Genuine Saturn SW2 Radiator Cap

The Saturn SW2 Radiator Cap prevents boiling over in the cooling system by maintaining proper pressure, keeping the coolant in liquid form at higher engine temperatures. The Radiator Cap threads on to the radiator neck allowing the spring valve to hold the set pressure and vent the overflow to the reservoir before the hoses swell or rupture. When the engine cools down, a secondary vacuum valve inside the Radiator Cap opens, allowing fluid to draw back and keep that hose from collapsing. It's a little thing that helps Saturn drivers feel confident on long trips. The Radiator Cap fits all generations of SW2 models, from the first lot of the early nineties to the later SW2 models with clamshell access. This is because it offers the same dependability without any fuss. The metal shell resists heat warping while the elastomer gasket seals tightly. A knurled grip allows drivers to remove the Radiator Cap when temperatures cool. Because the rating is in conformity with Saturn cooling specifications, there is no need to make any modifications in the installation of the Radiator Cap on any SW2. Regular maintenance is easier because of the Radiator Cap, which also protects the aluminum head from steam pockets. Drivers experience improved overall fuel economy, as the unit is a sealed system enabling the thermostat to regulate the heat efficiently. The cap is also extra safe, as a warning label reminds the driver to wait before opening. A wisp of coolant smell is an early indication that an aging SW2 cap needs replacing. With this in mind, many owners keep a spare cap handy to avoid drama on the road and to protect their Saturn. These simple prevention aids the strong reputation of Saturn cars, especially the versatile SW2, for longevity and affordability in a crowded market. Using a genuine Radiator Cap ensures your Saturn is ready for hundreds of miles.
