I am replacing my coil. I removed the old one and it looks like it is riveted to the back bracket. How do I get it off so I can put the new on that bracket? Please, any info would be great.

 

Go to my Tech Page and look in the "How To's".

 

Thank you, thats just what I needed.

I'm also replacing the knock sensor. Do you have to drain all coolant to do that? I read somewhere that you did.

 

That hole in the block is practically the lowest spot in the cooling system, so coolant is definitely going to come out. You could try to put the new sensor in as fast as you can, but it will be messy (you might need goggles).
