    Default 99 V70XC - Coolant leak near turbo

    Hi,
    I have a coolant leak somewhere in the back of the engine near the turbo. Can anyone educate me if there are any coolant hoses, etc. in that area that can be checked. I can't see anything back there.
    Most of the coolant drained from the overflow tank the other day and was leaking out toward the back of the engine. The oil looks fine. After the engine was cool I refilled and idled the engine until it came up to full temperature and the thermostat opened. I could not see any leak at that time. I also turned on the heat to see if it might be one of the heater hoses but they were OK. At idle there didn't appear to be any leak. I revved the engine up to 3-4K or so and sure enough a leak began from the back of the engine.
    Any info would be appreciated.
    Thanks,
    Gary

    Hi,
    It turned out that it was actually one of the heater hoses near where it attaches to the engine block. The coolant was running down the back of the transmission and out under the turbo.

    Yea. You should replace both heater hoses and inspect your heater core while your at it. Also inspect the entire cooling system before you put new coolant back in.
