SPELAB Engine Coolant Radiator for Nissan Altima & Maxima 2007–2019 — 2.5L/3.5L Auto, Direct-Fit Reinforced Tubes

This SPELAB radiator is a direct-fit replacement built to restore proper cooling performance for compatible Nissan Altima and Maxima vehicles. Designed with reinforced tubes and thicker walls, it addresses wear-prone areas found on older units and provides an upgraded thermal path to maintain engine temperatures under everyday driving and heavier loads. Before ordering, double-check your vehicle year, engine size, and transmission type to ensure fitment—this unit is not compatible with Altima 2007–2011 L4 2.5L Hybrid models.

Will this radiator fit my specific Nissan model and engine?

It replaces several common part numbers, making it a practical swap for many repair scenarios. Hybrid Altima L4 vehicles from early model years are excluded.

How does SPELAB improve durability and heat management over an old radiator?

This radiator uses thicker tube walls and higher-grade materials to resist corrosion, vibration, and fatigue that commonly shorten radiator life. SPELAB subjects each unit to endurance and aging tests to help ensure consistent thermal performance and longer service intervals under variable weather and driving conditions.

• Increased tube wall thickness for improved structural strength
• High-quality materials that resist corrosion and leaks
• Aging and endurance testing to simulate real-world conditions
• Core dimensions tuned for correct fit and flow: 26.5" × 16.0" × 0.6"
