There is antifreeze leaking from the rear of my 2005 kia sedona. I I am not sure what it is leaking from but there is 2 hoses under there! Why would there be antifreeze in the rear of the van?

    I had the same problem. Our local mechanic had to replace rusted out pipes to the back and then insulate what wasn't yet ruined. I no longer have the leak, but now due to the insulation, it's very loud in the van. My van is less than 5 years old!

After speaking with a dealership the warranty only covers the rear lines till 60000 miles, so if you have a 2005 Sedona that is nearing 60000 miles I sugest you check and see if the lines are rusting.

Many vans have rear heater cores for added passenger comfort, so this is not unusual, it is very possiable either the hoses or there connections to the rear eater core are leaking or the heater core itself is leaking.

I have a 2005 Kia Sedona 3.5 that I fill it with water and I put 50/50 antifreeze in the reservoir . 2 days later nothing , and I never see a leak , never ??


Any white smoke from exhaust? Any white foam in the oil? Water doesn't just disappear. It must be going somewhere. Bad radiator cap letting coolant escape while driving? Any overheating?

2002 kia sedona is loosing coolant.....within 2 days after filling the reservoir to FULL, it went a little more than halfway down to low . No leaking on ground. Sometimes smell coolant inside van after...


The heater core is leaking into the heaterbox under the dash. Which is why you smell antifreeze/coolant inside. After a while (if left go too long) you'll notice antifreeze on the floor/carpet and possibly running out from under the vehicle as it flows out of the drain for the air conditioner (the heaterbox has a drain in it to let out the moisture produced by the a/c)

2005 kia sedona 76,000 overheats the engine


My 2005 KIA Sedona started overheating in Winter 2009/2010 and was loosing antifreeze. No leaks from the heater hoses or radiator hose. No pressure in the radiator either.

I had found a site where folks were discussing the same things and someone brought up the rear heater. Apparently KIA has run steel hoses running under the chasis to the rear of the van and these rot.

I looked under the rear at the wheel well and located the lines and they were wet with antifreeze. I traced the lines to the firewall and found where the lines were connected to the coolant system and bypassed the rear heater lines.

I then filled up the radiator and overflow tank with antifreeze and started the van. I rocked the van to get air to move out of the lines and kept adding antifreeze until it was full. then used the overflow tank to top it off.

Hope this helps.

Looking for a heater core pipe (front)


If your carpet is getting wet under the dash and around , then you probably need a new heater core. If it is a simple leak that requires you to replace the hose ot clamp, then the heater core is leaking from the outside into the engine compartment instead of the inside of the car.
