    I plan to drain/replace my coolant soon. I do not want to do a coolant "flush".

    My question is where, specifically, are the "engine block drain plugs"? Does anyone have good photos? I have the Haynes and the photo (p. 1-24) is so tight and doesn't provide an adequate description of location (for me). I need, at least, a reference to the locations of these two plugs (e.g., front side of oil filter...or something like that).

    Thank you for any help on this.

    Will have two plugs at /around oil filter ..will be the bigger one. Takes a 17mm hex head. Now the passenger side is smaller above the starter.

    Thanks Mr. Dipstick. I found similar info on other sites after a bit of googling. Most people recommend a flush (with the t connector). I haven't done a flush or drain (in my brief tenure), but since I already bought the 50/50 Dexcool, I am going to attempt the drain this weekend. I plan to only drain the driver's side block plug as the passenger side is apparrently blocked by the starter. Interestingly, my radiator drain hose is missing. I plan to use full goggles for this job. Any further hints/things to watch out for appreciated very much.Weekend Wrench06 Sierra 4wd 5.3L 4 door 135,000 miles
