Dodge Grand Caravan Problem Report
Dodge Grand Caravan Auxillary Heater Hose Connections May Develop Coolant Leaks
The auxiliary heater hose connections (that are routed to the rear heater under the vehicle) can develop coolant leaks.
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. - Visitor
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. - Visitor
Top of Y fitting split open and was spraying coolant every time gas pedal was pressed. Was discovered by horrible odor and smoke/steam eminiating from under hood while driving. Was dropped at dealer as emergency repair & repaired under extendand warranty - total repair would have been $186. Car would have been undrivable though. - Visitor
metal hose is rusted and leaking all coolant - Visitor
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. - Visitor

Same issue with Y connector. Took van in for other issues that are covered by the lifetime warranty on the drivetrain and mechanic at the Dodge dealership found the Y connector problem that was making the heater hose swell. - Visitor

antifreeze leaks from heater hose onto engine causing smoke and stinky smell. keep having to add antifreeze until found out by looking while heater is on and saw a stream of liquid (antifreeze) squirting onto engine area. looking for a solution and anticipate cost to fix problem - Visitor
When the van runs a while the coolant leaks out and steam and that smell comes from the hood. When I stop for a while it stops. - Visitor
tube underneath the van behind the front wheel just in front of rubber hose just before tubing goes up to the engine has a pinhole leak. Cut tubing back and cut tubing off metal bracket. Installed new longer rubber hose and zip tied hose to bracket - Visitor
2010 Grand Caravan. Approx 63,000 miles. The same Y connection near the manifold has sprung a leak. The seam now has a hole. To repair it, as many others have done, I spliced the two hoses feeding out of the Y connectors, replaced the Y connector with Oreilly Auto's part 84757. Purchased a 5/8 inch heater hose to connect from the back of the engine to the Y connector. It's all fixed for now, but I may go to Lowe's and get the metal T part number APXT34 as shown in https://www.youtube.com/watch?v=DBNyZQD9LD8 - Visitor
