My sis recently acquired a 98 monte 3.1 liter. she said she didn't have any heat. looking under the hood i discovered that there was a hose just dangling. upon further inspection it seems someone has attempted to bypass the heater core for whatever reason. My question is, does anyone have a good picture to show where the hoses SHOULD be attached? I've read several good threads regarding heater core and no heat on here, but couldn't find anything regarding placement of hoses.

 

well if theh where bypassing the heater core the should be 2 metal pipes sticking out of the firewall where the heater core would be. thats where the would hook up. i have a sneaky suspicion that

 

heater core craped out and someone didnt want to bother replacing it so you will probably be doing one

 

Yup I kinda figured that's exactly why the bypassed it. My problem however, is figuring out where the hoses are actually supposed to go. There is still one hose on the bottom spout of the heater core but is not connecting to anything. The top spout is bare. Where does the hose that's connected to bottom spout and nothing else go? And what hose hooks to the top spout of the core?

 

the bypass...? i assuming the botom w hose still on it is the outlet top is the inlet so is the bypass 2 peices of hose or just one?

 

Chances are the heater was leaking water if they decided to disconnect the thing rather than just not use it.

 

my advice is start to yant out the heater core first when you have the old one out and the new one in. then worrie about the heater core hoses. because the heater core will take all of your time then figuring out the inlet and outlet hoses. because when you have the new one in you will notice the bypass.

 

Should be 2 hose connections on the firewall, and then 2 hose connections on the engine- back on the passenger side. Should just plug straight engine to firewall. Pretty straightforward.

 

Any trick for getting the lower hose clamp off the fire wall?
