Description

The HSP Factory Replacement Coolant Tank (027-HSP) is engineered as a premium upgrade for 2001-2007 Chevrolet and GMC Duramax trucks equipped with LB7, LLY, and LBZ engines. Unlike the original plastic tanks that degrade and fail from heat, pressure, and age, this tank is precision CNC-cut from aluminum, hand-formed, and welded for superior durability and longevity.

MIA's Description

The HSP Factory Replacement Coolant Tank is a direct-fit upgrade designed for 2001-2007 Chevrolet and GMC Duramax trucks with LB7, LLY, or LBZ engines. This aluminum tank is a robust alternative to the OEM plastic version, which can become prone to cracking, leaking, and failure over time due to heat and pressure.
