I just got a new 2024 Ford Explorer as a work car last week. Broke the shield my 3rd day driving it after hitting a small bump. Probably will never be replaced.
I use an automatic car wash often - it has piping from underneath that surely has more jet impingement that just a drive in the rainWhen I arrived after a long trip in my Volvo I found the belly pan dragging on the road. I threw it in the trunk. It was made of really heavy stuff and was hardly damaged. I put it back on at the first opportunity.
Manufacturers don't design and build expensive parts for no reason.
That’s what I’m thinking = like BMW did …The next time I change the filter on my Nissan I’m going to cut an access door in the plastic.
Heck, some pans are plastic these days …My local 10 min oil change shop did it for me by failing to secure it years ago. Lost on the road somewhere. I didn't address the issue. This was on a VW Passat, the car my daughter used for college years ago. Sure enough, on one trip home I noticed oil pooling under the car. The oil pan was cracked. Never cracked an oil pan before or since so from my experience DON'T RISK IT!
Shops and oil service chains started charging extra if the vehicle had an under shield. Another reason I will never darken their doors again.
This.They can be there for a number of reasons for them. Slight MPG improvement as mentioned. Some are designed to help pull air through the engine bay - creating a suction in the back to pull the air out vs pushing it up. Keeping water from splashing up into the bay as much. You will never really know.
Personally I would keep it, but I am certain many people do not and motor on without issues.
That's what I did years ago to access the trans fluid drain in my 08 Accord. Seems to be ok.The next time I change the filter on my Nissan I’m going to cut an access door in the plastic.
