Supercharger Coolant Tank

What Is a Supercharger Coolant Tank?

Supercharger coolant tanks are a critical component in any air-to-water intercooled forced induction system. A supercharger compresses intake air to force more of it into the engine, but that compression process generates significant heat — heat that robs power and, left unchecked, can damage engine components. The coolant tank serves as the fluid reservoir for the supercharger's dedicated cooling loop, storing and circulating coolant through the intercooler to pull that heat out of the compressed charge air before it enters the combustion chamber.

Why Upgrading Your Supercharger Coolant Tank Matters

Factory coolant tanks are typically made of plastic and sized for conservative, stock-level power outputs. When you add boost or push your supercharged engine harder on the street, track, or dyno, those OEM tanks are often the weakest link in the cooling chain. Plastic tanks are prone to failure after repeated exposure to extreme heat cycles, and their limited capacity means the coolant heats up faster and stays hot longer — a condition known as heat soak.

An upgraded aluminum tank addresses both of these weaknesses. Aluminum construction provides far greater durability and resists warping or cracking under sustained high-heat conditions. More importantly, a larger-capacity tank means more coolant volume in the system, which takes longer to reach critical temperatures and gives the heat exchanger more fluid to work with between passes or pulls.

For serious track and drag strip use, many aftermarket tanks go a step further by supporting the addition of ice or dry ice. Moroso's supercharger coolant tanks, for example, feature a fuel cell-style filler cap and a filtered outlet strainer that allows the tank to be packed with ice for maximum cooling during timed runs or dyno sessions — a straightforward way to lower intake air temperatures and unlock more consistent power.

Key Considerations When Shopping for a Supercharger Coolant Tank

• Fitment: Most tanks are application-specific. Confirm the tank is designed for your exact year, make, and model and that it mounts in the correct location — many replace the battery tray, so a battery relocation kit may also be required.
• Capacity: Larger volume helps delay heat soak. Consider how you use the vehicle — street driving and extended cruises benefit from a well-sized tank paired with a quality heat exchanger, while drag racing setups can take full advantage of high-capacity ice tanks.
• Material & Finish: Aluminum is the standard for performance applications. Look for TIG-welded construction and consider finish options — many tanks can be polished, chromed, or powder-coated to match your engine bay aesthetic.
• Ice Compatibility: If you run at the track or dyno, a tank with a wide-mouth filler opening and a built-in screen to protect the pump impeller is a major advantage.
• Installation: Bolt-in designs that reuse factory hose connections make for a cleaner, more straightforward install with no cutting or welding required.
