The damage from road salt comes from underneath. I don't know that you can really do much about it. I suppose if you could regularly drive over an array of fresh water nozzles that were pointing up, that could help. Does that one have an aluminum radiator? If so, keep it rinsed often. My Father-in-law, who lived in North Myrtle Beach, had a minivan that was only a few years old when it started overheating for no apparent reason. It turned out most of the aluminum radiator fins had corroded off from the salt air.
If you live in a salty place, buy cheap, disposable cars.
The drive thru "full service" car washes have undercarriage wash ,, nozzles that point up ..
Two of my trucks after eight to ten years start to develop problems mostly brake lines rotting out ,, but the salt gets every where .. If you plow which I do, carrying the plow creates a different wind pattern and the inside of the engine compartment becomes covered with salt and also needs to washed regularly,, if you plow the heat shields on the exhaust off the motor don't last long and ate first to go ..
