It's the same kind as a 2004 Red Line model.
There isn't one. You refill the coolant with by putting more dexcool (DO NOT USE THE GREEN STUFF (ethalene glycol) ) in the coolant overflow bottle.
There is no timing belt. Saturn Ion's use a timing chain.

yes
regular green stuff
All Saturn Ions use Ecotec engines, which use a timing chain.
To add antifreeze to a Saturn Ion, locate the coolant reservoir, which is typically a translucent plastic tank near the engine. The reservoir cap is usually labeled with a coolant symbol. Make sure the engine is cool before opening the cap, then pour the appropriate antifreeze mixture into the reservoir until it reaches the "full" line. Always check your owner’s manual for specific recommendations regarding the type of antifreeze to use.
use a 10mm wrench and remove the battery from the trunk compartment, and replace it with the new battery
No, from talking to repair shops and a dealer about my own Saturn Ion-2, I have learned that it does in fact use an interference design.
The 1999 Saturn engine uses dexcool type coolant. This coolant is different form other types and cannot me mixed with another type.
