Ford / Lincoln /Mercury
4.6L Intake Manifold Repair

Tools & Supplies

You can save yourself some time and frustration if you get the tools and supplies you'll in order before you get started on the actual repair work. Most of the tools you'll are common-place and you probably already have them in your toolbox. For the less common items you'll need (like a torque wrench) you can probalbly borrow/rent them from your local auto parts chain. AutoZone and Advanced Auto Parts both have a tool loaner program in most areas.

• 13mm wrench
• 19mm wrench
• 3/8" drive ratchet
• 1/2" drive ratchet
• 3/8" drive extension
• 8mm socket
• 10mm socket
• U-joint socker adapter
• Torque wrench
• Flat-blade screwdriver
• Adjustable (Crescent) wrench
• Teflon tape

• WD-40
• Paper shop towels
• Antifreeze (2 gallons)
• 5/16 allen wrench (2001 and up models)

• Spark plug socket & new spark plugs
• New water pump
• Carb cleaner (Gumout, etc.)
• Palm-sized combo 1/4" - 3/8" drive ratchet (highly recommended)
• Mechanics gloves (highly recommended)

Caution - Make sure that there is no fuel pressure present in the fuel rail before beginning the repair. We let our test car sit for several days (waiting on the intake to arrive) and there was no residual pressure in the fuel system. There is a Schrader-type valve in the fuel rail that can be used to de-pressurize the system if you have the necessary equipment. The easiest and safest way is to disconnect the fuel pump relay and crank the car for at least 15-20 seconds. Some Fords also have a fuel cut-off (rollover) switch in the trunk. This switch can also be used to disable the fuel pump before cranking to de-pressurize the system.

Looking Under The Hood...

The picture below will help you familiarize yourself with some of the components you'll be working with. These are pictures from a 1997 Mercury Grand Marquis but the items look similar on many of the other modesl. Some newer models have a plastic cover or "shroud" that hides the top of engine. Once removed, you'll see a similar picture to the ones below.
