Occasionally the old rivets holding the louvers on my engine hatch are coming loose. I've experimented with some ways to fix these and made a short video of what seems to work on my Champion Diesel. I use either self drilling 10-16 x 3/4" pan head philips screws or if the hole is blown out on the louver I found that standard license plate screws fit perfectly.
Note: Zip ties are a must in your RV supply kit and work great for holding the louvers on temporarily. In this case mine weren't long enough so I threaded 2 together to get the length to go around the louver and support bar.
