Coolant question

So I have never done this before but want to learn/ know how to do it, thought this would be a good place to seek advice. I have a 1998 Jeep Wrangler SE with a 2.5L. Yesterday I looked at my coolant and it looks brown. To me, that's not good. I want to change/ drain it. If anyone could let me know what I have to do to drain it and replace the coolant that would be great. Any special tools? how much coolant to get to fill the system after drain. I'm not totally mechanically inclined but I'm not an expert as well. I just like to learn about the vehicle I drive everyday.

Thanks!

It depends on how far you want to go and how much blockage has already occurred.
Your heater core And radiator are probably plugging up with the sludge in your cooling system.

A simple backflush kit from an auto parts store could fix your issue.
Or take it in and have a shop flush and fill it.

Do you still have good, hot heat?
Is your engine running hotter than normal?

Engine is running fine. Heat is good as well. Just the color looks bad and I don't know when the last time it was flushed.

A simple flush and fill would probably be sufficient for now. Personally, I'd still have the shop do it.
