Ive looked several places to find the information I need and haven't been able to find it. I'm having to replace the intake manifold on my truck. It's a 2001 super crew lariat with the 5.4. I'm looking for "directions" on how to take everything apart and replace the manifold and how to put everything back together. Any help is greatly appreciated.
1-bleed off fuel pressure
3-disconnect all vacuum hoses and both heater hoses
3-disconnect both fuel lines and air intake ducts
4-disconnect throttle linkage and battery neg. connector
5-remove egr tube
6-disconnect all wiring connectors
7-unbolt manifold and remove it
8-thoruoghly clean all gasket surfaces
9-install new gasket
10-reinstall manifold and torque to specs.
11-reverse dissassembly procedure and refill with coolant.
12-change engine oil before starting

its kind of a bitch to disconnect the fuel lines. in fact i am not mechanical but once i got the fuel line disconnected everything else was easy. you will need a special tool thats a few bucks and a lot of patience, also some deep creep or wd40 to spray into the fitting
once you get the intake off might as well replace the plugs since it will be simple and easy. but becarefull not to strip the threads. i also replaced the coils and the injectors while i was in there. a local shop wanted 350-400 for labor since i did it myself i put that money in to new parts.
i have never done anything like this before and was able to do it so go for it.
also- the new intake (dont remeber who made it, i think dorman) looks total different than the original but works perfect with the gaskets already installed
