Volvo 940/960 » Overflow Reservoir & Caps

When replacing a faulty radiator keep in mind the stress put on the other heating/cooling components. The overflow bottle caps have a pressure rating and it is important to match the correct cap with the radiator. We do not recommend using the higher pressure (gray, green or white 150 KPa) caps as the higher pressures can cause your radiator and hoses to fail prematurely.
