it seems there has been a malfunction within your CD Drive, this is what is causing the CD drive to not spin or read the disc. these problems can be only generally resolved by either getting the console repaired/replaced unfortunately.
The PS2 will still turn on and run because the CD Drive does not dictate whether the console works or not, but because the CD Drive is broken, you will not be able to play games or watch DVD Films unless you have the CD Drive Repaired.
NOTE : I would not encourage you to use Anti-freeze on the console/discs under any circumstance, Anti-Freeze is designed to De-Ice Car windows, Not to fix technical issues With PS2's, It is very dangerous !
Hope this Helps ?!
