Alright guys so I flushed my radiator and heater core about a week ago and filled it back up with good antifreeze. Sadly I still don't consistently have good heat. Both of the heater core hoses are hot when at running temperature and when I try to run the heat the belts start squeaking like a stuck hog. I'm running out of ideas here somebody help me lol
Is the jeep getting up to normal operating temp (210)? Did you flush and then burp the system with the heater on high?

No, I don't lick fish.
Pop's Jeep sat too long and now the caliper is stuck. What a smell. At least I was able to get it home.
If I replace the front calipers, do I have to bleed RR, RL, FR, FL or can I just bleed the fronts? I don't want to risk ringing off the rear bleeder valves and increasing my job time.

If you keep enough fluid in the resevoir, you might be able to get away with it... but why chance it? Not to mention, if it's been sitting that long, moisture could have collected in the lines and fluid and cause them to not work efficiently anyway. Best to just do a full drain, fill, and bleed of the whole system. It's not hard.
I paid 5 bucks for this at harbor freight http://www.harborfreight.com/automot...kit-37201.html and while primitive, it makes one-person-bleeding much much easier.
You're on an open system. As long as there's the proper amount of fluid in your reservoir tank and your radiator cap is holding proper pressure, your radiator should take care of evacuating the air on its own.

Right! The temps may act funny until all the air gets out (if there's any). Happened to me after my last flush. Took like 3 days until it was good. Thought maybe that would affect the heat output.

It certainly could, depending on where the air bubbles are sitting. You may not be getting much (if any) hot coolant to your heater core.
I just went through this a few weeks ago when I replaced the rear heater lines on a minivan. Squeezing the upper radiator hose to disturb the flow may help evacuate the air faster

Lol... Man, it's sad. I should be able to answer this because I just did this. But I can't remember. I'll try to remember to crawl under the jeep in the morning and look. I think I eliminated it though when I upgrade the cables.

Man I greatly appreciate your help! When I was looking to tackle the alternator cable, I saw that damn thing and thought "what in the blazing hell??". I almost thought it was some kind of ground... for an alternator!!!

I don't think they are. The only thing the computer asks at the auto parts store I work at is if they are 9" or 10". Most likely 9". Way to tell is if the drums are finned they are 10". Also how the brake lines go into the wheel cylinders. If they go straight in, left and right are the same, then it is 9". If they go in at an angle, left and right are different, then they are 10".
