rear radiator?. If so can you can bet it needs cleaning. You can spray it good with simple green and spray water from a hose. I had to do my rear radiator several times to get it cleaner. Not sure I ever got it really clean. Mine was a cat and a cat service center pressure sprayed it. Really have to know what you are doing so it does not bend the fins on the coils with that pressure so usually not recommended that an owner take this approach.
