Coolant Reservoirs

Coolant Reservoirs

Coolant reservoirs, also called expansion tanks or overflow bottles, maintain a pressurized coolant supply that the radiator draws from as the cooling system cools down after engine-off. A cracked or leaking reservoir causes coolant loss and eventual overheating, while an upgraded billet or aluminum tank improves appearance and durability in performance engine bays.Popular UpgradesAluminum and billet coolant expansion tanks for LS and LT engine swaps and popular domestic performance vehicles are the most popular upgrades, providing a clean look and superior durability compared to factory plastic bottles that crack from heat cycling. Universal inline overflow tanks made from polished aluminum or anodized billet are popular on custom engine bays where the stock location has been eliminated. Direct-fit OEM-style replacement tanks restore coolant system function on high-mileage vehicles where the factory tank has cracked or the cap seat has deteriorated.How do I know if my coolant reser...
