Hi HMAC300. Excuse me for butting in, ... Again. This was a real common problem with a pretty easy fix. The rear heater hoses have plastic quick-connect fittings at the rear heater core. Those fittings have a rubber o-ring that shrinks and leaks in cold weather. Manufacturers always insist that warranty repairs be made with their parts. The engineers came up with a pair of superseded part numbers for this repair. Those had TWO o-rings in each fitting that shrunk and leaked in cold weather!

When the van is out of warranty, the less-expensive and permanent fix is to cut off the metal crimped bands on the front of the hoses right behind the cross member, cut those hoses off, then install two new rubber hoses from bulk stock. I can't remember the diameter or if both hoses were the same. The pipes in front and the nipples for the heater core are barbed, so just slide the new hoses on and use regular hose clamps. If you leave the original hoses in place, you can use tie straps to hold the new hoses to those old ones.

If you're made of money, you can install a pair of 3"-long hoses to the heater core, then a pair of 90 degree elbows from the hardware store's plumbing department. Attach the new hoses to those elbows. For the rest of us, just watch that there are no kinks in the new hoses. They need to make some rather tight bends right under the heater core.

It can take weeks of driving to get the rear heater core to burp the air out and start the coolant circulating. What I did instead was to build pressure in the cooling system, either with a pressure tester or by running the engine, use a hose pinch-off pliers to pinch one of the new hoses, then loosen the clamp on that hose at the heater core. Thanks to the pressure, the coolant was forced to flow into the heater core, and through to the loosened clamp. Any air trapped in there yet will work its way out in short order.

Antifreeze is pouring out as fast as I pour it in! It is coming from the passenger side, about center, higher up but only visible from below. Looks like a hose or right where a hose connects to something? Little to dark to see clearly. I know enough just to be dangerous but cant afford to take it in somewhere. Any ideas? Or do you know where I can find free pics of the cooling system so I can figure it out? Thanks!

If you have rear heat, the lines that run to the rear are common for rotting out and leaking. It is a very involved job to replace the line set as they come as a set.

The other possibility is the water pump. It could have a bad seal and leaking from the weep hole.

Get a shop to verify it for you and give you a bid.

I looked all around for any better pictures for you but all are generic and vague.

Like I said, it is involved as the lines are long and twisty and require a lot of removal to get them out and the new ones in.

Wish I could be more help but this is it. I will defer to my partners to see if there is any better pictures.

Maybe you can get someone to help you familiar with cars. Also, go to autozone and let them show you a picture of the lines so you can see what I mean

Its prolly the water pump. It is sorta a job for someone that is not truely familiar with it. I would rather go to napa than autozone I only have good luck there with oil. If it does turn out to be water pump spend the lil extra cash at napa or you will be doing it again soon. (Sorry autozone)

You need the leak verified, no matter what. We all are guessing here based on experience.

Yes your right. Get a mirror make sure everything is dry and start the van and look where it is coming from. Be careful of the belt.

Is it safe and workable to splice and tape multiple (10+) wires in the wiring harness that are corroded or apart due to an antifreeze leak? Also, could this problem ( faulty electrical wires in wiring harness) be correctly located and diagnosed with a computer check? Mechanic replaced the transmission first and then found the electrical problem. Thank you.

Everyone gets fooled at one time or another, expensive mistake! The codes would have refered to circuits being high or low voltage. Connectors are the first check!

I have a 98 Chrysler Town And Country with 154000 miles, I noticed it leaking a couple days ago but after that one time didnt see it leak no more till today it overheated and when I Checked the water there was none in there so I added water but noticed it was leaking out and making a pissssing noise and looked as though steam or something was comming out too. But it looked like it was coming from under the van it looked to be about under where the front seats are but under the car so I dont know what needs to be fixed?

Does it ahve rear heat? If so they it might be the rear heater lines that run to the right rear of the car for the heater core. Those lines are famous for rusting out.

I took it to the shop today to see what was wrong and that is exactly what it was the rear heater lines. My friend said they could clip and crimp the lines if I dont need the rear heat is that true? Is that safe? Thank you.
