I would either advise that you refill the cooling system with dex-cool or compatible antifreeze, or flush the complete system and refill with clean 50/50 green antifreeze. I would also recommend that you contact your local auto part store to see if they rent fan clutch removal tool set. See the fan clutch threads onto the end of the water pump on this model. Here is what you will be getting into. Feel free to contact me with any questions! Good luck!
