Just did a drain and fill of the radiator.. what a mess.. and like they say coolant tastes sweet, YUK!

Anyway, just draining the radiator takes about 1.25 gallons and the total capacity is around 2.75 gallons so obviously ove half must be left in the engine block.

I did try to remove the engine block plugs but all I had was the 12-pt 14mm so I ended up stripping it before giving up. By the way, with a couple of ratchet extension (I used a 6" and a 2") along with one of those dual axis swivel extesions you can get at the left bank plug pretty easily... make sure you have a flashlight for your sanity.

Thise plugs are a pain to get out!!! I was able to get a socket on them, but I could not get them out (WUSS??!!) I think an air ratchet would've helped cuz they were on there pretty good...Anyways, since I was unable to remove plugs, I just drained radiator and replaced the coolant in the radiator...I assume I didn't get the proper mix (I went 50-50).
