Perrin Coolant Overflow Tank is a replacement coolant overflow reservoir designed to upgrade and clean up your engine bay by swapping out the stock plastic tank with a sturdier, CNC-machined aluminum unit from Perrin Performance. Its a universal-style tank that works with many OEM cooling systems and adds extra space around intercooler piping and performance hardware.
- Precision-crafted, CNC-machined aluminum construction for improved durability compared to OEM plastic.
- Approximately 36 cubic inch capacity, suitable for most coolant overflow applications.
- Integrated lid lets you quickly check and top off coolant without removing hoses.
- Includes universal hardware: silicone hose (~55), multiple mounting brackets, and installation hardware.
- Universal design fits many vehicles that use a standard overflow reservoir and works especially well with performance kits lacking a coolant tank.
This tank replaces the weak, often brittle factory plastic reservoir with a tougher aluminum unit that both functions reliably and gives the engine bay a cleaner, more purposeful look.
