DEF Leak

[Lee Iacocca]

2022 2500 Longhorn Limited, just drove to the beach. 450 miles, took 5 gallons of DEF to get here. Noticed puddles when I stopped for diesel, leave engine going to keep grandchild cool in truck.Sorry for bad pics and possibly doubles. On my phone…..3,500 miles on her.

It's corrosive. Make sure it's cleaned up well. Maybe see about some rust preventative.

If you chip away at that iceberg and rinse the rest away it should be fairly obvious where the leak is coming from when you start the truck. It might be a quicker fix than leaving it at the dealer. Sure it should be their warranty job but what’s your time worth?

I would think you should take it to the dealer, just for documentation of the problem. If DEF is as corrosive as they say, who knows what may be affected in the future.

I'm with everyone else when it comes to dealer visits, I only go when it's for important recall issues, that are straight-forward to complete. I've even paid out-of-pocket and did the labor myself for some issues, rather then let the dealers do the work. Thankfully, that's been rare.

Warm/hot water is your best bet to remove the dried DEF, it will dissolve almost instantly

Checked underneath and she is very clean. Did happen to find a 3 foot screwdriver across two frame members that rode 500 miles…..nevermind the feet, they need lotion.
