Heater core is leaking inside jeepy, so I bypass with extra hose and blow air through core till no more fluid comes out, but is there a right way to delete it? How hard is it to fix?

 

Seeing how you live in a warm climate, you can bypass your heater core (At the valve) till it is fixed. Just be like driving an old VW bug. No heat, No Def. Keep a couple of rags and a scraper in the glove box. (in case of steam and frost)

 

You deleted it the right way by the sound of it.

If you've never done a heater core before, plan on an entire day to do it yourself. Maybe 2 days if you really take your time

 

Replacing the core is kind of PITA, if you bypassed it then it is pretty much deleted.
if you need the heater to work, then prepare for a day or two of work, as the removal and installation of a new one are kind of difficult due to the awkward position you need to work on, I'm in Costa Rica and we do not need the heater, so when it started to leak, we just bypass the hose and that's it!

 

I just replaced mine - and it is a massive pain in the *** that requires removing the entire dash (or at the very least getting it loose enough to move aside). I actually had to replace the AC evaporator core, and decided to do the heater core too. On retrospect, that was a great idea, because I would not want to do that twice. I would recommend swapping out for a new Evaporator core also if you go that route.
A big thing to warn you about with doing it yourself is that you have to evacuate and recharge the AC system, because removing the heater core requires taking out the whole HVAC cabin box. There is a good write up for it somewhere on this forum. It's basically the same as the Evaporator core replacement instructions.
All in all, the job took me about 8-10 hours of total work spread out over two days. If you think you can get by without heat, I would say avoid doing it, because that job is a big one.
