    There's 2 coolant sensors in the 96-2000 L31's. Use the green 1 wire sensor but I'd recommend tapping the head if you want a true temperature reading. The adapter sticks out so far that you'll see a 10 - 25 degree difference.

    put some grease on the drill bit to catch the chips as you drill the hole. Take a vacuum and suck the chips out that go into the engine. Same with the tap, coat it in grease and thread it.

    Yep, you can do it with a 90 degree drill if you have a steady hand. LOL

    Yep, thats the one you should have been using. Save some engine money for an eye exam.
