The fan run constantly on my 625, shows a code 1long 3 short, Dealer said its the temp sensor so I replaced it with no change, Also when I removed the sensor no antifreeze came out at all even though the radiator is full, I checked the water pump and its fine, Even pulled the thermostat and re bled the system. fan still comes on and still the same code. It runs fine and does not over heat however if I use t for 30+ minuets and shut it off it floods out sometimes it will start but I have to hold it wide open and clear it out, Sometimes it wont start at all . but if I wait 5 mins it starts right up, not sure if this is related to the code. Thanks for any advice I can get!
