Heater hose and tranny lines

[willyrocket]

90 Blazer with 350/700R4. Trying to finsh up rebuilt motor install. Its been out awhile and I need to figure out 2 things.

1. Replaced heater core, which line goes to the block and which one goes to radiator.

2. Transmission lines from tranny to radiator. Going to install tranny cooler and need to know which line is the return line. Is it the top or bottom on the radiator?

Cant wait to get er done and show her off!!!!!!!!!!!!!!

I am assuming this is one of those great things that is interchangable throughout all chevy's?

The heater hoses are 2 different diameters, so it's pretty difficult to hook them up wrong.

Just what I needed, just to confirm, top tranny line from radiator is the return line.

Thanks again and I owe ya a beer.....

Dont have my radiator yet, and I swapped out the connection on the manifold, so I just wanted to be sure....

I labeled and tagged everything else, even snapped some pics, but for some reason I didnt think of the heater hoses...

Thanks again.
