heater core

Looks like I have to replace my heater core. Any easy way to do this? Haven't checked it out fully, but looks like maybe some studs on the firewall hold it in? Any experience appreciated. Thx

I guess I jumped on the forum too quick. This turned out to be a no brainer so far. (Old core was trash). Waiting for the new core, then button it up. Looks like only about 1-1/2 hrs start to finish ....not counting scratching my head....thx

Do you have the AC stuff under dash?

No, thank God. That would've probably had me on social security before I got it out. I got the no frills model- about on the same level as a mail jeep. The only thing I forgot was to hook up the blower motor on the firewall side. Found out tonight when I drove it. A little contortioning to reach it, and it's all good. Still got the random wierd thing with the idle tho. Will deal with that tomorrow if I get time.

@wylie - My heater works very well, just need to make sure that the vacuum door is properly set and I have a faint smell of coolant. Hopefully, I can see what's going on through the glovebox space.

@Spidey---Mine worked great too, but I also had a faint smell of coolant...and it got a little stronger as time went on. Wasn't running out the drain, either. The core wasn't broke loose on the nipples, but was bad in the center of it. Wasn't really loosing fluid very noticably, but I'm sure in the summer it would defeat the point of a pressure cap and give me overheating issues. I never did figure out how to get the glovebox out . On mine, I don't think it would have helped to pull it for a look or access or anything. Like I said, mine was easy 'cause there aren't a lot of extras on it to get in the way. I just pulled the dash panel that covers the gauges, which took out the radio, undid the 4 bolts on the firewall and the fan motor wire, (after the battery tray was out- I'm lazy), yanked the drain, pulled the heater back and undid the control cables, and it popped right out.

Not really what I wanted to hear
Guess I'll have to do it at some time or another. Hopefully, what the FSM, Haynes and other forum sources state, it'll come out from underneath the AC stuff just the same as yours.
Yes, I'm lazy, too.
Really, tho, thanks for the input. I'll do it after it gets a bit more consistently warm.

Sorry it wasn't the news to brighten your day...but...things being what they are; if the weather is good and you make the time available so you aren't under the gun, and take your time, it likely won't be as bad as it could be. This seems to always be the case for myself. Good luck on it. This forum will be a lifesaver resource too. . If I can give any info that will actually help. let me know.

Wylie and Spidey, Thanks for this post. There was several things you both talked about that saved me a lot of work and concern. Did mine is about 2 hours but had to fight with bad carpet and old hoses. I cannot express the help I found here.

Glad to be any help at all. Wasn't too bad as long as you take your time, right? 2 hrs. ain't bad at all. (Nice to have a good heater where you're at).

Bruce, forgot to ask whether or not you have AC. I finally had the wet floorboard on the passenger side so I looped the heater hoses, basically taking the heater out of the cooling system. This way, I can take my time to remove then repair/replace.
