The 1967 to 1987 GM Truck Radiator 18.5" Tall (Auto Trans) with Fans solves cooling demands of LS and LT swaps in Chevy and GMC C K Series trucks, Blazer, and Suburban models. Its 18.5 inch aluminum core features built in transmission cooler ports and standard cooling passages to match factory bracket locations, inlet and outlet fittings, and hood clearance. Dual high output electric fans engage on temperature rise to maintain fluid flow and heat rejection during towing or traffic. Made in the United States with a choice of bare aluminum or black epoxy coating, it preserves original service points and simplifies installation. Standard architecture ensures direct fit and reliable operation.
Overview
The 1967 to 1987 GM truck radiator stands at 18.5 inch tall and is designed specifically for models equipped with an automatic transmission. Featuring dual performance fans pre installed the design delivers consistent airflow under heavy load. Constructed from premium aluminum and assembled in the USA the radiator offers a balance of weight control and heat rejection. This application focuses on model year trucks where the height and mounting points align with original equipment specifications. The automatic transmission version includes dedicated ports for fluid cooler lines. That ensures optimal temperature management for both engine coolant and transmission fluid within the same compact package.
Design and Construction
The core structure employs precision welded tubes and fins that optimize surface area and flow. Aluminum construction reduces overall mass while resisting corrosion from coolant additives. The thickness of the core section and the 18.5 inch dimension allow increased coolant volume compared to standard replacement units. Dual fans are matched to the core profile providing ample cubic feet per minute to maintain operating temperature in stop and go traffic or towing duty. The fan shroud is formed for close clearance to the radiator face. Fasteners and fittings use stainless steel hardware to guard against rust. Manufactured in the USA each unit undergoes testing for leak and pressure resistance before leaving the facility.
Integration and Compatibility
This radiator is engineered for LS and LT engine swaps when installed with MuscleRods mounting brackets. That partnership ensures correct engine placement and proper drive line angles to preserve performance and avoid undue stress on accessories. MuscleRods mounts align the radiator with frame rails to allow clearance for stock style control arms and steering linkage. The automatic transmission cooler ports fit standard fluid lines for GM applications eliminating the need for custom adapters. Fitment to 1967 through 1987 GM truck frames is assured by the precise bracket locations. Users gain a direct replacement that integrates seamlessly into a retro fit or restoration project without alteration to the chassis or front cross member.
