2003 Ford Windstar Intake Manifold Parts Questions & Experts Answers

• Q: How to service the lower intake manifold on 2003 Ford Windstar?

  A: Service of the lower intake manifold starts with draining a portion of the cooling system. Disassemble the upper intake manifold, fuel injection supply manifold along with disconnecting the EGR vacuum hose before loosening the EGR-to-exhaust manifold tube nut. The procedure requires heater hose and upper radiator hose disconnect while separating the intake manifold runner control (IMRC) electrical connector followed by careful placement of the bypass tube. Take out the bolts from the lower intake manifold while paying attention to where the six longer bolts should be placed. The IMRC should be removed when needed and the lower intake manifold sealing components need to be discarded while the gasket sealing surfaces require cleaning with metal surface cleaner. As a part of installation install the lower intake manifold seals which should receive a silicone gasket and sealant bead on their mounting surfaces. Position the lower intake manifold immediately after installing its gaskets since sealant application should not exceed four minutes. Begin by attaching silicone gasket and sealant to the lower intake manifold mounting areas before installing it and fastening the six long bolts then the eight short bolts. Implementation of lower intake manifold bolt tightening occurs in two stages: beginning with 5 Nm (44 inch lbs.) then moving to 10 Nm (89 inch lbs.). You should proceed by connecting the IMRC followed by water bypass tube reattachment and bolting the assembly point. Connect the IMRC electrical connector with the upper radiator hose along with the heater hose and EGR-to-exhaust manifold tube and EGR vacuum hose. Complete the installation sequence by filling and performing a bleed process on the cooling system after you place the upper intake manifold along with the fuel injection supply manifold.
