It looks like my 1993 Plus 8 has a pressure cap on both the radiator and the expansion tank. Not sure what pressure the relief valve is set to (there is a number 13 stamped to the cap so maybe 13 psi). From the advice of this group it sounds like I should change the radiator cap to just a standard shut cap and allow the pressure relief to occur on the expansion tank side. Is there any downside in keeping the current configuration?
