Antifreeze Spray - 2006 w/ 89K miles - Hose Replacement?

It's currently July in Atlanta and have noticed, over the last week or two, that I smell antifreeze coming from my 2006 Commander 4.7 after driving it.

As of this writing, the car has 89,000 miles and is approximately 6 years old.

I was able to take a look at it today -- I took a video in the spirit of both gaining insight and sharing this with other owners who may be encountering the same problem.

URL to Video -- http://youtu.be/8XOuMBI5Hy8

I noticed some moisture around where the upper radiator hose meets the engine block. It also looks like the spray pattern in concentrated in that area as well -- I do not see any sort of residue elsewhere in the engine, with the exception of some at the lip of the overflow tank.

I'm thinking it may just need a new upper radiator hose, but took the video to help diagnose.

Also, when reviewing the owners manual -- it's recommended that you replace the coolant at 6 years or 102,000 so, based on the age of my car, I am due for that.

As far as next steps, I will replace the upper and lower radiator hoses (and, of course, the antifreeze). I will do some research as well, but if anyone can share what other coolant hoses that they have replaced around this time -- that would be appreciated.

It looks like the coolant has been changed with the incorrect type. The Commander requires HOAT coolant and is only available through your dealership or you can buy Zerex G-05 at Napa. OE coolant is pink in color while the Zerex coolant is more of a light yellow tone.

Regarding the splatter, it could possibly come from the water pump. There are some members on this forum with the 3.7L and 4.7L engines that had a leaky water pump gasket.

If I am not mistaken, those with a failing water pump gasket really never had that kind of spray.

Good luck.

I have the 2006 4.7 Commander too with 87,XXX miles on it. Guess what? I just noticed the SAME EXACT ISSUE!!!!

Went out to walk the dog this morning, noticed two small wet spots under the passenger side on the concrete (about the size of a pancake). Couldnt tell what they were at first glance, stuck my head under the vehicle and notices drippage in one spot. Looked kind of orange-ish... Popped the hood and orange splatter everywhere just like in your video. Nothing left in the coolant reservoir at all.

I just purchased this Jeep a little over a month ago and the reservoir was full at that time.

Anyways, I went to the dealership and got the proper mopar coolant and filled it back up. Drove around a little bit and so far no leakage. Just waiting to see if I can identify the problem myself before I do anything else.

Im no mechanic, but Im assuming its a hose, maybe the water pump... Not really sure.

If you figure it out or anyone else knows what the problem is, PLEASE! Fill me in. I would greatly appreciate it. Thanks in advance.

Thank you for the feedback. I bought the car at 75K, so didn't think that the incorrect coolant may have been put in there at one point -- but, of course, that is a reasonable assumption.

Good point about the water pump as well. From what I can tell, it looks like that upper radiator hose is weeping -- so have bought a replacement hose and (correct) coolant. I'll let you know how I fare -- and will keep my eye on the waterpump as well.

Thank you for sharing. I suppose the good thing about mass production (combined with the internet) is that we all have the exact same cars, so the exact same problems are likely to occur .....

In my case, I just noticed the smell of antifreeze and -- as I referenced in the video -- just saw that that it was being sprayed all over the top of the engine. I haven't lost a lot of coolant, though, so I am gathering it's a leak of some sort. I am replacing the upper radiator hose -- but will keep an eye on it still. My car now has 89K on it, so wouldn't be a bad idea to go ahead and replace the water pump anyway.

I just topped of my coolant last night in prep for tomorrows off road adventure with a brand new jug right from the dealer and its definitely not orange. More of a pinkish color. And it was the same color as the coolant that was already in the over flow tank. I just flushed the system in May with the exact same coolant from the dealer and its the same coolant all the new jeeps use.
