This answer was rated:

I need to replace the starter on my 93 Buick Regal. It's a 3.8 L, automatic. I am a very poor mechanic. Can you give me some pointers on this specific model? Thanks. Vic

Hi Issac, This information is for the 3.8L motor which is the most popular in your car. If you have something else, just let me know and I will try to pull it up for you. Good luck with it and thanks.

    Bob, Thanks for the detailed answer, but I don't know if I can actually do this. Believe me -- I'm pitiful, but can't afford to take it to the shop. Please give me a very general idea and tell me like you're speaking to a 10 year old! Thanks. Vic
    Hi Issac, These are not among the easiest to do, but it is still pretty basic. First thing to do is to unhook the battery. Then you will need to remove the radiator cooling fan on the drivers side of the radiator, you are going to need it out of the way so you have clearance. It is just a matter of unplugging the motor and removing the upper and lower bolts that go through the ends of the housing and hold it to the body of the car. Then you will want to disconnect the wiring (again for room) of the knock sensor, one wire, knock sensor is screwed into the front of the block. Also the oil level sensor in the front of the oil pan needs the wire taken off of it. Then you will need to take the retaining bolts out of the cover that goes under the fly wheel and remove the cover. Then unhook the wires from the starter solenoid. The big terminal that holds the battery cable and the small one that has the little wires to the solenoid. After that it's just a matter of taking out the bolts that hold the starter on the car and removing it. Just print a copy of the instructions so you have them when you go back together with it. Thanks
