car radiator for Chevy Malibu LT 2.4L engine

1. Core Fitment & Compatibility

• Core Dimensions: 26.75″ × 14.5″ × 0.88″ (approximately 68 cm × 36.8 cm × 2.2 cm)
• Core Type: Single-row, cross-flow aluminum
• Tanks: Durable plastic with an integrated transmission cooler
• Flow Path: Cross-flow design ensures consistent cooling performance
• These specifications allow a drop-in replacement—no cutting or modification needed for the Malibu LT.

2. OEM-Equivalents & Aftermarket Options

• Standard direct-fit radiators in aluminum with plastic tanks match OEM performance and mounting points. They include a built-in transmission cooler and cost between $75–110—ideal for everyday use.
• Performance upgrades feature dual-row or thicker multi-row aluminum cores. These offer 30–40% improved heat dissipation, making them excellent for heavy use, towing, or hotter climates. Check for clearance before installation.

3. Symptoms of Radiator Failure

Watch for these signs:

• Engine overheating or visible steam under the hood
• Coolant leaks beneath the vehicle—check hoses, tanks, and core
• Discolored or rusty coolant indicating corrosion
• Persistent air pockets or bubbling in the overflow reservoir even after proper coolant fill and bleed

These can signal blockage, corrosion, or leaking, and often point to radiator issues.

4. Installation Guide

1. Drain coolant via the petcock with the engine cold.
2. Remove fan shroud, upper/lower hoses, transmission cooler lines, and mounting bolts.
3. Extract the old radiator and clean the surrounding area.
4. Install the new radiator—secure in mounts and reconnect hoses and cooler lines.
5. Refill with fresh 50/50 coolant mix and bleed air by running the engine with the heater on until stable temperature and no air bubbles appear.
6. Test-drive to check for leaks and optimal temperature stability.

5. Maintenance Tips

• Flush the cooling system every 2–3 years to remove rust and debris.
• Inspect hoses, clamps, and thermostat during radiator replacement to ensure system integrity.
• Replace the radiator cap if worn—it's vital for maintaining the correct system pressure.
• Use proper coolant type (typically factory-specified DEX-COOL) to prevent corrosion and prolong life.

6. Summary

• Choose a direct-fit aluminum radiator with plastic tanks and built-in transmission cooler for reliable, OEM-level performance.
• Consider a thicker, dual-row aluminum upgrade if your driving conditions include towing, heavy loads, or hot weather.
• Ensure proper core size and mounting compatibility to avoid installation issues.
• Regular maintenance—coolant flushes, hose checks, and pressure bleeding—will help extend the radiator’s service life.
