  Q: Why is cleanliness important during engine repair procedures, and what are the steps involved in removing and installing the intake manifold on Ford Windstar?

  A:

  Engine failure emerges from foreign materials that enter oil passages and coolant passages together with the Oil Pan when repair procedures fail to maintain appropriate cleanliness. To begin start with draining part of the cooling system fluids while also removing both the upper intake manifold and the fuel supply manifold. The EGR vacuum tube and the EGR-to-exhaust manifold tube should be separated through the process of loosening their respective nuts. The first step to disconnect the heater hose requires compressing the fitting while pulling out the hose. Second, disconnect the upper radiator hose after relocating the clamp. Remove the Intake Manifold Runner Control (IMRC) then place the water bypass tube next to the workspace before unscrewing and removing bolts from the lower intake manifold while keeping track of the location of the six long bolts needed for future installation. The IMRC should be removed when necessary along with all lower intake manifold sealing components after their discarding. First install the front and rear end seals of the lower intake manifold by putting sealant on their mounting points before adding the intake manifold gaskets and the IMRC depending on requirements. The lower intake manifold needs to go into position within four minutes of applying sealant to the mounting points where a bead of sealant will go before putting the manifold in place and tightening bolts to correct specifications. Use first a torque wrench to tighten the bolts to 5 Nm (44 inch lbs.) followed by a second torque to 10 Nm (89 inch lbs.). The water bypass tube should be positioned correctly while installing its bolts followed by connecting the IMRC electrical connector, upper radiator hose, heater hose and EGR to exhaust manifold tube using the nut then hooking up the EGR vacuum tube. Install the fuel supply manifold followed by the upper intake manifold then perform the process of filling and bleaching the cooling system.

  Q: How to service the lower intake manifold on 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.
