• Fitment: CU2346 for 2000–2006 Sentra 1.8L
• OEM reference compatibility: 214106M100, 214604Z000, 214606M100, 214606M110
• Inlet/outlet diameters: 1-1/8" each for hose compatibility
• Complete assembly includes transmission oil cooler section

How does the Torchbeam design improve cooling and durability?

This radiator uses a high-density aluminum core and multi-layer cooling fins to increase heat transfer area and speed heat rejection. A thicker, well-formed core and solid end-tank connections reduce the chance of leaks and improve long-term durability under daily driving conditions.

• Core dimensions: 27-1/16" width × 14-1/8" height × 3/4" thickness
• Aluminum core with multi-layer fins for efficient heat dissipation
• Factory-placed inlet/outlet for correct hose alignment
• Reinforced mounting points and corner foam in packaging to prevent deformation

What’s included and what should I expect during installation?

The Torchbeam package ships as a complete radiator assembly ready to swap in place of the factory unit. Because it’s built to OEM reference numbers and dimensions, you can expect a straightforward replacement process using existing brackets and hoses. Always inspect hoses, clamps and fan shroud for wear when replacing the radiator.

• Included: 1x Torchbeam complete radiator (CU2346) with transmission oil cooler
• Pre-mounted fixtures and corner foam to protect the core during transit
• Same inlet/outlet sizes to reuse original hoses and clamps
• Recommend replacing coolant and checking fan, thermostat, and hoses during install

How does the transmission oil cooler integration benefit my vehicle?

Having the transmission oil cooler integrated into the radiator consolidates cooling components into one assembly, saving space and simplifying plumbing. It helps keep transmission fluid temperatures within a safer range during normal driving, towing, or stop-and-go traffic, which can extend transmission component life.

• Integrated cooler reduces extra plumbing and potential leak points
• Dedicated cooling circuit for transmission fluid inside the radiator body
• Matches OEM cooler locations for direct hose connection
• Helps maintain transmission fluid temperature under load

Who this is for: This Torchbeam radiator suits DIY mechanics, independent shops and Sentra owners who need a reliable, cost-effective replacement that mirrors OEM fit and function. It’s ideal for vehicles with leaking cores, collapsed cooling fins, or failed internal passages where restoring factory cooling capacity and maintaining transmission temperature control is the priority. If you want a direct-fit aluminum radiator with integrated transmission oil cooling and straightforward installation for 2000–2006 Nissan Sentra 1.8L models, this Torchbeam unit is built to meet those needs.
