Rear coolant lines
Hello friends, I have a question..I have a 99' F-150 with a 4.2. Replaced the intake manifold gasket, and found myself trying to figure out which coolant line goes where on the upper plenum rear connection, on passenger side. The pics I took werent to good. Thinking the upper one goes to the connection near the heater hose connection near thermostat, but not sure. Your help would be muchly appreciated.
