aFe BladeRunner Street Series Tube & Fin Aluminum Radiator 01-05 GM Diesel Trucks 6.6L V8

Application-specific coolant service

The aFe 46-52031 coolant component is for the specified GM 2500/3500 6.6L turbo-diesel; 2001-2005 in the exact manual versus current listing 2003-2005 application. TIG-welded aluminum radiator with a 2-3/4-inch four-row tube-and-fin core, stated by the manufacturer to be twenty-five percent larger than factory, fabricated 1/8-inch aluminum end tanks, billet inlet/outlet and brushed finish. Published core comparisons are manufacturer claims, not independent measurements.

Key Features

• TIG-welded aluminum radiator with a 2-3/4-inch four-row tube-and-fin core, stated by the manufacturer to be twenty-five percent larger than factory, fabricated 1/8-inch aluminum end tanks, billet inlet/outlet and brushed finish. Published core comparisons are manufacturer claims, not independent measurements.
• Match the exact cooling component, engine, chassis and supplied hardware.
• Use the actual vehicle coolant specification, refill and air-bleeding procedure.
• The current exact manufacturer listing states that this radiator does not require a CARB EO number.

Fitment

46-52031: The complete twenty-page exact manual explicitly covers 2001-2005 GM 2500/3500 6.6L turbo-diesel, while the current primary listing headline starts at 2003. Original 2001-2002 coverage is therefore retained with this primary-source conflict disclosed, not silently deleted or certified against the narrower current listing. The fixed exact-part named retailer table restores Silverado 3500 LT 2001-2005 and Sierra 3500 SL 2001-2002. Existing Base pseudo-labels become model-level coverage subject to the diesel engine condition. Silverado 3500 WT remains 2004 only because no exact named proof fills its gap. No gasoline or other engine approval is inferred.

Specifications

What's Included

• One radiator, one drain valve and two transmission-cooler fittings. Original mounting screws/brackets, rubber mounting grommets, hoses, fan/shroud assembly and correct radiator cap are reused. No filter, coupler, hose kit, new fan, coolant or additional cap is established in the exact bill of materials despite generic website Filter Included/Coupler Included fields.
• Secure the radiator to the intercooler with original mounting screws and brackets. Refit the lower shroud, both original radiator hoses, overflow hose and cooler-line connections. Reinstall fan, upper shroud, A/C-hose clip, computer/cover, both charge tubes with clearance, air-box brackets, intake and sensor. No new computer or charge-pipe kit is included.

Lubricate supplied cooler-fitting O-rings with grease before installation. Apply appropriate thread sealant to the supplied drain valve. Transfer upper original rubber mounting grommets and verify lower grommets sit correctly on the intercooler. Lubricate cooler-line ends with transmission fluid and restore their retaining clips/covers.

Begin with the engine and pressurized cooling system fully cooled before opening the cap or draining. Use the actual vehicle coolant specification and complete factory refill/air-bleeding procedure, then set the expansion/overflow tank to its specified max line. Test-drive, cool completely and recheck levels. Inspect all connections again after 50-100 miles; no universal coolant volume is given.

The exact manual provides no numerical mounting, fitting, drain-valve or hose-clamp torque. Use the actual factory and boxed-hardware instructions; no values from intercooler pipes, transmission pans or a different radiator are borrowed.

Remove the intake/resonator where fitted, unplug the intake sensor, and remove air-box mounting/support brackets and both charge tubes. Move the computer and plastic cover aside, release the A/C-hose clip and upper shroud, then remove fan/clutch assembly, original hoses and transmission-cooler connections. Release lower mounting brackets and upper radiator screws; lift the radiator with help.

Secure the radiator to the intercooler with original mounting screws and brackets. Refit the lower shroud, both original radiator hoses, overflow hose and cooler-line connections. Reinstall fan, upper shroud, A/C-hose clip, computer/cover, both charge tubes with clearance, air-box brackets, intake and sensor. No new computer or charge-pipe kit is included. With the vehicle cool and level, set the brake, disconnect both negative battery cables and drain safely. Remove the documented intake supports, both charge tubes, computer/shroud and fan assembly; disconnect hoses and cooler lines and lift the old radiator with help. Install supplied cooler fittings with lubricated O-rings and the sealed drain valve; transfer upper grommets and verify lower grommet locations. Seat the new radiator with assistance and reuse original mounts/brackets. Restore shrouds/fan, hoses, cooler-line clips, computer, intake brackets, charge tubes and sensor, checking tube clearance before tightening. Reconnect batteries, refill and bleed correctly, test-drive, check transmission fluid, cool completely and recheck coolant. Recheck all connections after 50-100 miles.
