Your 1990 Cadillac Sedan deville 4.5 v8 has a dead battery and the hood release will not release and you need to know how you can open the hood?

Why does my 91 Saturn automattic transmission drag or shift hard it had been overfilled too?

overfilling can cause high pressure inside the transmission valve body and can accually damage the solenoids that control shifting. if the solenoids have gotten weak, they can cause the transmission to hold shifts longer then it should, or not shift at all. try changing the transmission fluid completely. there is a 15mm drain plug on the bottom of the transmission. the transmission holds 3.75 quarts with a new filter. if this does not solve your problem, you may have to replace your solenoids, which can get quite costly.

How do you change a front wheel bearing on a 1991 cadillac deville?

that's fun.....not. first you'll need the socket to take off the cv joint nut, which is the very big nut nut in the center, that socket is about a 42mm i believe. you have to break that loose. then lift the vehicle from that side and remove the tire. after that remove the breaks, includes caliper and disc. your wheel bearing is a wheel HUB. its a whole assembly. with all those items off that's what your left with. there are three bolts that are holding the hub to the knukle or spindle. its either an Alan wrench type or a star type bolt. after that you have to break loose the CV joint, to do that take the big nut and unscrew it until its at the end of the screw now take a hammer and hit the nut inward so tha the cv joint slides in thru the knuckle then you can remove the hub and replace it. installation reverse. for the cv joint just tighten the bolt to pull it back thru. that nut has to be torqued which means there has to be so much punds of pressure on that nut. it should be about 80 lbs.

Will 24 in rims fit on a 1996 impala?

Here in Florida, we can make ANY rims could fit on ANY car. In order for it to look clean without a massive lift you can slap on some 24's with 275/25/24 tires (rubber bands) and you'll been floating through your city. Plus, they'll be tucked nicely.
