The air compressor is located above the rear axle on the passenger side
Where is a right sound insulator located on a 1989 cadillac sedan deville?
Under the the dash of the passenger side inside the car.
In a word, no. The Northstar engine is a DOHC 4 valve-per-cylinder engine, while the LSx is a traditional pushrod engine. The ports of the northstar are wider to accommodate 2 intake valves, the ports on an LS are narrower and tall feeding a single, large intake valve. The heads on a Northstar are wider and therefore the valley is narrower. The starter on a Northstar is located in the valley. All of these attributes dictate the design of the Northstar intake manifold which, looking similar on top, is very different than an LS manifold on the bottom.

Then it is obvious the gas cap was not the problem. You need to have the codes read and see what code you are getting. Use that code to help diagnosis the problem.

What is the problem with the Cadillac 4.1 liter engine for 1983?
common problem was with cylinder heads, and gaskets. Initial results, were overheating, missing, mixing of coolant and engine oil will look like mayonnaise. Good way to see early indicators is to remove the oil filler cap and inspect. If its white and creamy, get ready for major repairs
I have two 4.1s. one is in an 83 coupe and the other in an 85. If you keep the oil clean and don't over heat the engine you are find. The 83 took me to las vegas from
wisconsin on three occassion with plenty of power and average 25 miles per gallon. The 83 coupe is past 200,000 and the 85 is just broke in at 116,000. I have a 97 cadi
with the 4.6 northstar and would gladly trade for an older cadi with the 4.1.

Where is the location of the engine computer of a 1997 Cadillac Deville?
drivers side under the air filter box housing under the hood once you remove the air cleaner box its in a sealed black abs box
It sounds like a bad valve could be the problem. If it misfires out the exhaust,exhaust valve,If it misfires out the intake ,intake valve. When it warms up the metal expands and closes up the opening some in the bad spot and it will run better. You can try disconnecting the plug wires one at a time while running (Use an insulated tool or you will get shocked) to try and isolate the cylender that is bad. It will be the one that the engine sound does not change when you disconnect the wire. Then take out the plug and then do a compression check on that cylinder ,should read about 110-125 PSI. if its much less its a burnt valve. Or take it to a garage and have them put it on a machine that will tell you which cylender is giving you trouble.
Fuel filter 88 Cadillac deville?
I'm assuming you want to know where it's located. It's at the rear of the vehicle on the driver's side along the rear fender. It looks sort of like a can of pop. There'll be several lines running along side it, these are brake lines and fuel lines. The fuel line going in and out should just be bolted in, so they can be removed with wrenches. But lubricate the threads first, because on a car this old and given the location, everything will be rusty and potentially weakened. You don't want to have to repair a broken fuel or brake line if you don't have to.
How do you add coolant in a 98 deville?
Coolant for the 98 Deville is added into the coolant overflow bottle. The side of the bottle should have low and high coolant markings.
My 1998 Deville Concours had a blown blower motor for the heater/ac unit. I had to replace it because it stopped working likely due to age (replaced in 2008) and it was filthy when I took it out. Hard to do this by yourself but it can be done if you remove the obvious things in your way underneath the hood. Good luck! The blower motor fans cost around $130 ish.
