After a little deeper investigation it does appear that the factory radiator on my 2003 GT has failed. Most likely cause: cracked plastic end tank. I pour water into the reservoir up top and the water just empties on the passenger side of the radiator down towards the bottom.
The car is still pretty much in stock form, no major engine modifications to speak of, just exhaust. It sees daily duties for the most part (though I do now have a second vehicle).
Should I stick to an OEM-style radiator with the plastic end tanks that could crack again as a replacement, or would it be worth upgrading to an all-aluminum radiator for at least twice the price? If all-aluminum, is there a preferred brand?
