Hello,
I believe you are referring to the heater hoses on the back side of the engine. There is 1 right under the intake manifold. and 1 on the back side. Most likely the heater control valve broke.The best place to get the hoses from is the dealer. They will have the direct fit molded hoses that you need.
Thanks Ryan K
Not sure I know what you are talking about. So I follow the pipe from the water pump along side the engine to the back side where the heater hose connects to the heater core pipe. From the heater core pipes there is another hose that goes down to the engine block under the intake manifold. The one hose has a heater control valve that has a vacuum line attached to it. The bushing that you are talking about where is it coming out of? Is it the heater hose it self or is it coming out of the fire wall?
Sounds like one of the water jacket plugs came off.Is it silver and about the size of a quarter or bigger? You can only get those from the dealer.They just pop in with a little help of a hammer.
