You should pick up a manual on your make & model, i.e. haynes books, it
might not be as "good" as shop manual, but youll at least get a feel for
where things are on your auto, then you wont have to wait on a usenet reply
for trivial questions. Have fun, Make sure you use a phosphate and borate
free coolant, =)

on the back of the block about oil filter level to the drivers side of
the filter, about 1-1/4 inches across with a 17 or 19 mm hex head.

19, IIRC. was able to get it off the first time 3 yrs ago. couldnt do it
again this time. ended up draining, refilling, ran the car...drained, then
refilled again. 50/50 orange prestone and distilled. radiator core still
looked brand new. wasted bout 3 qts worth of the stuff from the drain and
refill, but i know the mix is right and fresh. the temp gauge is even down
about 2 notches from center now.

the bolt is a major pain in the a.s to take off, even with the oil filter
below it off.

Yeah, good luck. I have the Honda maintenance manual for my 99 accord ex
auto and the information and graphic they provided for the coolant drain was
wrong. It wasn't located where the graphic showed it to be. I did find a
bolt in the approx vicinity that did not look like the one in the graphic
and started taking it out, but something didn't seem right as it was very
difficult to remove even after I had it most of the way out. Since I wasn't
at all sure what was going to come out once I removed the bolt, I eventually
tightened it back up and used the flush and fill method.

I have a '98 CRV and I've found it easier to remove the bolt from above. The
first time I did it by crawling under the vehicle and I had a little bit of
trouble aligning the fine threads on the bolt and threading it into the block.
The second time I decided to try to remove it from above and it was much
easier. The bolt is easily accessable from above.

Don't forget to put some teflon sealant on the threads before you reinstall
it.
