Dorman Engine Coolant Recovery Tank Cap

The Dorman engine coolant recovery tank cap, also called a coolant reservoir cap or overflow tank cap, seals the coolant recovery system and keeps it at the correct pressure. A worn or damaged cap can cause coolant loss, overflow, or overheating. Replacing it helps restore proper cooling system operation.

Key Features:

• Seals the coolant recovery or overflow reservoir to hold system pressure
• Pressure-relief design vents excess pressure and lets coolant move between the radiator and reservoir
• Durable construction resists heat, pressure cycling, and exposure to coolant
• Designed to replace a cracked, leaking, or worn original cap
• Simple installation with no special tools, by twisting or pressing the cap onto the reservoir neck
