Question about 1998 Dodge Caravan

I am trying to change the return heater hose on my 1998 Dodge Caravan 3.8 ltr engine. The top clamp is easy to get to. How do I get to the bottom clamp that seems to be surrounded by hoses and metal parts?

What I do is: get a flexible carburetor screwdriver then in the 1/4" socket end I insert a socket screwdriver tip etc. these wire cable type screwdrivers can be found at autopart stores they also work great with power screwdrivers

Where are heater core hoses in 2003 dodge grand caravan?


You will find them under the hood.
Do you know what the heater core is? About the size of a hard-back book, it is a small radiator with engine coolant passing through it. It is located inside the heater case under the dash.
There are two hoses, an inlet line and a return line. Both same size, about 1 inch in diameter. Both hoses come from the engine and go up to the firewall behind the engine. Both hoses connect to the heater core right at the firewall, so there are hose clamps on the end of the hoses.
You can remove and replace the heater hoses right there under the hood, pretty easy too. But if you need to replace the heater core, that comes out from under the dash. Often there is a lot of work to get to the core, as there is a loot in the way.

If the original y-fitting is ok. Just get yourself a piece of heater hose. The auto store may have heater hose on a roll, You may need to tell them the ID and how long, they just cut a length for you and you use hose clamp. I'm not sure what you bought/an assembly? Maybe you can take it back and just get a piece of hose? Of course, I can't see anything from here?
I did find this picture.

Trying to locate the heater inlet hose for a 1998 dodge caravan


I had a 98 caravan for 3 years, but I don't have it anymore. Going off memory but I recall both the inlet and outlet hoses are near the center of the firewall directly below the windshield. If it is a 3.3. or 3.8 the Intake Plenum is kind of in the way, but it is not difficult to remove.
If you are planning on removing the heater core, good luck. I have heard the whole dash must be removed.

I have a 1998 dodge caravan with 117k orig miles. it was a 1 owner van and i noticed a small smell of antifreeze after i get out of the van when it is hot/warm. nothing is leaking on the bottom emd like...


well it is 11 years old now so it could well be a rotten rubber water hose or a gasket showing its age,, try putting in some red food coloring in the rad that should stain where the water is leaking out of?
antifreeze will stink even from a pin hole,,,in the heater rad?
