Hello I'm new to the Forum and trying to find out some info that surely others have run into by now. I have a 98 F-150 with a 4.2 V6 and have come across a part that is corroding badly in the Heater/Coolant System. I can't find a part to replace a straight metal pipe or tube that comes out of the front of the lower intake manifold and connects to a heater core hose. The pipe exits the front of the lower intake manifold just above and to the right of the thermostat housing. There is a 90 Degree pipe that comes off the top of the manifold that is available but I don't see where anyone even acknowledges that the straight pipe even exists even though it is visible in the same photo's they use to sell the 90 degree one. Has anyone else ran into this problem and found a supplier for this part?
