Step 1: Clean the radiator Step 2: Place a drain pan Step 3: Remove the radiator pressure cap Step 4: Inspect the pressure cap & hoses Step 5: Drain the radiator Step 6: Rinse the radiator Step 7: Add the coolant and water mixture Step 8: Bleed the system Step 9: Replace the pressure cap Step 10: Clean up. Step 1: Clean the radiator Make sure the engine is cool before you start. Your vehicle's cooling system sucks in air as you drive, which means insects, dirt and leaves can be pulled into the fins of the radiator fan. This condition prevents air from passing easily through the radiator, and can cause your car to overheat. Using a hose with a nozzle, a bucket of soapy water and a soft nylon brush, loosen the insects, leaves and other debris. Gently brush with the direction of the fins of the radiator fan, not against it. These thin metal fins are fragile and can be bent with this action if you're not careful. Follow this gentle cleaning with a gentle stream of water on the front and rear of the radiator. Don't turn up the hose to full pressure--a concentrated blast of water can be actually bend the fins of the radiator. In general, you should clean the radiator fins every 12,000 miles (19,000 km). Don't do it when the engine is hot, cold water can damage a hot engine. Wait until the engine has cooled before you start cleaning. Step 2: Center drain pan under the drain spout Never allow coolant to drain out onto the ground. Its sweet smell attracts animals that will drink it. Don't leave it to drain unattended in a pan for the same reason. Another way to protect wildlife from accidental spills is to use antifreeze that utilizes propylene glycol, instead of ethylene glycol. Antifreeze that is made with propylene glycol, such as SIERRA
Use the Gold antifreeze. It lasts longer and does not cause corrosion to the cooling system.
Match the color of your antifreeze to the new one you buy unless it states its good for all types.
Boil over? As in antifreeze? that's probly a blown headgasket
The Saturn sl2 does not have a timing belt, it has a timing chain. And under most conditions it does not need replacing.
No vehicle actually burns antifreeze. If the antifreeze level in your Saturn seems to be going down, it's because of a leak.Possible antifreeze leak locations are:Coolant hoses.Radiator cap.Water pump.Heater core.Head gasket.Cracked head or block.Find out where the leak is occurring and repair it.

I am prettysure you can change the motor as long as the body structure is the same and you have skill in this sort of thing.
Are you asking how to??
With tools
....Suree. More information is needed
