    Default 1JZ water pump outlet

    Does anyone know where the small outlet at the back of the water pump, facing diagonally down towards the chassis rail on a soarer goes to or comes from?
    thanks

    pretty sure it goes to the turbo water lines...
    the 2 bolt one goes right round the back of the block
    the big one goes to the radiator
    the others go to turbo water lines...
    the one on the front behind the pulley doesnt go to anything but will start leaking when the pump is fucked

    so you mean it links up with the 2 that feed the turbos from the top cast section that runs into the top of the radiator?

    no... it should run to the front turbo its like a u shaped hose IIRC
    the 2 on the upper housing go to the 2 hardlines along the top... see my members ride thread and you will see a picture of the top 2...

    there is an outlet on the hard metal line that runs around the back of the block that goes to the rear turbo...

    on my single setup this one at the rear has been deleted (cut and welded up)
    the 2 on the upper have been cut and welded up and a new one has been placed facing downwards (allows more clearance for the inlet pipe)
    i have the one you have questioned feeding my turbo water line and the other side runs to the new downwards facing nipple on the upper neck...
