22RE Coolant Drain - Where??

My toyota manual for my 91' 4Runner claims that there is a coolant drain cock on the engine (Page CO-5, step #3. According to the picture it looks like its on the drivers side but I can't find anything on my engine block that looks like a drain. In the picture it looks like a bolt. I can't imagine that this would be a misprint so do any of you know where the drain on the engine is? If it does exist how would you get to it? In between the frame rail and the block is the exhaust, very tight space.

Do you know if this block drain exists? I've always just drained the radiator but I figured if I can get the most out the better.

I didn't find a drain on my 91 when I had to pull the engine. And I caught most of the coolant when I drained the radiator. Maybe lost a pint or two.... Anyhow, we've got far too many cats, dogs and small kids in the neighborhood anyways to worry about loosing a few.
Heck, I've come home to find someone else parked in my driveway, which ticked me off considerably until I saw a driver come out of another house, and no one come out of mine.

Thanks guys, at least I know it's not me now. I could have sworn I know what a drain cock looks like. I'll just continue to do the radiator from now on.

there's a drain on the bottom of the radiator, two plug / prongs that stick out that you have to unscrew

not sure about the block, but you could always pull of hoses

There is a drain plug on the side of the engine block on 22RE`s, i just can`t remember what side of the engine its on right now, i know its towards the back of the block and its not a drain cock, its a screw in plug that looks more like a bolt.

On my '86 there is a drain cock waay down on the drivers side... it's about a 10 or 12 mm bolt in the side of the block; that drains the block out. It's probably hidden underneath the downpipe / exhaust manifold making it tough to see. If you crawl under or look at the right angle, it should be visible.

Hope this helps,
Yusuf

Right, it's on the driver's side toward the back. If you pull the plug, you may not get any liquid out until you go in the hole with a piece of stiff wire and clean out all the FIPG. Then you will get about 1/2 gallon.

Old thread, but I was looking for the drain plug on the engine block as well. I had noticed the bolt head but was unsure at the time if that the was the plug or not. Thanks for the pictures to confirm, desconhecido. It was a PITA to get at and a 17mm socket was needed as well as a wide catch pan.
