    had coolant leak to aux heater. tracked it down to a leaky y connection directly behind the coil pack. Dealer wanted $190 for a replacement assy. Told me it can't be repaired. What I did was remove the plastic Y. and install a T fitting. On one end it goes to motor. other end I put one heater hose. I then used a small piece of heater hose to attach a 90 degree elbow to the open part of the T. This I connected to the other heater hose. Total cost. $27 including antifreeze and clamps. I bought a foot of heater hose but only used about half of it. No leaks and looks like it belongs there since my hoses aren't twisted at any weird angles. Total materials list. 1 T, 1 Elbow. 6 inches heater hose, 6 clamps and a gallon of antifreeze. No need to remove hoses from metal tubes at firewall either. Total repair time about 15 min.

    rear heat and return line v-shape connector under the hood against the fire wall, had developed a leak as the v-connector (made out of a nylon type material) cracked. I replaced it once already, and it now had developed another leak in the same location, so I am attempting to replace it yet again.

    heater core 'Y' connector leaking from seam in main piece. Smelled hot antifreeze but could find no leak at first. Finally tracked it down with car running watching the anti freeze spew out of the little pinhole!
    Dealers will not/cannot sell just the Y, comes as a unit with hoses/tubing etc. Installed about $350.00 Just replaced the Y with brass T and 24" of 5/8 heater hose and 3 regular hose clamps. About $19.00.
