$292.60

Product Highlights:

Proper heat management from the cooling system is crucial on modified engines when you want trouble-free and reliable performance. The factory Duramax water pump is known to slip under load and can serious problems and serious repair bills on modified high-horsepower applications. This updated design is a drop-in replacement for the factory water pump and uses precision TIG welds to secure both the impeller and pump gear to the shaft. If your 2001-2005 Duramax powered truck is running a tuner, a bigger turbo, or bigger injectors, or if it’s just time for routine maintenance, get peace of mind with the Sinister Diesel Welded Duramax Water Pump.
