What would cause a 95 sedan deville to make a very noticeable knocking sound that gets louder as you drive?

I have a 1995 Cadillac Deville, 4.9 engine also, I believe the problem is the oil pump is going bad and the oil is not being properly pressurized. I've already replaced the oil switch located above the oil filter on the engine block, but you have to remove the air filter holding unit first to get to it. As soon as I find someone who can replace mine at a reasonable cost, I'll let you know if that was the problem. Also don't forget to check your oil level first. This engine only holds 5 quarts of oil in the engine alone, and another 1/2 quart in the oil filter itself. Totaling 5 1/2 quarts. Good Luck!

How do you change the rear turn signal light on a 91 Cadillac Coupe DeVille?

You need a T-15 star bit driver that is referred to as TORX. On the top and bottom of tail light are the screws. Carefully remove the chrome trim then the light pulls out after applying slight upward pressure. Once you twist out the socket the bulb simply unplugs. It should be either a 3057 or 3157 bulb. (i cant remember for sure)

What is wrong if a 96 DeVille misses bad when accelerating slowly and keeps missing until the passing gear kicks in but idles okay?

I just repaired mine with exactly the same problem. Replacing the spark plugs and wires is all it took. Be sure to use only the correct platinum plugs and an exact OEM set of wires. My replacement wires and factory wires were all numbered on the jacket... making things very easy. Note: the distributor cap is numbered as well. Car runs great and I am getting about 4 MPG's better.

How do you replace a serpentine belt on a cadillac deville 1994?

Probably one of the most simple maintenance jobs a do-it-yourselfer can perform...

The only tool needed is a 1/2" breaker bar. To the rear of the power steering pump you will see a belt tensioner that has a square cutout that the breaker bar fits into. Pull the breaker bar towards the front of the car (or up) and the tensioner will move so you can pull off the old belt. Pay attention to the routing of the belt--make a diagram if the decal is missing from the underside of the hood! Put the new belt in place, use the breaker bar to again move the tensioner and slip the belt under it. You're done! Takes all of maybe ten minutes.
