1997Volvo S90Thermostat Gasket

Post by maj357 »

When flushing out the radiator and replacing the thermostat, must the fiber housing gasket be replaced along with the O Ring seal for the thermostat? When looking at ordering a gasket, there are pictures of a round fiber gasket with only one inlet and pictures of a rectangular fiber gasket with two inlets?
Can anyone explain what I need for this job?
