TA Performance offers some of the best replacement water pumps for the Buick engines. These water pumps are NEW, not re-built and incorporate bearings on the shaft vice bushings as most re-built pumps use.

Note: When Transplanting a 400-430-455 engine into a `64-`72 A-Body or `78-`87 G-Body use water pump p/n TA 1537B for best fit. When using a donor 455 from a `71-`76 Fullsize car with a long nose pump it will be necessary to change the water pump pulley to the pulley used on `67-`70 fullsize and `67-`72 GS 400/455 cars originally equipped with short nose pumps. TA usually has good used original pulleys or our billet aluminum pulley p/n TA 2029T is also correct for this application. Please call for additional information.
