Draining coolant from the block
Draining coolant from the block
'99 5.4L, So, I want to flush out the old coolant and put some clean stuff in there. I saw the online writeup about draining the coolant from the block and it seems like coolant will end up going everywhere and making a mess if I just take the drain plug off. Is there a recommended way of doing this without necessitating removing a bunch of crap?

I figured that part out. I'm talking about draining the actual block itself. According to the Haynes book, there's a drain plug on each side of the block too.
hmm, I'll have to look at my manuals. Your not refering to the freeze plugs are you.
When I drained the my 99 4.6 block, I put a pail underneath so the coolant would not go all over the driveway.
Damn, I would do it for $50 - Simple, takes no time to speak of once you know what your doin.
I did a write up on that, - if you find it, let me know would yuh.
There's a inset (female) allen bolt (T55 I believe)/drivers side. If you have a drain plug on the passenger side , consider yourself lucky because I never seen one on that side and I've looked on a few different trucks.
You'll need impact action to get her out or you'll most likely strip it. Tape it before you install.
Good Luck

I wondered why I did not get nearly enough coolant out that I thought I would get when I did a first change about two years ago.
I decided last year that I would just drain what I can from the radiator valve and just refill that once a year. Its very simple and quick to do (other than waiting for it to drain but I usually tinker with other things while Im waiting). After several years, its almost like getting a complete change and always keeps fresh coolant in there.

You lucked out having two plugs, mine absolutely does not! I went as far as wire wheeling the entire passenger side of the block. No Plug
Same deal on a 99 I work on once in awhile, except for the wire wheeling part (*** that, not doing that again).. I haven't check the 01 yet. What's the deal, why just one on some?
Ball valves a good idea - that's where it gets messy
-Coolant hits to many obstacles on the way down before making it to the bucket. Yea that would be nifty, connect a piece of tube to the valve right ?You have a lock on that valve? That would suck if you hit a chuck hole hard and she turned on

-What about debris/foreign matter flying into the valve, turning it ? -or possibly taking it out completely

Hope your not paranoid now .
