Technical notes

The 212-8177 is the jacket water (fresh water) circulating pump for Caterpillar 3500-series diesel engines, mounting to the front of the block and driving coolant through the cylinder jackets, oil cooler and heat exchanger circuit. Distributors confirm fitment across the 3512/3512B/3512C and 3516/3516B/3516C diesel range, plus 3508B, and equipment such as the 994 loader, 777D/785/789C/793B trucks. Suppliers list 416-0610 as a related number and 10R-1669/10R-1670 as Caterpillar reman alternatives. On 3512B marine ratings this pump handles the fresh-water (jacket) side of the cooling system feeding the heat exchanger, distinct from the separate auxiliary/seawater pump. Note Caterpillar also builds spark-ignited G3500 gas variants; this diesel pump is listed for the diesel 3512B, not gas-only service.

Frequently asked questions

Does Caterpillar part 212-8177 fit the 3512B diesel engine?
Yes. Independent diesel distributors (Diesel Pro Power and Propel Parts) both list 212-8177 as fitting the 3512B along with 3512, 3512C, 3516, 3516B and 3508B diesel engines.
Is 212-8177 the same as a seawater (auxiliary) pump?
No. The 212-8177 is the jacket water / fresh water circulating pump that moves coolant through the engine and heat exchanger circuit; the raw/seawater side of a marine cooling system uses a separate auxiliary pump.
What are common alternate or replacement numbers for 212-8177?
Distributors cross-reference it to 416-0610, and Caterpillar remanufactured equivalents are listed as 10R-1669 and 10R-1670. Always confirm against your engine serial number.
