Thermostatic Radiator Cap, Universal Thermostatic Radiator Cap Waterproof Water Tank Cover with Temperature Gauge (Big Head 1.1bar)

The cover of the thermostatic radiator is made of silicone rubber, which has good sealing performance and can effectively prevent water leakage from the radiator. As the water temperature drops, a vacuum will form inside and the lid will open to suck water from the auxiliary radiator into the water tank to keep the water level balanced. The thermostatic radiator cover is designed to adjust the pressure of the radiator and maintain the water level in the water tank. The thermostatic radiator cap can improve the pressure and cooling performance of the radiator, and at the same time modify the appearance of the engine compartment. Constant temperature radiator cap, once the discharge pressure exceeds 0.9 kg, the radiator cap spring opens and the coolant flows to the auxiliary radiator for storage.
