99 accord block coolant drain plug

Can anyone tell me where this is? I thought it was below the oil
filter on the back of the block, but I can't find it. Thanks.

Which engine?

If you are talking about the 4 cylinder engine, its usually above the oil
filter on the back. Unless you have a lift and enough leverage to get a
long breaker bar extension on it, its not going to come out.

 

I had problems with this also. I even have the Helms manual and the plug
shown in the book did not match reality. I found a plug/bolt in the general
vicinity, but it definitely did not match the diagram. I started taking it
out (it was hard to loosen), but it didn't feel right. It was very stiff
even after I had it most of the way out. Since I didn't know what behind
it, I ended up tightening it back up and just flushing with a hose by
draining at the radiator, filling it up, running until hot, and repeating a
couple times. If I were doing this again, I would flush with distilled
water instead of the hose. It would only take a 2-3 gallons and I would not
have introduced calcium laden water into the system.

I remember being very frustrated that the Helms manual was wrong. What
would have taken less than an hour if I could have drained the engine block
instead took me over two hours.

Don't worry about it. I spent 30 minutes looking for it on my 99EX 4cyl and
could not find it. I actually loosened the only bolt in the area and a very
small amount of fluid (oil?) leaked out and I quickly put it back. I work
near a Honda dealer and asked at the service desk. The service tech smiled
and said to just drain the radiator.

Assuming you have the 4-cyl engine, the drain bolt is directly below
the oil filter. The first thing you come to below the filter. If you
remove it (the manual says to take it out after draining the
radiator), you need to apply liquid gasket to the threads, use a new
washer, and torque to 61 ft lbs. Ref: Shop manual page 10-9

I think I found it. Thanks for all the messages! It was slightly
above and to the left of the oil filter. It's behind a lip and can't
be seen from directly below. I couldn't loosen it however, even with
a breaker bar and hammer.

 

I too, took a long time looking for the plug on my 99 LX 4 cyl. And it
was on there pretty damn tight, but I did get it loose. I was
disappointed when I too, had a very small amount of fluid dribble out.
It puzzled me too, it didn't look like pure coolant, it was sort of
oily. I wonder what the deal is.

Next time I change the coolant, I have no plans to loosen that bolt
again.

p.s. After I tightened it, w/ no sealer etc. I have had no leaks from
it.

 

When I finally got the plug loose, I was only using a ratchet with a
pretty decent length handle, but it didn't come loose easily. (Extra
*!#& words helped)
I had my car up on drive-up ramps.

No, the others are correct - it's to the left and slightly above the oil
filter. It's the only thing around with a 19mm A/F hex bolt head on it.
The plug below the oil filter, with a hex socket hole, is the oil pressure
relief valve plug.
