Description
Overview
The AWE Tuning ColdFrontâ„¢ Engine Coolant Reservoir is a purpose-built upgrade for the Audi 3.0 AWD Sport Utility platform, engineered to bring consistent, reliable performance to supercharged and modified vehicles. Designed in-house by AWE, this coolant reservoir tank is CNC machined from 6061 Billet Aluminum and plumbs directly into the heat exchanger coolant system to increase supercharger coolant capacity. If you’ve been searching for a premium automotive coolant reservoir that does more than simply hold fluid, the ColdFrontâ„¢ Reservoir is built to actively improve your cooling system.
By expanding total coolant capacity, this coolant tank helps lower coolant temperatures, which in turn supports lower air intake temperatures — a meaningful gain for owners chasing maximum power and thermal security. It’s the coolant reservoir for your car when temperature management directly impacts how hard and how consistently your engine can perform.
Key Benefits
Unlike a basic coolant overflow tank, the ColdFront™ Reservoir incorporates a true flow-through design. Coolant is actively routed through the unit, and that flow works to reduce coolant temperature as it passes through — turning this antifreeze reservoir into a functional part of your cooling strategy rather than just a passive reservoir tank. Whether you view it as a coolant expansion tank, a radiator coolant overflow tank, or an upgraded antifreeze reservoir tank, the goal is the same: cooler, more stable temperatures.
- CNC machined from 6061 Billet Aluminum for strength and durability
- True flow-through design that actively reduces coolant temperature
- Increases supercharger coolant capacity for lower coolant and air intake temps
- Anodized aluminum cap laser etched with the AWE logo for easy level checks
- Hardware included and no tune required for installation
- No CEL Guarantee and AWE Fit Guarantee for confident, correct fitment
Options & Flexibility
The ColdFront™ Reservoir is designed to work either in combination with other members of the AWE ColdFront™ product line or with your factory heat exchanger — so you can integrate it into an existing cooling upgrade or run it as a standalone improvement over the stock coolant reservoir. The anodized cap makes monitoring your coolant level effortless, and the billet construction gives your engine bay a finished, purposeful look.
Fitment & Notes
This engine coolant reservoir is built specifically for the Audi 3.0 AWD Sport Utility application and is backed by AWE’s Fit Guarantee. Installation requires no tune, and all necessary hardware is included. Please note this product carries a Voluntary CARB Restricted label. For owners weighing coolant reservoir replacement cost against a genuine performance upgrade, the ColdFrontâ„¢ Reservoir delivers a durable, functional antifreeze reservoir that improves your cooling system rather than simply matching factory spec.
