1 Answers
Solutions for a thermostat that always fails to open: 1. Eliminate airlocks; 2. Clear the vent hole; 3. Repair or replace the wax element. Reasons why a thermostat may fail to open: 1. Presence of airlocks preventing hot coolant from contacting the wax element; 2. Vent hole stuck or blocked; 3. Malfunctioning wax element; 4. Insufficiently high water temperature; 5. Frozen radiator. A thermostat is an automatic temperature-regulating device that operates by expanding or contracting to open or close the flow of coolant. It automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, altering the coolant's circulation range to regulate the cooling system's heat dissipation capacity.
