LS and LT Radiator for 1967-1987 C/K Series Chevy GMC Trucks Blazer Suburban
If you're installing an LS or LT powerplant in a 1967 through 1987 C K series truck or Blazer Suburban with manual transmission, this 18.5 inch tall radiator with fans ensures coolant hoses and mounts align without trimming or adapters. Its aluminum core and dual electric fans deliver consistent airflow at idle and under towing loads, maintaining optimum engine temperature during extended runs. Each inlet outlet and bracket matches factory dimensions on C10 C15 K10 K15 Blazer and Suburban frames so installation time is shortened and potential leak points are minimized. Installation is further simplified by pre wired fan connectors and factory mounting points that eliminate the need for extra relays and brackets.
Drop In Radiator Fitment for 1967 to 1987 C K Series Trucks
This 18.5 inch tall radiator is engineered to match the exact core height and bracket spacing used on 1967 to 1987 C10, C15, K10, K15, Blazer, and Suburban frames. By mirroring factory layout, coolant hoses and transmission cooler lines slip into place with no trimming or adapter kits needed. Installers save time and avoid guesswork, while the precise alignment reduces stress on fittings to help prevent leaks. This drop in solution preserves the original engine bay appearance for restorations and performance builds alike, ensuring the cooling system fits seamlessly with manual transmission setups.
Dual Electric Fans for Steady Airflow during Idle and Tow Conditions
Equipped with two electric fans, this assembly maintains constant airflow even when the vehicle is at a stop or under heavy load at low speed. Each fan activates based on coolant temperature, ensuring uniform air delivery across the full aluminum core to eliminate hot spots and resist heat soak. Pre wired connectors remove the need for extra relays or switches, streamlining the electrical installation process. The result is a cooling circuit that dynamically adapts to driving demands, maintaining optimum engine temperature in traffic or under towing stress.
High Conductivity Aluminum Core for Rapid Heat Rejection
The entire core is constructed from high quality aluminum, providing superior thermal conductivity compared to traditional copper brass units. An optimized tube and fin design maximizes coolant volume and surface area, accelerating heat transfer during sustained highway runs or towing duty. Aluminum's natural resistance to corrosion reduces maintenance requirements and extends service life without adding weight. By rejecting heat more quickly, this radiator maintains stable engine temperatures under varied driving conditions, delivering performance and reliability for daily drivers and weekend haul rigs.
Coating Options Offering Protection and Style
Customers can choose between a classic bare aluminum finish or a black epoxy coating applied to the core and tank surfaces. The bare metal option delivers minimal weight while showcasing the natural gleam of aluminum, ideal for those seeking an authentic engine bay look. The epoxy coating adds a protective barrier that resists chips and oxidation, preserving appearance over time and simplifying upkeep. Both finishes are applied in a precise factory process to ensure even coverage and lasting durability in demanding environments.
