Review on MotoRad 523 160 Thermostat With Seal by Juan Gomez

March 31, 2020 I installed this thermostat on February 20, 2020 on my Silverado LT 5.3 2009 along with the new Gates water pump (no other mods), for service my engine and transmission at a safe temperature. I almost never hear my fan turn on when my AC is on. OEM thermostat, 195.UPDATE! 4 months later September 19, 2020, from 1st post. I've driven the Silverado extensively, with the A/C on and in extremely hot southern conditions with no issues so far. Winter is coming, I will update again.
