Nissan Consumer Affairs Oil Cooler Response

Thus, at a local mechanic no one will give you a hard time nor document that you have an oil cooler. If something big happened, you could just pull the oil cooler off and then drop the car off at Nissan for warranty work. Clearly not an ideal situation though.
