URO GM0618638 Coolant Expansion Tank Cap Replacement

The URO GM0618638 Coolant Expansion Tank Cap is a replacement coolant reservoir cap (also called a coolant recovery bottle cap). It helps restore proper pressure to the cooling system and seals the expansion tank.

Key Features:

• Direct-fit replacement design for the coolant expansion tank
• Secure fit that helps prevent coolant leaks and pressure loss
• Helps hold correct cooling system pressure, which helps prevent coolant loss and overheating

A worn cap can lose its ability to hold pressure. Replacing it promptly helps keep the cooling system working reliably.
