just picked up a 2019 Ram 1500 with the 5.7 Hemi. When I first got it home I found the radiator cap was loose and antifreeze had spilled all over engine. Truck has 17000 miles on it. Dealer refilled the antifreeze and sent me on my way. Every time I drive it I get an antifreeze smell under the hood. Does not seem to lose fluid and dealer pressure tested system with no leaks but still has a strong smell. Will be hauling a travel trailer soon and don"t need any problems. Any suggestions?

Welcome , it takes a bit of time and miles for the antifreeze to burn off from where it spilled / sprayed .

ive had the same problem but minus the spill, dealer says all is well, have 27000 on my 11 month old 1500. Hope if a problem presents itself it does it while under warranty.

My truck is 15 months old with 30,000 miles. I tow my 24ft boat with it in the summer. I've had the smell since day 1. Coolant level never changes. I found that the smell seems to come from the overflow tank. The yellow cap fits loosely on the tank, and smell comes from there on my truck.

I suspect that is my culprit, it seems the looser it gets the more smell. probably will get a heavier gasket on it.

Came here about to post the same.. mine has a burning antifreeze smell coming from under the hood on the drivers side as well. All temps and levels look good here as well. I’ll head to dealer once all this nonsense blows over. Please post results if u figure it out.

Interesting. My 2019 has the same smell. But is from the passenger side. The smell is strongest around the metal radiator cap. I am wondering if it is a bad gasket in the cap. This was a known issue in older Honda's. Considering very few parts in a modern RAM come from the US, they might use the same vendor as Honda for all we know.
As others have stated, I have not noticed an appreciable loss of fluid level in the overflow tank. So, I am guessing it is vapors escaping from a weak cap gasket. I plan to order a replacement and see if the smell goes away. I have 26,780 miles on mine.
I will post an update if a new cap rectifies the situation.

I had time to take mine into the dealership and they told me my Borla muffler was causing it. Yes, I’m serious. I just took my keys off the counter and walked out. I don’t need anyone that stupid working on my truck.

I replaced my radiator cap this morning. Yes, before I started it up for the first time today
Anyway, it has been 10 hours now since I replaced the radiator cap, truck has been driven 4 times today. No antifreeze smell.
I will report back in a few days to claim victory if the smell does not return.
By the way, the cap was $16. Worth every penny.

I had the same smell for a while now. at 35,000 miles I took it to the dealer to have it looked at. They replaced the radiator cap and pressure tested it and it held pressure for hours. i Noticed the smell again 200 miles later.....

Mine has had the smell since day 1.
Dealership tells me there's nothing wrong and that it's "normal" although this is the first vehicle I've had that smells like coolant after I've driven it. The overflow lid thing was very loose and wouldn't stay 'snapped' in place so I had it taped down and the dealership did replace that.
Since there's no loss of coolant or visible leaks they tell me there's nothing else they can do.
I will probably try the radiator cap replacement to see if that helps.
