    Please help me identify what it is leaking.
    Volvo 2009 whit ISX
    Leaking something what is attached inside the frame on passenger side. Four hoses connected, two connected to the pipes from the rear of the engine block and two to cooling system. Right now is dark couldn't see anything good what is leaking. Hope it's a rubber.
    Can I bypass this thing??

    Any coolant leak you can visibly locate is a good thing. On an ISX you are going to eventually start losing about a gallon every 1000 or so miles with no visible leak. That will be your EGR valve and it's not a quick or cheap job.

    Can be a cold weep. Only leaks after everything cools down so you never see it

    Sounds like what Ben is saying, power steering cooler.

    Mine is located on drivers side but mine has a Volvo motor.

    Thank you all guys for help. Yes it was a power steering heater. One of the rubber hose to connect heater core and pipe from the rear of the engine.
    Bad thing it's happen in rural south Illinois area at night. Next day was driving really slow to the nearest Walmart. Got big enough container to drain coolant and 3/4 inch diameter rubber hose from O"Raily auto parts.
    To drain coolant from radiator just use 1/2" garden hose, drive phillips srewdriver inside along the hose in a couple inches from the end. Then slide hose over the radiator drain nipple and push valve with screwdriver. Don't forget to put other end of the hose into container.
    Real problem was to fill system with coolant after repair. Total coolant loss was about 5 gallons and no final charge red coolant available around. I put some final charge but pink in color. Have no idea about can it be mixed or no

    The rules of the thump for the coolant mix is 10 % if you go above this the long life coolant will loss his (function) and act like std coolant. (That's what manufacturer told us about that?)

    There is a little mistake by Snailexpress he type the wrong word, , ,i think
    The correct sentence is power steering heat exchanger (cooler) mean (oil to water exchanger).
