Radiator Hose Problems of Dodge Grand Caravan

The cooling system started a leak near the firewall where are the metal tubing connects 2 each y plastic connectors. It is one solid piece that wraps around the top of the engine and factory price is $185 no third party available. After inspecting the y connectors they are made of very very thin abs plastic. At 125000 miles had to replace it twice within 50000 miles the second time I used 2 each brass tee connectors with additional 5/8 heater hose and spliced it together for a better stronger connection. This has made the fourth high pressure leak I've had and 60,000 miles.

There was a smell of hot coolant anytime we were driving. I took it to the dealer and they said there was bad connection on the heater hose assembly and it would be $525 to fix. Upon investigation in the Dodge forums, this is an issue that is happening on a regular basis due to the heater hoses being directly above the exhaust collector and is causing the rubber to fail and thus causing coolant leaks. Best case is it smells when the coolant is leaking on the exhaust, worst case is people are getting stranded due to overheating. Dodge claims this is not covered under warranty.

There is a heater hose assembly leading from the top of the engine to the heater cores in the passenger compartment. A hose comes out of the engine and into a y-coupling, where it splits into two hoses. One hose leads into the firewall and the front heater core. The second goes under the vehicle to the back heater core. A coolant leak developed in the y-coupling, leaking coolant onto the exhaust. After leaking for some time, the check engine light came on to indicate low coolant. . Read more...
