Well, my water pump was leaking, and all those hoses were getting old and nasty. So I changed it all! Including the thermostat and heater control valve. Just a heads up: I learned what to remove along the way. For a quick tip, just remove almost everything on the passenger side of the engine to access what you need for this job (air box, battery box, AC unit, and various tensioner brackets and pulleys). Watch the whole video to see what exactly I did.
