dirty COWL ???

I've used a water hose to flush all that out. The drains dump the debrie down the forward door jamb area to behind the fenders so those drains beneath the fender will need flushing also. I've you dont have a rocker molding extending onto the fender you can remove the 2 bolts each side and pull out on the fender a little. Watch for shim washers locationed behind those bolts.
