The Seal Ring, thermal switch (104 529) maintains stable coolant flow throughout the engine. Replacing it with a Porza-quality pipe restores reliable cooling performance and long-term engine protection.
A seal ring for a thermal switch is a sealing component used to ensure a leak-free connection where the switch is installed. Its function is to prevent fluid or air leakage while maintaining proper pressure and accurate temperature sensing.
Key specifications include inner and outer diameter, thickness, material (such as rubber or heat-resistant elastomer), temperature resistance, and compatibility with the thermal switch and system. It must withstand heat, pressure, and fluid exposure.
Replacement is necessary when the seal is worn, hardened, cracked, or leaking. It is also recommended to replace it whenever the thermal switch is removed or serviced.
