Re: drain plugs on 06 Tahoe merc 5.0
Thanks for all the help guys! I should have taken pix, but I`m not that computer literate. Sorry. I think I got it figured out. I found one blue plastic drain on each side of the block and 2 others, one on each side of the engine. After I had run the engine for a while on muffs to change the oil, I drained all of the blue plugs which held quite a bit of water. Just to be safe after that, I pulled all the hoses off the thermostat manifold and poured 3 gallons of rv antifreeze in the hoses with the drain plugs reinserted. I believe the thermostat was still open from the running, cause I poured 2 quarts into the manifold, and I could here it going down, somewhere. This 3 gallons may have been overkill, but I have a warm fuzzy that all that fluid found it`s way to every nook and cranny.
