Cleaning the Fan Shroud
I decided to clean up the fan shroud next. I decided to take it apart (mostly because I was curious what it looked like inside), but also because I thought it would be easier to clean.
There is a set of flaps inside this shroud that can either direct airflow to, or away from, the cylinders and heads. This is used to help the engine warm up on cold days. The flaps are connected to a spring loaded linkage that is controlled by a bi-metallic bellows (that expands and contracts from heat). I don't have that bellows and don't drive the car in the cold, so I leave the flaps "open" all of the time.
Anyhow, after removing the two screws that hold the linkage bar in place, the flaps can be separated from the shroud.
And, after undoing the perimeter bolts of the shroud, it can be opened up:
After a thorough cleaning with a degreaser and elbow grease, the shrouds were cleaned up well.
So I decided to treat them to a coat of silver paint! That should give it a nice "extra touch" once it's all back together.
