About Our Overflow Tanks and Catch Cans

Overflow tanks and catch cans play an important role in maintaining proper fluid control and overall engine system performance. Coolant overflow tanks, also known as recovery or expansion tanks, are designed to capture excess coolant expelled from the radiator as temperatures and pressure increase. This helps prevent fluid loss, keeps the cooling system efficient, and allows coolant to be returned to the system as it cools. 

Catch cans, on the other hand, are used in the crankcase ventilation system to capture oil vapors, fuel residue, and contaminants before they are recirculated into the engine. By separating these contaminants from the airflow, catch cans help prevent buildup inside the intake system, improving engine cleanliness and long-term performance. 

Upgrading overflow tanks and catch cans can improve both performance and reliability. High-quality overflow tanks help maintain consistent coolant levels and prevent overheating, while catch cans reduce contamination, support cleaner combustion, and protect internal engine components.

In addition to functional benefits, these components are commonly used to enhance engine bay appearance. Available in polished aluminum, stainless steel, and billet designs, overflow tanks and catch cans provide a clean, professional look while supporting proper fluid management and system efficiency.

Whether you're upgrading for performance, improving reliability, or refining your engine bay setup, choosing the right overflow tank or catch can helps ensure proper fluid control, reduced contamination, and long-term engine durability.
