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.
