I m new in this forum
I have a S6 2007 5.2 V10, sins a year ago i considered a coolant leak from the right side of the engine.
i have checked everything from radiator , hoses and changed the coolant reservoire and cap aswel
last weekend i finished the carbon clean and i couldnt see any leak from the coolant pipe behaind the engine
now is still leaking and i think it is the O ring for the coolant pipe .
my question is it possible to change them with engine in car or it is engine drop job
