Hi does anyone know the correct pressure for a radiator cap for this model car. I have a new cap which is .9 but seems to let go far to quickly sending coolant into the overflow bottle. SHould the cap pressure be higher say 1.0 or 1.1????????

The coolant is being pumped out far to quickly leaving minimal collant in the radiator....

If coolant is flowing into overflow to the point it is overflowing, you have bigger problems than the cap.

Check the compression on all cylinders, looking for a head gasket leak. If OK, then do a pressure test on cooling system.

.9 is correct cap.
