I have a 2002 496 Mag...I found 2 6mmx40mm bolts under the engine and can`t find where they go..They have threads up about half way..
Also the thing is loosing antifreeze somewhere..Have to refill resovoir everytime i go out..Help Pls???

Sounds like they might be exhaust bolts for the water rails. Can't really remember how big 6mm is but a good start. The antifreeze leak is probably your heat exchanger leaking at the bottom where the exchanger fits into the elbows on the cylinder head. Seems like thats the place everyone else is finding the leak.

If you have any questions feel free to email or call the shop. Ask for John S.
