The flush-n-fill kits make short work of cleaning the old coolant and stuff
out and only cost a few dollars.

And as someone else mentioned use only Zerex Green or Zerex G-05 and
distilled water. The proper coolant is available at PepBoys and NAPA.

What these guys said. You only really need to remove the block drain, if
the cooling system is known to be full of sludge. On a vehicle this young,
I wouldn't expect that unless it had been overheated and refilled with raw
tap water several times.

Hi Dennis:

I couldn't find the drain plug either. I looked on my '02 and '06 Wrangler.
It seems to be buried behind all kinds of "stuff."

Here is what I did:

Thanks to all for your response.
Sounds like installing the flushing tee is the way to go. I had a rough time
finding the Zerex G-05 antifreeze. First I went to Carquest and they never
heard of it ,so then I went to Napa and they never heard of it, went to
Advance Auto and they don't carry it, and these are all vendors who are
supposed to have it. Don't have a Pep Boys in town
so my last chance was Auto Zone. They had it hidden away in a far corner of
the store away from all the rest of the antifreeze?????????

Thanks again,
Dennis B
