Which heater hose that comes from the firewall goes to the water pump.The top outlet or the bottom outlet?
There R 2 outlets for the heater hoses coming out of the firewall.
1 outlet on top & 1 outlet below the top one.
Which one goes to the block?
Thanks for your answer
If they are not labeled INFLOW / OUTFLOW. It doesn't matter. You have a pass thru core.
AgeeKustoms is correct. One hose is supply and the other is return. If you can see a valve on one of the hoses, that is supply to heater core.
