GM 6.2L & 6.5L Non-Turbo Diesel Fuel Injector | Alliant Power DT650001R Remanufactured
This is the Alliant Power DT650001R, a mechanical fuel injector from the Alliant Power DTech line, remanufactured by Alliant Power. It is for GM 6.2L and 6.5L diesel V8 engines without a turbo. It replaces GM 10233972 and 12458121, and the new Bosch injector for the same engines is 0432217275. These engines take eight, and a refundable core applies.
GM used several different injectors on the 6.2L and 6.5L over the years. The 6.5L turbo diesel takes a different injector, GM 10233973, and some earlier 6.2L engines take GM 14059057. Hard starting, white smoke on a cold start, a rough idle or a miss that stays with one cylinder are the usual reasons to replace a set. Before you order, read the number stamped on your old injector and have the model year ready.
