Bad Heater Core?
#16
You can bypass the heater hose a few different ways. If you open your hood and look behind your two big fuses on the passenger side. On your firewall you will find two hoses- One comes from the water pump tube, and one goes to the intake. Depending on your truck it will either be an inlet on the front or back of the intake. Both on the pass side. These two hoses need to be connected together. You can do this however you feel necessary.
