This van is equipped with rear air and heat. The hose tee simply diverts some of the hot antifreeze from the engine to the rear heater core for heating purposes. These tee's are often made of high temp plastics and have a tendency to crack. The part isn't expensive but the labor can be a bit high due to the placement and access. I figure this job should cost somewhere between $150 to $250 depending on who you take it to to be repaired. hope this helps your situation. Good luck.

Let the mechanic replace the hose T. It may be hard to spot the leak. What I would do is get a pressure tester and apply pressure to the system at the radiator cap (make sure its full of fluid) Then you should be able to easily identify where the leak is coming from. It will shoot out of the Tee most likely if thats where the crack is.

No heat on 02 kia sportage, a/c works great. I dont think the heater vore is bad because there is no antifreeze leaking anywhere. I changed thermostat and the radiator is full, still no heat


Follow the hoses to the heater core/firewall. When up to temp, both lines should hot, about the same temp. To hot to keep your hand on for to long. If one is a lot cooler, it's the heater core. After that I would check the controller or the blend door actuator.

I have white smoke/steam coming from my air vents and antifreeze leaking from a spout in my firewall. Any ideas/solutions?


Your heater core is leaking steamed antifreeze into the vents and possible out the firewall,where the heater hoses connect to it. Have that checked out.

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.

My van is leaking antifreeze from somewhere by the firewall of the van not the radiator. Its the metal hose that has a hole in it but i can't figure out the name of these metal (aluminum)hoses.


The metal hose by the firewall is either your heater core inlet pipe or outlet pipe. These inlet and outlet pipes will develop leaks for a varity of reasons. If this is the source of your leak, you may want to replace the entire heater core which is much easier than trying to fix the leak. The attached link will help you.

When heater is on smoke comes out of the vents


If it smells like antifreeze, your probably looking at a new heater core, just make sure you check hoses going into firewall from engine side to make sure it isn't a leak by end of hose, leaking down into that heater core area inside. If your coolant keeps going down, that's more than likely where it's going.Make sure you check coolant level .

Heater core leaks! temp in car interior fluctuates; HELP!


yup, its running to that point before it dripps off. you can bypass the heater core to stop the leaking, but you won't have heat. take the two heater core hoses ( two hoses connected at the fire wall on passenger side) and connect them together. you will need a fitting to connect them with.
