for 6 hours. Edge wouldn't start, click click click. Used my jump starter, started up and drove home. During the drive home auto dimming message came on and dimmed my instrument lights. Could hardly read the speedometer. Next morning voltage on the battery was 12.5 and tester now showed "BAD" not "REPLACE" but "BAD", really! well there was no way I wasn't going to replace it! Did so and reset BMS.

Hi, was the problem found and fixed? I have a 2018 similar Edge. thanks

Is there a terminal I can clip a 12 volt power source on and maintain the vehicle's memory? Can I use the cigar lighter socket? If I attach a 12 volt power source to the cigar lighter socket while disconnecting the battery will that maintain the vehicle's memory? Thanks

My 2018 Titanium came with a nice paper copy in the glove box. No idea when they stopped doing it.

Yeah, that's what I figured. Wasn't sure if it prevented power from going in or just turned off for power coming out. I'll have to use the aligator clips and go to the battery and ground under the hood. Thanks

Purchased a Solar powered battery maintainer to maintain my battery while my 2018 Edge is parked in the parking lot. It came with a cigarette lighter plug adaptor or aligator clips to directly connect to the battery. I will ground the charger to the vehicle not the negitive battery post. Would like to use the cigarette lighter plug for the convenience, but will it work? Or is this a bad idea? Thanks.

Thanks for the replies. It was way to hard to use my fingers, so I tried pliers. That's when it looked like it may break off! Now have the radiator petcock socket tool for next attempt. I have four, one gallon jugs of motorcraft premix yelloe coolant. That's what I'll be filling with. Compressed air sounds like a good idea, I'll try that to get more of the old coolant out.
