Hi,

I've got a 99 5.9l 2WD - can someone tell me the correct position for the heater pipes i.e. does the pipe that leads from the water pump go to the higher or lower connection on the firewall for the heater core, if indeed it matters...

I believe the top hose takes the quick turn and the lower goes to the pump. I just messed with my hoses on thursday. But I don't think it would really matter, could be wrong though....

 

infact I'm almost 100 percent sure top turns lower to pump
