Tools Needed:
-3/8 ratchet
-12 inches of extensions 3/8 drive.
-3/8 drive 5/16 allen socket to remove passenger side plug.
-1/2 in ratchet
-1/2 in extensions (12) inches worth.
-1/2 in drive 17 mm allen socket to remove drivers side plug.
-Hammer
Parts Needed:
-Liquid Teflon Pipe Sealant
-2 Gallons Dexcool Antifreeze
-2 Gallons of Distilled Water
Purpose:
This is to completely drain the block of all the Dexcool antifreeze.
How - To:
Step 1
On the pass side there is a plug that lies flat just above the starter between the starter and the block. You'll need the 5/16 allen socket to remove.
You may have to add the extensions together to get to this plug, when you do leave the ratchet off for now and "lightly" tap on the extension when the allen socket is inserted in the plug to jar it loose.
You should not have to remove the starter for this but if your having a hard time getting the plug out or in, just set it aside.
Step 2
On the drivers side towards the front there is a 17 mm plug that is on a slant that goes with the slant of the block.
Same goes here, just tap on the extensions with the allen socket inserted to loosen and then remove.
Step 3
Now you are ready to install the plugs. I put some teflon pipe sealant on the threads and the flat sealing suface of the plugs and threaded them in and snug em up.
Step 4
Step 1, 2, and 3 were done after you drained the radiator and antifreeze overflow bottle.
Step 5
Refill system with 50/50 mix of Dexcool antifreeze---not the green stuff/bad for aluminum!
Thats it, top it off and fill the overflow bottle to the full cold mark and close all tops.
Good Luck
And Make Sure You Do This While Motor Is COOL.
