Windchill LS Swap Radiator Kit With Dual Fans
Best for: LS swap builds requiring maximum cooling capacity with a universal fit. This 33×19-inch aluminum radiator uses a three-row core and dual 12-inch fans to move heat efficiently, making it suitable for high-performance G-Body swaps.
Why selected: It combines a robust dual-fan setup with a built-in steam port and standard LS hose fittings, simplifying installation and improving heat rejection in demanding applications.
Caution: Universal fit means you should verify hose routing and mounting clearances for your specific chassis before purchasing.
3 Row Cooling Radiator Fan Shroud Set
Best for: G-Body owners upgrading cooling with a compact, high-flow 3-row core. This set is designed to fit Camaro, Monte Carlo, Cutlass, Grand Prix, and El Camino radiators from 1978-1987, providing better airflow with a racing-oriented core.
Why selected: The 3-row design paired with a dedicated fan shroud improves cooling efficiency in hot climates or during spirited driving.
Limitation: It’s optimized for specific G-Body and compatible models; verify core dimensions against your radiator core size before ordering.
CUBAUTO 3 Row Core Radiator With Shroud
Best for: Budget-conscious builders seeking a complete 3-row aluminum radiator with shroud and relay, suitable for El Camino and other 70-87 GM tank-style radiators.
Why selected: All-aluminum construction with TIG-welded joints offers lightweight durability and improved cooling versus stock radiators in LS swap scenarios.
Limitation: Requires careful measurement of overall dimensions and inlet/outlet sizes to ensure compatibility with your engine bay and hose kit.
LS Upper & Lower Radiator Hose Kit
Best for: G-Body LS swap projects that need reliable hose routing with LS engine integration. This hose kit is designed to pair with GM LS swaps in the G-Body family.
Why selected: High-quality upper and lower hose kit helps ensure a clean, leak-free connection between the radiator and LS engine, reducing fitment headaches.
Caution: Hose kits must be matched to radiator inlet/outlet sizes; confirm compatibility with your chosen radiator core and fittings.
Buying Guide: Key Considerations For G Body LS Swap Radiators
What core configuration should I choose?
- Three-row cores offer higher cooling capacity, which is useful in hot climates or high-performance builds. Double-pass crossflow designs can improve heat transfer efficiency by circulating coolant twice through the core.
- Four-core options may provide extra cooling, but check fitment and overall vehicle weight impact.
What material matters?
- All-aluminum radiators are common for LS swaps due to lightweight construction and strong heat transfer. TIG-welded end tanks reduce the risk of leaks compared with some welded joints.
- Poly/aluminum hybrids exist, but aluminum generally offers better cooling efficiency for LS swaps in G-Body cars.
How important is fitment?
- Measure core height, width, and tank thickness to ensure the radiator fits the engine bay and aligns with the fan shroud and transmission cooler if included.
- Check inlet/outlet sizes to match your hoses and adapters. Some products offer LS-spec hose fittings standard, which simplifies installation.
What about ancillary components?
- Fan configuration (single, dual, or triple) affects cooling capacity and electrical load. A shroud improves airflow efficiency by guiding air through the core.
- Transmission cooler integration can be important for automatic transmissions in performance builds; confirm whether a cooler is included or needs to be added separately.
Which option should I choose?
- For maximum cooling in high-performance LS swaps, consider the Windchill LS Kit with dual fans and a three-row core.
- For a balance of performance and budget, the Cubauto 3 Row Core Radiator with Shroud provides solid cooling with a complete mounting package.
- For tight spaces or classic restoration projects, the 3 Row Cooling Radiator Fan Shroud Set targets compatibility with common GM G-Body radiators.
Frequently Asked Questions
- What is the advantage of a three-row radiator for an LS swap? Three-row radiators typically offer greater cooling capacity, which helps prevent overheating in high-load or hot-weather conditions common in LS swaps.
- Do I need a specific hose kit for a G-Body LS swap? A hose kit that matches your radiator’s inlet/outlet sizes and LS plumbing is recommended. Look for LS-spec hose fittings when possible to simplify installation.
- Is an aluminum radiator better than a copper/brass radiator for LS swaps? Yes. Aluminum radiators are lighter and provide efficient heat transfer, which is beneficial for performance-focused swaps in G-Body cars.
- Will a dual-fan setup fit in all G-Body engine bays? Not always. Confirm available space behind the radiator support, shroud dimensions, and fan depth before purchasing.
- Should I add a transmission cooler with my radiator? If your build uses an automatic transmission, a built-in transmission cooler or an external cooler helps manage transmission fluid temperatures, improving reliability.
- What is crossflow versus traditional flow in radiators? Crossflow radiators route coolant from one end to the other, allowing larger cores and better heat transfer, which is advantageous for LS swaps in hot climates.
