    Help!!!!! Overheating prob.

    I own a 02 Subaru WRX. I recently installed an alluminum radiator that has a cap on top. The problem is that a hose coming from the other tank (near turbo) is free and decided to put a T connector on and run all hoses to radiator cap..... I was driving it and in about 5 min. the temp needle began to rise slowly all the way to the top. I got a CEL that came on which was P0117....Engine coolant tem sensor circuit low input. Can someone help??? fyi.... the radiator fan fuse was blown, put new one on and blew as well. Passenger side fan working properly.

    You have two separate issues.

    The overflow from the radiator cap, if there is one, and from the turbo coolant reservoir should be tee'd after both caps so that they join to one line that goes to the overflow reservoir. Also, the system needs to be burped, as you may have air pockets. Burp the system.

    As for the fuse, did you reconnect the harness correctly?
