How do you troubleshoot inoperative headlights on an 81 Buick Regal?

Theres a couple things you need 2 look at. First, check your fuse box and make sure your fuse for your headlights isn't blown. Next check your grounds and make sure you have a good connection. Regals are equipped with a fuseable links that run from the battery to your starter solenoid. Its just a wire that usually melts when there is an overload in the system. Check these wires startin at the battery and visually inspect them to the starter. There should be 2 of them, one runs your system electrical and the other is for your headlights. If either is damaged in any way replace it. (your local parts store should carry these for less than 10 bucks) Im 95% sure this is your problem. If the lights still don't come on remove your light switch and run a wire directly from your battery or a 12v power source to the first wire on the switch. Experiment with the switch by turnin it on and off and use a test light 2 see if power is being diverted 2 the other prongs on the switch. One of these is sure 2 b your problem.

How do you replace a heater core on a 2002 Buick Regal LS 38 engine?

The best way to find out is go to your local library to borrow or auto parts store to buy, ask for a haynes or chiltons manual on your vehicle. This will tell you everything you need to know about working on your vehicle. Not a fun job, takes time and alot of patience. This really doesn't give any information on how to do the job but where to get the best source for good information.

How do you change struts on 1998 buick regal?

Depends on whether or not you wish to replace the whole strut assembly (w/spring and bearing) or just the cartridge. A rule of thumb that I use is IF the car has had more than 80,000 miles or more and its the first time your are replacing them I would replace the whole strut. I just did this to my 1998 today. We have 83,000 miles on her and The springs may be getting weak. I was able to pick up a set of monroes for 140.00 Bucks for the pair on Amazon Great deal. If you are going to try and do just the cartridge, the cool thing is you can do this from the engine compartment without even jacking up the car. You will need a GM strut removal tool that can be rented or loaned from autozone or the like. You may have to remove the hood possibly because the length of the cartridge may be too long to clear the hood in the opened position. Again I find it easier to just replace the whole strut assembly because:

1. You Get a new spring (forget the rumors about the spring quality from china stuff its BS)

2. You get a new upper steering bearing

3. New spring isolator pads

4. New contamination accordian boots (seals out dirt from the strut shaft)

FRONT>Replacing complete strut

A: You have to first jack up the car part way and remove wheel lugs

B: Place jack stand under car in proper area for safety

C: Remove tire and wheel (I do one side at a time, you can do both if you want)

D: Take note of where the brake line and ABS sensor modules are.

(becareful not to let the strut damage or let the brake rotor assembly fall and damage these)

E: There are two large bolts that hold the strut to the steering knuckle 3/4 inch socket

F: After removing nuts you have to use a 2 pound sledge hammer to knock out the bolts. They have a hammer tip to them so you wont damage the threads. Be carefull that you hit them square none the less.

G: Remove the three nuts at the top of the tower(1/2in. or 14mm I think) (DO NOT REMOVE THE LARGE CENTER NUT!) As you remove the last one grab onto the strut so it doesnt fall and damage anything.

H: Remove strut assembly from steering knuckle (You may have to wiggle and lift it to clear the knuckle bracket.

I: Get new strut assembly and fit it back into the tower in the same orientation.

Put on 1 or 2 of the small nuts at the top of the tower but leave them loose for now.

J: Put in the two large bolts after you get the strut lined up to the knuckle.

You may have to loosen the sway bar link bolt to get the holes to line up. Depends on how worn the are.

K: Tighten everything up and your ready to go to the next side.

Oh and remember to put your Tires back on ;^)

What kind of engine coolant does Buick LeSabre 1997 need?

The GM vehicles use the DexCool anti-freeze.

There is a replacement type of antifreeze that can be used in GM vehicles but you cannot mix them with the DexCool. To change to another type of antifreeze the cooling system should be completely flushed of the old coolant.

I would advise keeping the same coolant as the manufacturer provides

How do you access the bulb in the collision avoidance light on a 96 Buick Regal 4 door?

I have been in the car repair business for over 50 years and this is the first time I have heard of this light. I would imagine it is the tail light and you have to get to the back of the light to change the bulb. If you can't get to it through the trunk, the light has to be removed.
