Does anyone know what the metal tube coming from a 90 in one of my heater hose goes to? 1990 ranger 2.3. After removing the manual trans to replace slave cyl i noticed a small metal coolant line going over trans to the intake side of motor. I cannot see where it ends up or if it is needed. I've never seen this before. I know its a coolant line because it has a pin hole and is leaking. Any help greatly appreciated. The line described comes off of one of my hoses going to heater core.
