Brown liquid

Blinker fluid pump is going out , it looks like rusty water when that happens

 

Usually just condensation in the emissions box getting blown out after you first start the truck for the day.

 

or just simple rain water , has happened since flex pipe has been used

 

Cover your stacks when it rains. Don't cover your stacks with the engine running...and yes I had to tell a guy that one time. He was chasing a coffee can all over the yard.

 

Turns out that gave him an idea and he became very wealthy. Was his last name Sanborn?

 

We used to have contests to see who could shoot their stack cover the farthest. When there were still metal coffee cans you could get some serious altitude and distance with the small Folgers can.
SSSShhhhhh...don't tell the boss.

 

Just rain water with rust. It’ll burn out nbd

 

these used to work well , it was like a symphony at a truckstop with these clanking.
