Anyways, guess no one has that.
On a side note.
I was trying to figure out which hose to plug the prestone bakflush kit into. Anyone done that.

Never done the flush kit, but what do you mean by diagram? Like an actual picture, or just how the coolant flows?
If you just want an idea of how the coolant flows, the water pump sucks the coolant out of the radiator (thru the lower radiator hose). The pump pushes the coolant thru the motor (thru the block, intake manifold, then cylinder heads). Then if the thermostat's open, the coolant goes back to the radiator thru the upper radiator hose.
During all this, the heater hoses get coolant, too. The feed line for the heater core is the heater hose/fitting that comes out of the intake manifold (the pipe fitting right below the thermostat). The coolant goes thru the heater core and goes back into the engine via the heater hose that goes to the water pump.
Not sure where you'd put the backflush hose. Reverse flow would be upper rad hose -> engine -> water pump -> lower rad hose, but how do you get the pump to spin backwards? Never thought about it. And the thermostat would have to be open, right?
And for the hell of it, that's why the cooling system on the "new" LT1 f-body motors was impressive; it was a reverse flow design. Instead of traditional flow (block -> intake -> heads), the LT1 sends coolant to the heads first, which allows for a more controlled combustion chamber temperature. If you think about the coolant flow on our motors, by the time the coolant gets to our heads, it's already hot, and can't cool the heads down as much as if the heads got the coolant first.

That's what I was trying to figure out.
Which hose I was supposed to plug into.

Here, searched and found a message for ya about it. There's a ton more, but this one caught my eye first: https://www.thirdgen.org/techbb2/sho...threadid=28173

It's the V6 hoses thta are confusing me.
I did it on the monte, no probs...
Came thing with Rick, he's gotthe v8, and the hose is easy to find on there....
Some times I really hate my V6.
