MR481216 Mitsubishi CAP,RADIATOR, Price: 13.84$, Weight: 0.04kg

Radiator Pressure Cap for Mitsubishi Cooling System ❄️

This cap seals and pressurizes the cooling system, letting your engine run at the right temperature and preventing boil-over. It keeps coolant inside under controlled pressure, raises the boiling point, and returns coolant from the overflow bottle as the engine cools. Choose this cap to restore proper pressure, stop leaks at the filler neck, and protect the water pump, hoses, and radiator.

How it works

A spring-loaded main valve holds a set pressure. When pressure rises, excess coolant flows to the reservoir. After shutdown, a vacuum valve opens to pull coolant back, keeping the system full and air-free. High-temp rubber seals ensure a tight fit on the neck.

When the cap fails ⚠️

Expect overheating, steam, hard upper hoses, coolant smell, stains near the neck, weak heater, or hoses collapsing after cooldown. You may see overflow bottle filling but not returning. Long-term use can warp heads or damage the radiator.

Fitment Tips

Open only on a cold engine. Clean the neck, check for nicks, and seat the cap squarely until it stops. Replace if the gasket is cracked or spring feels weak.
