2001 Wrangler Coolant Drain?
 

Got a 2001 Wrangler Sport with the 4.0 engine.
I want to change the anti-freeze and wonder if someone could help me with a
some questions.
Does this engine have drain plugs in the block and if so where are they
located?
If no drain plugs then how does the old coolant get drained?
Should the thermostat be removed before flushing?
Better yet could someone please explain the proper procedure for flushing
the coolant system on this vehicle?
I want to do it right, that's why I came here.
Thanks for any help.

4 liter block drain plug location:

You can also remove the lower radiator hose

Use coolant CONCENTRATE and DISTILLED water to make your 50/50

The only coolant, that I am sure, meets the old DC 'Green" spec is
Valvoline's Zerex Original Green or, if you prefer, DC recommends you
upgrade to the new G-05 spec. The only supplier, that I am aware of, in the
aftermarket is Valvoline's Zerex G-05 coolant.

It is available at PepBoys and NAPA.

FWIW: I find a flush-n-fill kit very useful and well worth the few dollars
they cost. You cannot do a comparable job wit the old drain/refill
procedure.

No, you can leave the t-stat in.

Be aware that the heater core will still hold a fair amount of water so
you should add half the system's volume of pure antifreeze and then top
it up with distilled water.
