2005 truck 5.7 WHERE DOES THIS HOSE GO

[loganscuda]

I’m installing my AC and I have a hose looped on the water pump for heater hose. Which hose goes to the heater. Is it the one that comes from the block with the tube or is it the one off the pump. I’m so confused.......if it had 3 hoses I would be a part time electrician. Google is no help.

5.7 hemi truck engine should have 2 heater hose connections by the lower rad hose inlet. There should be a heater pipe that wraps around the ft. of the water pump witch would connect to the upper heater core hose, and a shorter pipe threaded in witch connects to the lower heater core hose.
