I think I have some sort of blockage somewhere in my cooling system and wanna flush it out. There's supposed to be two drain plugs on the block itself, one on each side, but the picture in the FSM isn't really helping me to actually find them. Anybody got real some photos that can help me find them, or describe to me what they're near?

 

Check out the pictures in this thread , all the way to the bottom.

One plug is between the oil cooler and oil filter , the other one is almost in the same place on the other side.

Why does it looks like it's pointing up

 

your looking at the wrong one , its the circled one.

 

ooooh...that makes so much more sense I couldn't figure out for the life of me where the water passages were that low in the block... thanks a bunch

And just out of curiosity, what's the lower one for?

 

Are you talking about the oil dipstick hole??

 

That makes so much sense. Thanks

 

I was trying to find the coolant plugs as well. RMA's photo is gone, so I am posting another. Is the circled bolt the drain plug?

 

Doesn't that end up behind the motor mount? (There's a hole through the motor mount for the dipstick tube) Is it reasonably accessible with the motor in the truck?
