    ok new swap same motor Si to Si.

    For some reason my radiator fan does not turn on . Maybe because car did not run long enough, maybe.

    On the back of the block its the 2 pins that stick out next to each other above the oil filter right?

    How long does the motor have to run for the fan to turn on?

    It's based on temperature.. just hold your engine around 2-3k rpm until it either kicks the fans on or your temp starts rising above normal. Another option would be to swap the fan switch from your old engine onto the new engine since it looks like that one was working properly.

    Bro, does anybody know what size is that bolt???????

    I don't have a wrench or deep socket to get it.

    Honda dealer told me its 24mm , well 24mm can't even get it around the sensor let alone the bolt.
