Understanding the Radiator Cap in Your Volvo S90

The radiator cap is a critical component of the cooling system in your Volvo S90. It serves not just as a cover for the radiator, but also as a pressure valve that maintains the system's pressure at a certain level. This helps prevent boiling over and ensures the coolant flows properly throughout the engine.

Signs of a Faulty Radiator Cap

A malfunctioning radiator cap can lead to overheating, coolant loss, and potential engine damage. Common signs that the radiator cap may need attention include coolant leaks, an overheated engine, or a collapsed radiator hose. If you notice any of these symptoms, it may be time to inspect and possibly replace the radiator cap on your Volvo S90.

Choosing the Right Radiator Cap for Your Volvo S90

When selecting a new radiator cap for your Volvo S90, it's crucial to choose one that matches the specifications recommended by Volvo. A cap with the correct pressure rating will ensure the cooling heating system operates effectively and safely. Using a non-compatible cap can lead to significant issues, including engine overheating.

Installation and Maintenance

Installing a new radiator cap is typically a straightforward process, but it should be done with the engine cool to avoid burns from hot coolant. Regular checks of the radiator cap and the entire cooling system will help you catch any potential issues early and maintain the performance and longevity of your Volvo S90's engine.

The radiator cap has a return valve installed that allows air in from the atmosphere or coolant from the expansion tank if you have one installed.
