Neon yellow fluid on my driveway

[merkman]

2003 Dodge Ram Quad Cab 4X4 1500 Magnum V8 150,000 miles

I notice neon yellow fluid under it (on the snow) from time to time.

Looks like it is 2 spots around the center of the truck (between drivers and passengers seat) on the ground.

Any ideas what may be leaking.. or is it just marking its territory?

What color is your coolant? If its DexCool, it might be it. I know Dex is orange, but diluted and mixed with snow, it might be yellow.

I agree with Zamboni. Coolant.

Once you go through the colors of all of the other fluids

the only one left is the coolant.

Keep an eye on it. A few drops isn't bad.

My guess would be coolant too, but I'm not sure what color it is in Dodges. I know the Dexcool in our Chevy's is definitely orange when it leaks out whether it's diluted or not.

Neon yellow? That's radiated urine. I think your truck is fine, but you might want to keep an eye out for little green men though!!!

I believe Dodge started using yellow coolant in 2001. Any amount of leakage indicates a growing problem. I'd check it out sooner than later.

Yup, If your seeing it on the ground its a big enough problem to deserve a little investigation to find its source.

That is what I was worried about.

[merkman]

I will have it checked out.

Hey everyone, I just noticed this exact same fluid under my 94 Ford Ranger. I'm out in MD and we just got 30 inches of snow over night. I was shoveling the drive and moved the truck out when I saw it. At first I thought it was coming from the rear dif, cause it was right between the rear wheels, but on further inspection (crawling under the passenger side of the thing) I noticed the neon yellow [PoorWordUsage] dripping off the exhaust pipe and muffler. No idea what the heck is causing it, and I hope it's not fluid dripping out of another line and onto the exhaust system. Merkman, have you been able to get under your truck to see anything?

Hope this helps,

Charlie

P.S. I'm from So. St. Paul -- used to this kind of snow of course, but DC is completely shut down! All of the schools are closed (they close if there is a threat of snow) and most buisnesses are closed too. They are ill equiped to move this stuff.

Neon yellow? Could be R-134 from your A/C system. The normal color is a neon green color, but if leak detecting dye has been added it becomes a yellow/orange color.

This what I was thinking!

Welcome to HSO ChuckSeders!! I am not sure what would be back by the middle of the truck that would have this color in it.

No it didn't taste like pee... it had more of an artificial taste.... just kidding.
