Supercharged 4.6L Mustangs generate heat that the factory plastic coolant tank simply cannot handle long-term. Moroso's aluminum coolant tank mounts in the battery location, reclaiming that space for a high-capacity reservoir built to survive repeated heat cycles without warping, cracking, or failing under pressure.
Fabricated aluminum construction. The factory tank relies on plastic that softens and fails after sustained exposure to supercharger heat. Moroso replaces it with an aluminum unit that holds its shape and seal through the kind of thermal stress that destroys OEM components. The aluminum finish can be polished, chromed, or powder coated to match your build, or left raw for a functional underhood look.
Track and dyno-ready design. The tank accepts dry ice or ice packing, dropping coolant temps rapidly before a dyno pull or drag pass. Lower coolant temperatures translate directly into denser intake charge and more consistent horsepower runs, making this a practical tool for anyone chasing quicker elapsed times.
Fuel cell style filler cap. A billet-style locking filler cap replaces the factory overflow cap, providing a secure, leak-resistant seal rated for the pressure demands of a forced-induction cooling system.
Product Benefits
- Aluminum Construction: Resists heat-related failure that plagues factory plastic tanks on supercharged applications.
- Battery Location Fitment: Mounts cleanly in the stock battery tray for a tidy, purpose-built installation.
- Ice Packing Capability: Accepts dry ice or ice for pre-run coolant chilling on the track or dyno.
- Fuel Cell Filler Cap: Secure, pressure-rated cap included for leak-free operation.
- Finish Flexible: Polish, chrome, powder coat, or leave raw to suit your underhood aesthetic.
- Increased Cooling Capacity: Higher volume reservoir supports the elevated thermal load of supercharged 4.6L engines.
Note: Fits 1996-2004 Mustang 4.6L supercharged applications. Battery relocation is required; use Moroso Sealed Battery Box No. 74051 (sold separately) or similar relocation kit.
