SOURCE: own a 1997 mercury grand marquis. went to change

The 4.6 does not have an traditional distributor. This year engine should have two coil packs located on the front of each valve cover. Each coil pack controls four cylinders. Some of the plug wires will cross over the front of the engine in a wire loom on top of the alternator. The spark plugs are located down in the intake manafold. they run beside the fuel rail on each side of the intake manafold where it joins to each head. You will need an extention at least 8 to 10 inches long to get at the spark plugs. The plug wire fit snuggly into the intake manafold and have an extention on them that connects to the spark plug.

SOURCE: where are the spark plugs located on a 2000 Mercury Grand Marquis

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.

I have a 1991 chevy lumina with a 3.1 v6 engine. I am trying to replace my freeze plugs but i can't locate them. Where are they located?


Which ones? There are several. There are 2 or 3 freeze plugs on each side of the engine block. There are 2 freeze plugs on the back of the block between the engine and the transmission and there is one in each cylinder head. Freeze plugs can be very difficult to change properly with the engine still in the car unless you vave the correct tools and equipment to get the job done. They can be very tricky getting them in correctly when you DO have the proper tools.

I need to know what the stock compression pressure in psi should be on a 1991 mercury grand marquis 302 5.0L, I dont want the ratio, I need the psi. What was it from factory?


This engine offered a 4-inch bore, 3-inch stroke and a compression ratio of 8.9 to 1.

each cylinder should have the plugs removed, and each cylinder should have atleast 150 psi, with no more than a 10% difference between the 8 cyl .

most engines period will cary atleast 90 to 180 psi depending on the number of cyl.
