Just getting the last few things together, going to be installing my engine soon. I need to know which line takes the hot water to the heater core and which is the return. Plus any install tips would be nice. My truck is sitting on 35's so installing the motor will be fun.

 

Let the air out of your tires.......

The line closest to the passenger side is the inlet. (the one closest to the center of the truck is the outlet.)

 

The easiest way I've ever found to install an engine was with a gantry hoist (rather than a cherry picker). It's pretty slick to be able to go under the truck and still control the engine's placement.

 

10-4 thanks for the advice.
