There are none.
The engine block coolant drain plug on a 350 Chevy Tahoe is above the oil pan, mid engine on driver's side
One on each side of the block about center of the block just above where the oil pan touches the block. Plug is 9/16
Only one drain plug on a 350 that's the oil drain. on forward part of lowest part of pan. The radiator will have one depending on model on where it is. New answer- There are 2 water drain plugs on all V8 blocks, And you can find them 1 on each side of block, They our in the center of the block just above were the oil pan bolts on the block. They will be real short and takes a 1/2 inch socket to remove.
just above the oil pan rail about halfway down the length of the block on both sides.
YES. If you look at the passenger side of the engine block just in front of the starter you will see a small plug that is screwed into the side of the block. That is a coolant drain plug so you can get all the coolant out of the block. Remove it and screw the knock sensor in it's place.
180.
In place of the coolant drain plug on either side of the block.
The heads themselves have NO freeze plugs in them. But the block/engine has 8 freeze plugs in it.
they are casting plugs you will find them on each side of the engine block below the heads
It has 8 freeze plugs. 2 in the back of the block, 2 on each side of the block, and 2 in the front 1 on each side of the timing cover.
It will be screewed into the drivers side head between the first 2 spark plugs.
9/16 and I have seen some 1/2 inch.
