Performed swamp cooler inspection. Found what appears to be original swamp cooler showing age. Water pads don’t fully cover the doors. Some air gaps. Found unit leaking water thru float constantly. When float seals it sprays out of nut connection from water line. tightened connector water leak stopped Motor looks ok. Belt and pulley a little loose. Belt is starting to crack, But holding. And pulley appears to missing proper set screw. System is working just showing age. Went thru swamp cooler to find any and all issues that might come up.
