Back story: Bought the Jeep 3 years ago and within a week of owning it I replaced the radiator, t-stat, and hoses due to a clog (damn you Previous owner!!!) even with numerous flushes I've lived with no heat since then.
Now my water pump has started to leak... So I am trying to do as much at once as I have the Jeep down for maintenance so here is my list.
New belt
Heater core
Water pump
Water pump inlet tube (mine is rusted out)
A/C delete ???? looking into this a little more..
Evap core ???? thinking about it
I am ordering all the parts online due to lack of auto stores where I'm located. so if you guys know of any good sites and brands I should go with let me know!
Also if you guys have any tips or tricks for me please let me know!!

Are you sure your heater core is bad? You may want to do some research on how to flush it out before trying to replace it. I haven't personally replaced one but a friend of mine replaced his, followed by the windshield he punched...

I have done a lot of research and flushed forward, backwards, I even tried to run cleaner through it with no luck. I am about 98.3% positive that its the heater core. I just never had the guts/time to pull the dash so I suffered over the winters. Now I have some time and I don't feel like going through another coolant change without getting the heater core replaced... and maybe a windshield

Are the flushes not flowing thru the core? If they are, then hot coolant should also be flowing thru. Both heater hoses at the firewall should be very hot. If they are both hot, the heater box flapper door may not be moving to the correct position to allow air to flow thru the hot heater core out to the cab.
