What grade of gas should be used for 1999 Cadillac Deville?
They say to run premium but mine runs just fine on 87. I did get about 2 miles per gallon better mileage on premium but that's not enough to warrant the difference in cost.
What is wrong with the drivers electric seat work on my 1979 cadillac deville?
Check the Power Seat Control Switch first to see if it is defective and then use a test light to see if it is getting power to the switch.
The Gears that move the seat can break and the seat will not move at all and you will hear a noise.
If the gears are stripped I would recommend taking the whole seat out and you can take the seat off the frame which holds the seat and gears and go to a Salvage Yard and purchase the seat frame with the Power Seat gear box and wires all intact.
I had a mess trying to repair just the gears.
Will 20 inch rims fit on a 95 deville?
Yes they will. Go under the skirt and remove the two 10mm nuts that hold the molding. There are more than two but the two directly behind the skirt should be enough. There shuold also be another bracket under that one. Remove that and jack the car up high enough to catercorner the top of the wheel over that aluminum brake cover while holding the molding outwards SLIGHTLY, dont break it, it can be done! I just did mine two days ago (4/15/10) with 245/40/20 inchvogue tires and it worked!
How do you install a thermostat in a 91 Cadillac DeVille?
The thermostat housing is located on top of the motor, underneath the air intake assembly. The easiest way to remove it, is just take off the air cleaner assembly. Unscrew the plastic nut on top of the air cleaner (above the throttle body), and then remove the 4 screws that hold the top onto the air filter box. It will start to lift off now, but there's several hoses and vacuum lines attached. The rubber hoses should have plastic clips holding them in place, these can be CAREFULLY separated with a screw driver, and then just pull the hoses off. The vacuum lines are underneath it, CAREFULLY pull these off, or pry them off with a screw driver. Make sure you remember which ones go where! With this off, the housing is easy to see, the upper radiator hose on the driver side of the car goes right into it. Remove this hose, be prepared to spill some coolant. Have towels ready to catch/mop up what you spill, and have some extra coolant handy to replace what is lost when you're done. There should be a couple bolts holding the housing on, remove these. There might be a sensor in this as well, I don't remember, unplug it if it's in the way. Pull the housing cover off, and the thermostat should be right underneath. It just lifts out, make sure you put the new one in the same way the old one came out, in other words, don't put it in upside down, it won't work. Also, make sure you have a new gasket for the housing, you should never reuse the old one. If needed, clean of any old gasket material or sealant, try not to get any into the coolant. It's not required, but it never hurts to use some RTV sealant when you put the housing back on. Reinstall everything, add coolant if needed, and don't forget to recheck the coolant level after the engine heats up, it'll probably drop once the thermostat opens up.

How do you remove a vibration damper on an 84 cadillac deville 4.1 lieter engine?
Remove the bolt then you need a heavy duty puller. They are a pain.
How do you replace the water pump on a 1995 Cadillac DeVille 4.9L fwd?
It isn't very hard but you need instruction. Go to Auto Zone and get a shop manual on your car for about $18 and it should have pictures and everything.
You'll need metric wrenches/sockets and 3/8 torx bit set.
1. drain coolant
2. with the drive belt still on, remove the 3 bolts that hold the pulley to the water pump. If the pulley rotates while trying to remove the bolts have a friend use a 1/2 rachet on the belt tensioner to put more tension on the belt so that way you can remove it.
3. take a 1/2 rachet or breaker bar and insert it into the belt tensioner and pull towards the front of the car releasing the tension on the belt allowing you to remove the belt.
4. Remove the pulley and be prepared to get fustrated. there are 10+ bolts/nuts and 2-3 torx bit bolts. The fun part is removing them. There is not alot of torque on these bolts so breaking them loose is not an issue. its not really a problem its more of a hassle. This is where a geared wrench would be real nice. Space is really the issue when you get to the bolts toward the rear, once you get all the bolts just pry the water pump off.
5. clean up any gasket material off the engine block and clean all the threads on the bolts.
6. put a small bead of silicone(rtv) on the both sides of the gasket(although not really necessary) then put water pump/gasket on the block and put all the bolts back in.
7. you should be able to tighten them as much as you can but remember there is not much torque needed, make sure to over all the bolts.
8. put the pully back on and tighten the pulley bolts and put the belt back on and tighten the pulley bolts again.
9. fill up on coolant
Here's more input from another FAQ Farmer:
- I just changed mine on my 94 Deville and it was not too bad. It has the 4.9 liter. First, get a replacement pump. Please note the importance of not removing the two bolts holding the timing cover to the water pump inlet cover. They are to the right and below the pump. After draining the radiator, remove the strut-to-core support brace, the battery, and finally the coolant recovery tank. (note: horn has to be removed for the recovery tank to clear the A/C receiver/dryer) Then carefully feel around the pump and count all the fasteners. I actually layed the new pump in front of me while I worked. While the belt is still on the motor, loosen the 4 drive pulley bolts on the pump slightly but don't remove them yet. Now you can take note of the serpantine belt path and remove it from the car via a 1/2" drive ratchet on the tensioner. Next, remove the drive pulley you loosened earlier. Now remove all the bolts and nuts holding the pump on the timing cover. I believe I used a 1/4 drive 10mm, 15mm socket, and a T45 or T50 Torx wrench. After all are removed, carefully removed the pump via a putty scraper and a little force taking note not to damage the timing cover, as this will result in a leak. After removal, carefully clean the cover of any and all stuck gasket and wipe dry with a cloth. To prepare the new pump for installation, adhere the included gasket to the pump with liquid shellac gasket compound. This holds the gasket in place while you install the pump in the tight space. After coating the other side of the gasket and lining the pump up with the engine, start two bolts to hold it in place. Go ahead and force it in place and start and finger tighten all the remaining bolts and nots. Then torque in this sequence: Torx and 15mm headed bolts - 30ft lbs. The 7, 10 mm hex nuts - 5 ft lbs. The 7, hex head bolts - 5ft lbs. Next, install the pump pulley as tight as you can and then install the belt and final tighten the pullet bolts. All remaining steps are just the reverse order.
Use high tack instead of silicone. Its much cleaner and goes on more evenly.
Where is the turn signal flasher located on a 1997 Cadillac Sedan De ville?
I have 2 98 devilles. I couldn't find mine either. I listenned to the one that works. I FOUND IT! Sitting in the drivers seat is is under the panel just above your left leg. You have to stand on your head and reach up under that panel. There is a clip on the flasher that holds it in place push up on the unit it is somewhat covered by a piece of foam rubber. Hard to see the unit is pointed up with the wires pointing down.It will release off the panel and fall in to your hands. Then separate the connection to the flasher. Reinstall new. The one I bought does not have a clip so It won't be remounted up under the dash.

How do you change starter on 1996 sedan deville?
Changing the starter on a 1996 DeVille sedan can be a little complicated for beginners. The intake manifold will need to be taken off the car before the starter can be removed. After the manifold is removed, the starter can be taken off. The wires will need to be taken off the existing starter and labeled or taped for the new starter. The start is held in place by two bolts and after the bolts are removed the old starter can be removed.
