Keep us posted on what u do to correct the problem. Based on your description it sounds like the rad is plugged up.

There are various radiator treatments on the market that is supposed to 'boil out' crud from the radiator. I havn't used any since the late 1980's. I usually used the DuPont or other well recognized name braand.

NO!!!. i am not talking about a radiator flush or treatment that is simply a pour in and drive type treatment but rather a PROCESS that involves draining the system, dumping in the treatment, running engine for maybe 5 minutess, draining out the treatment solutution, adding a nuetralizer and then restoring the original coolant to the radiator and engine. HOWEVER i mite add that results were routinely marginal or only solved the problem for maybe a year.

Easy enuf and cheap enuf to try. U mite have better reults than i have.
