Blue Bird Radiator - Blue Bird 01769470, Northern Radiator 239278, Spectra Premium 20015104, Reach Cooling 42-10439

If you are sourcing a replacement radiator for a Blue Bird TC1000 or TC2000 bus, the Reach Cooling 42-10439 is the aftermarket direct replacement built to meet or exceed original equipment specifications. This unit crosses to Blue Bird 01769470, Northern Radiator 239278, Active Radiator Supply Company 3100-01ST, Spectra Premium 20015104, 1-800-Radiator 2400696, and Serck FLA001002, making it straightforward to confirm you have the right part before it ships. Fitment spans Blue Bird SHL TC2000, TC1000, and TC2000 models from 1994 through 2000 across multiple engine displacements. The aluminum core and plastic tank construction mirrors the original design, while engineering upgrades like B-type tubes with central reinforcement reduce the probability of tube failure under pressure, and deep extrusion headers strengthen the tube-to-header joint to resist the effects of vibration and thermal cycling. Thermal expansion cuts allow the core to breathe through normal heat cycles, extending service life, and folded fin edges improve stability and heat disbursement. Longer header tabs add pressure resistance at the tank-to-header seam. For fleet buyers and mechanics keeping Blue Bird buses on the road, the Reach Cooling 42-10439 delivers a correct, dependable fit that eliminates the guesswork.
