1988-1993 Chevy C1500/K1500/Suburban Radiator for LS and LT Engine Swaps
When converting a 1988-1993 C1500, K1500 or Suburban to an LS or LT engine with automatic transmission coolant management is essential. The 1988-1993 LS Radiator 34 inch Core Width for Automatic Transmission drops into factory brackets on GMT400 chassis, aligns with stock hose angles and retains transmission cooler connections. Precision TIG welded aluminum tanks and a 34 inch core maintain stable operating temperatures under heavy loads or sustained cruising in hot weather. Matching original mounting points and flow paths this radiator avoids custom fitting hassles and delivers consistent thermal performance for LS and LT swaps in Chevy C/K trucks and Suburbans.
Maximized Cooling Efficiency with 34 Inch Aluminum Core
The expansive 34 inch core dramatically increases the surface area where coolant passes through tightly spaced fins, enabling rapid heat exchange even under demanding towing conditions or high ambient temperatures. By drawing heat away from the engine block across a broad section, this design prevents hotspots that can lead to thermal stress and performance loss. Aluminum's superior conductivity ensures that heat is distributed evenly over the entire core, maintaining a stable operating range when climbing grades or cruising for extended periods. Consistent temperature control not only preserves engine power but also reduces the risk of coolant boiling and component wear.
Robust TIG Welded Aluminum Structure
Precision gas tungsten arc welding fuses high quality aluminum tanks and core into a single sealed unit that resists vibration, pressure fluctuations and repeated thermal cycles. This welding method creates a uniform bond without the need for gaskets or mechanical fasteners that can loosen or leak over time, ensuring coolant remains contained in extreme conditions. The corrosion resistant properties of premium aluminum further guard against rust and pitting, extending service life and reducing maintenance concerns. Built to meet strict manufacturing tolerances in the U.S.A., this radiator assembly delivers reliable performance mile after mile.
Seamless Factory Mount Compatibility for LS and LT Engines
Engineered specifically for 1988 through 1993 C1500, K1500 and Suburban models, this radiator integrates directly into stock mounting locations without trimming or adapter brackets. It retains original hose angles and preserves automatic transmission cooler connections, resulting in a straightforward installation that minimizes labor time and potential leak points. By matching the factory flow paths and pressure requirements, the design ensures proper coolant circulation through both engine and transmission from the very first startup. Technicians and enthusiasts benefit from a plug and play solution that eliminates custom fitting hassles and maintains system integrity.
Tailored Finish Options for Durability and Style
Owners can choose between a natural bare aluminum surface or a protective black epoxy coating to suit either a classic restoration or a modern custom engine bay. The untreated aluminum forms a natural oxide barrier that inhibits mild corrosion while preserving maximum thermal transfer efficiency. Alternatively, the epoxy layer adds a resilient barrier against road debris, moisture and chemical exposure without hindering heat rejection. Both options maintain an open fin pattern for unobstructed airflow and let builders match or contrast the radiator finish with their vehicle's overall aesthetic.
