Review on ๐ŸŒก๏ธ Engine Coolant Thermostat Water Inlet Assembly: GM Genuine Parts - 15-11057 by Darnell Nahabet

Revainrating 5 out of 5

Smooth cylinder block coolant intake with modern replaceable 180 degree injector. Thermostat

Pretty simple cylinder block coolant inlet bolt replacement with modern replacement 180 degrees. Thermostat for my 2000 Chevy Silverado 1500, 5.3L V-8 LS at 100,000 miles. The internal flow path seems smoother than the old nozzle and 180 degree thermostat that came with it and replaced separately.

Pros
  • Durable finish
Cons
  • So-so
