So after hearing horror stories of people ruining there alternators, in the mud and water I decided to come up with something to help protect it from being splashed... So this is what I made:

I started with some heat shield I picked up at the junkyard

Then me and a friend cut it down and started trimming it up

I mounted it using two holes pre-drilled holes in the sub-frame

And this is what I ended up with

Before:

After

And it's kept my alternator clean since!!!

Thx man, defiantly worth it, just need to find a way to stop my fan from spraying water everywhere, I sucked some in last time and painted the front bit of my engine bay, my alternator was clean all day till I did that, still runs quiet but it's no longer shiny

Another member brought up an interesting point in another thread that i hadn't considered...

Can be easily solved though - the shield only needs a connection to hold it up, therefore i would recommend enlarging the hole (in the guard) for the engine side mount so the bolt can freely move horizontally with the engine, and use a large fender washer so the guard still supported by the bolt vertically. I do it all the time with building structure expansion joints where i need a bearing connection.

Thats a great idea dude. Keep that metal fatigue to a minimum.

Actually had already removed the bolt off the engines threaded bolt because it unscrewed the bolt (I feel dumb, I forgot) so my painted version is only on using the two frame bolts, but I should drill out the engine whole bigger cause mine still catching on the threads

Looks good, but I suggest removing the bolts from the frame rail and finding a different way to mount it. The motor torques around and will eventually fatigue the plate or bolts.


Never mind. Was already covered

This is a great idea! My alternator had to sit out and dry for a few days the last time I went mudding because it got soaked
