Water drip from engine compartment?

Noticed a small puddle of water accumulating under my parked JKU. Pools under the Jeep under the back middle of the engine compartment. I have not had the AC on, but it has seemed to be on warmer days. Can't tell where it is originating from, but the puddle ends up the size of maybe a softball.

Is this anything to worry about or are others having the same thing???

I know you haven't used the AC, but do you use the defroster? Do you have the automatic climate option? Just maybe, the AC compressor is running and you're not aware of it?

Just a thought....


Just another Billet Silver Metallic. It blends.

Water from car washes or rain enter the cowl grate which funnels water into a small tube that hangs just above the bell housing. The water drains onto the ground at approx. where engine and trans meet.

No climate control option, but I have had the fan on. No rain or car wash in the past few days, so I know it's not that. Hmm??

If you had the controls set to defog, the AC compressor will cycle on and off to help dry the air so it doesn't fog the windshield. Based on your description there is no other explanation.

From your description it sounds like the water is from the AC drain.

I don't know what year your jeep is but here's a picture of where the AC drain tube is located on the 2012 Wrangler which is just above the transmission. The photo is taken from the driver side looking back to the firewall.

I haven't looked underneath at my A/C drain tube, but it drips onto something hot, because every time I park, I hear "drip, sizzle, drip, sizzle, drip, sizzle." Kinda funny.
