#16 of 21 03 Sedona rear coolant lines (rear heater lines) by vince17 Mar 06, 2008 (6:08 pm)
I own a 03 Sedona and upon preparing for a road trip I dropped down my rear spare tire to check inflation.After doing so I inspected the rear coolant line that connects to the rear heater fan and found it rotted.Rust was forming as well as over resonator. Now my Sedona is pristine and garaged (about only 20500 miles at that time).The NewYork winters havent been bad this past few years so road salt is not a big issue.Kia said I would have to pay a tech to inspect line but since it wasnt leaking yet I dont think they would warranty a replacement .I purchased the rear coolant line as the dealer was selling the replacement part regularly(114 bucks) Got a can of under coating and sprayed the new line like it was a hornets nest .Tech bulliten says you gotta drop the resonator ,(wasnt that over kill?) Anyhow I seperated the lines from the three quarter inch rubber hose connections(corked them lines to keep antifreeze from completely leakinking out of engine block) unbolt hard line clamps (2 of em)Disassemble rear splash gaurd , twist off connections from rear heater and wow allmost done.Now im soaked with anti freeze,bolt up new lines TAKE OUT CORKS FROM MIDDLE RUBBER CONNECTIONS ,open radiator cap so antifreeze gravity bleeds to rear line put radiator cap back clamp rear connection.and bingo rear line installed.Anyhow sent digi foto of rear line with invoice for part along with a dealer work order for some work the week before(showing odometer milage).Got a case number and Kias sending me a refund for part cost.I like this van I use to go on vacation,I thank this site cause I never would have checked that line.The others lines seem fine(oh and the spare tire was LOW.

Replying to: byyall (Jul 19, 2007 1:41 pm) I had the same problem as #9. It turned out that the "RR Heat" button was pressed by one of the kids. They thought it had to be pressed for the rear vents to work with AC. They were WRONG. Replies to this message: byyall (Nov 11, 2008 8:50 pm)

Replying to: autobuyer4 (Nov 10, 2008 6:59 am) Unfortunately this was not the problem with us. The dealer in Florence, SC was so accomodating about all of the problems we have experienced. Something is still wrong with the left side of the AC with it still blowing hot air. They also had a notice (they actually had another term for this) about the passenger back sliding door. They did adjustments and we hoped it was right; however, it is still not closing right and sometimes will open enough for the light showing that a door is ajar. SOOO, we will take it back when we can (it is 80 miles from us).   The van itself is great. I don't like the steering to be so tight, it makes my hands tired. However, I still love the van. The gas mileage is great, 22.5 per gallon on a trip and still good around town. Carolyn

The ac in my van has a leak put a vacuum pump on and pulled 29hg turned off the pump after closing the valve. I let it sit for two hours still 29hg vacuum I replaced the high and low valves vacuumed and refilled. Check system with electronic leak detector and bubble solution no leaks found. The next day got in the van no ac just hot air, hooked up gauges low refrigerant. I put a can of UV dye in and refilled ran unit for two hours checked the whole system with a UV lamp still can't find a leak can any one help?

Replying to: hothanddd (Jul 22, 2009 3:24 pm) I had a similar problem where the pressure showed good while recharged and running, then if the van sat for a day or two and didn't use AC, the unit would blow hot air. I eventually found the high pressure hose that is located between the radiator and the motor had a slight amount of oil on it (has some foil wrap on it). I didn't see it until I removed the plastic shroud off the underside of the engine area, crawled under it and looked up. After changing the hose and the drier assy, recharged and worked well.  It's important to install a new drier and o-rings to the fittings anytime you open and replace any part of the system. Also add a little AC compressor oil when you do this. Replies to this message: byyall (Sep 07, 2009 8:45 pm)

Replying to: darkwater27 (Sep 07, 2009 8:27 am) How many miles did you have on the van at the time? Mine has done this since I bought it new in June 2006. Our Columbia, SC dealer has just gotten a new service manager and I PRAY he will get the place in shape. It is a shame to love the van but it has problems they should have been able to repair. I sometimes feel they are waiting for it to go out of warranty!!
