Keen Parts now offers an exact reproduction of both styles of coolant crossover pipes used on LT1 engines from 1992 to 1997. This pipe mounts on the back of the engine at the top and has been known to go bad over time due to corrosion. They were used in all Camaro, Firebird, Corvette, and full size GM vehicles that utilized the LT1 engine. There is a short version of this pipe, which was used in early LT1’s , and a long version of this pipe which was used in later engines.
These pipes are a direct fit replacement for the original pipes, and include the correct style drilled bolts, as well as the the correct washers to seal the bolts to the pipe. The long pipe (250046) is a replacement for GM # 12556260, and the short pipe (250047) replaces GM # 10108636. Please call Keen Parts for additional information and pricing at 800-757-5336.
