What manufacturing and quality checks does Gates perform?

Gates subjects each 42005 pump to strict quality controls that catch assembly or material issues before a unit ships. Castings are tested to ensure they don’t leak, bearings and seals are function-tested, and the fully assembled pump receives a final leakage inspection. These steps reduce early-life failures common with lower-grade aftermarket parts.

• Leakage testing on both casting and assembled pump
• 100% functional test of bearings and seals for rotational and sealing integrity
• Premium materials chosen to withstand heat, coolant chemistry and wear
