Key Features of the Remanufacturing Process:

1. Deep Cleaning: The engine is fully disassembled, cleaned using hot tanking (for cast iron) or thermal cleaning (for aluminum).
2. Inspection: Comprehensive inspection including Magnaflux testing to detect cracks and fissures, followed by a visual check of all parts.
3. Machining and New Parts: Key components like deck surfaces are CNC machined. New parts are installed, such as bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, galley plugs, and timing components. Timing chain-driven engines receive a new chain and tensioners, while timing-belt engines are fitted with a new belt and tensioner. Water pumps are also replaced if timing-driven.
4. SIM Testing: After reassembly, each engine undergoes SIM testing to ensure the cooling and oil systems are fully pressurized, and the crank spins at high RPMs to verify compression and overall build quality.

Warranty and Protection:

• Each engine is backed by up to 7 years and 1 million miles of warranty, with the option to upgrade to Pure Care™ no-fault protection, offering the best warranty coverage in the industry.

This remanufactured engine is a reliable and durable choice, with a meticulous process to ensure it meets or exceeds OEM standards, making it ideal for long-term performance.
