Built to Handle Heat, Pressure, and Real Work

Not all coolant tanks are created equal. This is OEM-grade polypropylene construction is designed to survive extreme temperatures, vibration, and daily abuse without cracking out.

✔ High-temp polypropylene (PP) construction

✔ Handles engine heat, pressure cycles, and vibration

✔ Resists cracking in cold weather conditions

✔ Chemical resistant to modern coolants + additives

✔ Translucent body for quick level checks

✔ Direct replacement for 575.10123A style reservoirs

Most aftermarket tanks cut corners - thin walls, recycled plastic, poor molding. They might look the same on the shelf, but they don’t last in real conditions.

• Constant heat cycling
• Coolant pressure fluctuations
• Engine vibration
• Harsh winter conditions

The result: A reservoir that holds up longer, reduces failures, and keeps trucks working. 

Translation: fewer cracks, fewer leaks, fewer comebacks.
