In order to hold off on taking the dash apart or paying to have the heater core replaced, I’m going to bypass it for a while. I have seen conflicting information on the inlet and outlet hoses. Are they both 5/8” or is one 3/4”? Anyone done this on the 3.8L?
thanks

Question.. is it Leaking? If NO.. check out the video and it will show what size the hoses are too. :

yes, the heater core is leaking. The video is a 2012 3.6L. Still trying to confirm both hoses in the 2011 are 5/8”. Trying not to disconnect and measure it and make a mess before going to the parts store.

Here is the MOPAR 3.8L PN: 55056590AD HOSE, Heater Supply And Return Chrysler It is for both the hoses as a unit. My source does not have more details.

Both hoses/pipes are 5/8" or 16mm. When my heater core was leaking, i cut the pipes from my new and old heatercore, removed the glove compartment en all screws from passenger dash, pulled this back, cut the aluminium rail behind the glove compartment and cut the tubes from the old core, put some hoses and clamps on the remaining tubes, eyeballed the lengt of tubes on the old and new core, after removal, cut the pipes of the new core, installed it and connected the hoses and clamps. Still working great, and JEEP is getting warm again during winter.
