coolant drain plugs on block

[surferfletch]

Where are they? 3.2L V6. I'm in the middle of the job and wondering how to drain all the coolant from the block. Help!

You're a lifesaver! Thanks!

Still looking...

Found it. Wonder why the Haynes says there are two plugs, one on either side of the block. I went out and bought a 1/2" breaker bar, 3" exension, and 27mm socket for $40 at Lowe's. Sucks to find out the 27 mm socket doesn't fit! Going back out...

Tomorrow...

Closest I can get to the 28mm socket is with an 1 1/8"socket (=28.575mm). Sears only has 29mm, Lowe's 30mm. Let's see if I round it off...

Any suggestions? How much water stays in the block after the flush if I don't get the coolant drain plug off?

No clue.

I flush my yearly. I just buy that quart bottle of flush stuff for 2 bucks and follow the directions.

Done. I used the Zerex coolant flush. I finally got the plug broken and backed out. 28mm would have been right, but the 1-1/8" didn't strip the head. Capacity is 9.7 qts., but I put in about 8 qts. (50% distilled water, 50% coolant).

Worried that I started leaking from somewhere near the tranny, but the drip stream seems to have stopped. Heat works. Wish I knew what the temp is, but I lost the temp guage about a year ago.

Thanks for the help!

Anyone know of any write-ups on a coolant flush procedure???

1. Remove the radiator cap.
2. Loosen the drain cog/wingthing on the lower drivers side of the radiator.
3. Catch the fluid.
4. Dump in a bottle of flush stuff, then top of with your garden hose (or DI water).
5. Follow the directions on the flush bottle, which is something like run the truck for 15 minutes, turn off drain and do it 2 more times.
6. Pull the reserve tank and empty that. The last time I did this I cleaned out the inside with a rag and soapy water since there was some black gunky build up in it.
7. reinstall tank.
8. Top off radiator with a 50-50 mix (mix with DI water). Add to reserve tank. Drive it a couple days then check your reserve tank and test your antifreeze concentration.


I do mine yearly. If you take it to a shop they will hook it up to a machine to flush out the entire system, but I think my yearly flush will work fine too.

What about the coolant mix left in the block?

[amigo-2k]

well, I aways thought that if you did the fill up with water, and run the truck for 10-15 minutes it mixs a bit, so when you do that 3-4times you will get most of it out of the block, and then you just add a little extra antifreeze to your mix to make up for it. On the downside you will have a bit of garden hose water in the block. My last truck I did this every 3yrs, and the radiator lasted a 165k (sold it 4 years ago at 181k, and I saw it a couple months ago still tooling around) and I never had a problem with the heator core.

I'm too anal. I couldn't sleep knowing that there was partially treated wastewater (from the hose) and some amount of flush in the block. Could have done without the headache of chasing down tools, though.

But think you're ready for next time!
