How do you time 92 deville?

Answer 1

This answer assumes that you know how to use timing light.

1. With the engine off and cold, clean off the crankshaft damper pulley where the timing notch is. Then clean off the timing scale so you can read the numbers. (It is usually easiest to remove the plastic fender liner from the right front wheel well so you can reach this area)

2. With the engine at operating temperature (top hose too hot to hold on to), turn off the A/C and then the engine. Attach a timing light to the # 1 plug wire (it's the one in front closest to the fan belt).

3 Loosen the hold down nut at the base of the distributor, enough so it will rotate. The nut is 15mm but very hard to get to, I use a special tool designed just for this purpose. I f you cannot get this tool you will have to remove the air cleaner and maybe other parts to get to it with whatever you have.

4. Under the center of the dash inside the car there is a plug (ALDL) that you must jumper (connect a wire) from pin A to B, leave this in place while you do the next step.

5. Start the engine and set parking brake.

6. Aim the timing light at the timing marks on the pulley you cleaned off earlier and rotate the distributor until the mark lines up with the 10° mark (6° if you are using regular gas). Tighten the distributor hold down nut and recheck the timing (very important will change when tightening).

7. Remove jumper wire from ALDL plug, put back everything you had to remove and you are done!
