How hard to change spark plugs on the 1993 Corsica 6 Cylinders 191 T 3.1L MFI?
Do I need special tools? I can change the spark plugs on my 4 cylinder Saturn in 15 minutes. That is all I can do on the car, so you see I'm not an experienced engine guy! :-)
Is there any manual on the web?
thnx

the easyest way iv found to change the plugs on most older front drive chevys is to unbolt the top motor mount (the one that looks like a dog bone) then gently! jack the car up at the back of the motor (tipping the motor forward) then u can get in behind the motor to get at the back 3 plugs. the front three are easy anyway so thry it and see what happens.

 

You don't need any special tools. I put plugs in a 91 and didn't have to much of a problem. You should be able to reach over the top of the engine to get the back plugs, with a 3/8 rachet, spark plug socket, and maybe a short extension. It has been a while. If you don't rush you should be fine.
