I changed the oil and filter on my 05 RX330 today and I was cleaning the engine compartment. I noticed that the metal portion of the transmission cooler hoses closest to the bottom of the radiator have a coating on them which almost looks like corrosion. The pan under the front end of the car protects these hoses and the bottom of the radiator but they are still suseptable to get road salt and snow in there. Has anyone else noticed this? The film on the metal looks like the type of coating that you see on an aluminum chair when it is left outside.
