Genuine Pontiac Sunrunner Coolant Reservoir

The Pontiac Sunrunner Coolant Reservoir is designed to capture and store fluid that expands from the engine so that it can be fed back into the radiator. This essential system prevents the engine from overheating, giving the driver peace of mind. This Coolant Reservoir is made from heavy-duty molded plastic rather than simple catch bottles, and clear level graduations allow anyone to check fill status at a glance, a convenience that is appreciated across all Pontiac trim. It doesn't matter what year your Sunrunner is, convertible or hardtop, since drivers' Coolant Reservoir uses the same mounting points and hose routing as your Sunrunner. The component has two factory configurations, an overflow type or a pressurized expansion type. Each Coolant Reservoir version fights air pockets that corrode metal and also prevents coolant glycol from getting dumped on the road. Overflow systems utilize a radiator that contains a pressure cap, which allows for the expulsion of excess fluid into the Coolant Reservoir until a vacuum is generated that draws it back in again during cool down. On the other hand, sealed expansion systems have a Coolant Reservoir that carries the cap, is situated higher than the radiator, and offers tighter control that Pontiac enthusiasts appreciate. The safety in both layouts is enhanced because the engine is kept full and free of air, improving fuel economy and extending the life of all Pontiac SUV powertrains. Having a cleaner driveway is yet another added benefit. The Coolant Reservoir prevents messy overflow and traps vapors. But one that solidifies Pontiac's image of the nimble Sunrunner. The strong materials are capable of enduring the heat cycle of off-road excursions and city trips, proving once again why the Sunrunner gets such solid praise for reliability with a well-sealed Coolant Reservoir. The single component may look basic but it plays an important role in the overall cooling system. Any Pontiac with the Sunrunner badge provides stable performance, confident efficiency, and peace of mind when out on public roads.
