HSP Factory Replacement Coolant Tank for 2001-2007 Chevrolet / GMC Duramax LB7 / LLY / LBZ
The 027-HSP, or HSP Factory Replacement Coolant Tank, is designed for 2001-2007 Chevrolet and GMC Duramax trucks. Its a perfect upgrade that delivers both function and style while retaining OEM fitment.
Why You Need an HSP Factory Replacement Coolant Tank
As your truck ages, OEM plastic tanks become prone to cracking, leaking, and general failure. HSPs aluminum replacement resolves those issues and offers a cleaner, more durable solution that also looks great in any engine bay.
What Makes the HSP Tank Different?
The factory tank is plastic, discolors over time, and cant handle long-term heat or pressure. HSP starts with precision CNC-cut aluminum, forms and welds it by hand, and finishes with your choice of powder coating. Designed with all factory provisions and fittings, it even reuses the OEM low coolant sensor to avoid triggering any check engine lights. This tank is a true drop-in replacement built to last.
