Bigger Core, Lower Temps, More Confidence for the 2011-2014 Chrysler 300

The aFe BladeRunner Street Series heavy-duty radiator 46-51003 replaces the factory heavy-duty radiator with a larger-core, higher-capacity unit engineered to maintain safe coolant temperatures under the sustained loads that overwhelm the OEM cooler. Built with an expanded core design compared to the factory unit, this is a direct bolt-on replacement that uses factory mounting points, hoses, and connections without any cutting or custom fabrication. For diesel trucks, towing rigs, and high-output builds running harder than the factory heavy-duty radiator was designed for, the 46-51003 is a critical upgrade.

Key Features

  • Expanded core design for superior thermal dissipation
  • Direct bolt-on using factory mounting brackets and hose connections
  • Higher coolant capacity than OEM for improved thermal buffering
  • Compatible with factory coolant hoses and fittings
  • Designed for high-load applications: towing, diesel trucks, and performance builds
  • Backed by aFe Power BladeRunner limited manufacturer warranty

Frequently Asked Questions

Will this radiator work with my existing overflow reservoir?

Yes. The 46-51003 is designed to interface with the factory coolant overflow reservoir using OEM-compatible hose fittings. No reservoir modification or replacement is required in most applications.

Should I flush the factory coolant before installation?

Yes. Whenever replacing a radiator or cooler, flush the entire cooling system with clean distilled water before installing the new unit. This ensures no old degraded coolant or debris is introduced into the fresh system.

What coolant type should I use with this radiator?

Use the coolant type and concentration specified in your owner's manual. For diesel and high-output applications, a fully formulated extended-life coolant with a supplemental coolant additive (SCA) package is recommended. Do not mix different coolant chemistries.

Does this radiator fit with my aftermarket fan clutch or electric fan upgrade?

The 46-51003 is designed around OEM fan placement and clearances. For electric fan upgrades, confirm radiator thickness and fan positioning against your specific fan kit before ordering.

Will this help with coolant temperature issues while towing?

Yes. The expanded core capacity of the 46-51003 is specifically designed to address coolant temperature excursions during sustained towing or high-load operation that the factory radiator cannot adequately manage.

Is this compatible with my transmission cooler lines?

Many OEM radiators have integrated transmission cooler ports. If the 46-51003 replicates these ports, your factory trans cooler lines will connect directly. Verify this with the product listing or contact us before ordering if you have an integrated cooler.

What is the warranty on this radiator?

aFe Power provides a limited manufacturer warranty on BladeRunner radiators covering defects in materials and workmanship. Warranty does not cover damage from improper installation, overheating events, or using incompatible coolant chemistry. Contact us for full warranty documentation.

How long does installation typically take?

Most experienced installers complete a radiator swap in two to four hours. Budget additional time if the vehicle has significant rust on hose connections or a complex fan shroud mounting system.

Installation Overview

  1. Allow the engine to cool completely and safely lift the vehicle for access to the front fascia
  2. Drain the cooling system using the factory drain petcock or lower radiator hose
  3. Remove the upper and lower radiator hoses and any transmission cooler lines
  4. Disconnect the fan shroud and carefully remove it before lifting the radiator out
  5. Remove the factory mounting bolts and lift the radiator straight up and out
  6. Compare the new 46-51003 to the old unit for mounting hole alignment before installation
  7. Lower the new radiator into position and secure all mounting hardware
  8. Reinstall the fan shroud, reconnect all hoses, and transfer any transmission cooler line fittings
  9. Refill with fresh coolant at the correct concentration, start the engine, and bleed the system of air
  10. Check for leaks at all connections after reaching operating temperature

Coolant Reservoirs

Coolant Reservoirs

Coolant reservoirs, also called expansion tanks or overflow bottles, maintain a pressurized coolant supply that the radiator draws from as the cooling system cools down after engine-off. A cracked or leaking reservoir causes coolant loss and eventual overheating, while an upgraded billet or aluminum tank improves appearance and durability in performance engine bays.Popular UpgradesAluminum and billet coolant expansion tanks for LS and LT engine swaps and popular domestic performance vehicles are the most popular upgrades, providing a clean look and superior durability compared to factory plastic bottles that crack from heat cycling. Universal inline overflow tanks made from polished aluminum or anodized billet are popular on custom engine bays where the stock location has been eliminated. Direct-fit OEM-style replacement tanks restore coolant system function on high-mileage vehicles where the factory tank has cracked or the cap seat has deteriorated.How do I know if my coolant reser...
