Saturn SL1 Replacement Expansion Tank Information


Saturn is an established automobile manufacturer heralded for creating tough and high quality automobiles. A new vehicle needs the best components that are available. Without a Saturn SL1 Expansion Tank on your car, the coolant or antifreeze that is released under pressure would most likely leak out of the car which can be bad for the planet. Your vehicle's Expansion Tank keeps the excess fluid in the cooling system which was forced out of the radiator and returns it after it has cooled off. You should check the level of coolant in the vehicle's Expansion Tank every now and then; significant drops in the antifreeze level could indicate there is a leak in the cooling system. Your car's Expansion Tank is a container that is designed to allow antifreeze and air bubbles within your coolant system to increase in volume due to an increase in temperature.


They are available for the following Saturn SL1 years: 2002, 2001, 2000, 1999, 1998, 1997, 1996, 1995, 1994, 1993, 1992, 02, 01, 00, 99, 98, 97, 96, 95, 94, 93, 92. This part is also sometimes called Saturn SL1 Radiator Overflow Tank. We stock expansion tank parts for most Saturn models including Ion, SL2, Vue, SC2, Aura, SL, SW2, SC1, Sky, SW1, SC and Outlook.

We stock these Expansion Tank brands for the Saturn SL1: Dorman and Genuine.
