This is a big problem on most mini vans with rear heaters. One of the work
arounds would be to run standard heater hose (probably 5/8″) from the tee
(that you capped off) all the way to the rear core or at least to the most
solid piece of pipe left in the rear section, using HD clamps and retain
the rear heat.
Just a tip, replace the hose under the hood where you’ve capped off the tee
or put in a 90 degree elbow to eliminate an additional point of failure at
the cap.
…continued… Then install the long section from the bottom by snaking it
past the exhaust. It will rub a little bit. After mounting it, go back up
top to reconnect the tee fittings.
Gmurray658 I saw people saying that too but it’s not technically true. I
did it on regular jack stands. You just need enough room to lay underneath
and reach your arm up past the exhaust to unscrew the mounting bolts and
reinstall. The secret is to disconnect the heater line Tee fitting before
installing the new part. The two tee fittings with connections to the
engine block and front heater core should be installed from the top. Take
out the air intake box and hose to throttle body first.
Did you replace the hose(s) by placing the van on a lift or from
ramps/jacks? I was told it’s impossible without placing it on a lift? How
did you do it?
They fixed the coolant line issue with the 2006 and up Kia Sedonas. I have
a 2005 Kia Sedona, and had this happen at around 60,000 miles. Not fun!
Steve Miller, this IS a 2006 Kia Sedona, so I don’t think the issue is
fixed. Maybe they tried or said they did, but…
