I have a 1998 S70 GLT with 130k miles. It is "blowing out" some antifreeze from the weep hole at the bottom of the intercooler assembly.

Does that mean that the turbo has developed a crack or seal leak in the internal cooling?

Thanks.

Are you sure it is antifreeze? It is common, and desirable, for it to drip out water and often that water is oil contaminated and it can look like antifreeze. That said it shouldn't be more than drops and certainly not a stream.

If the turbo cracked I would be looking for oil in the coolant rather than coolant through the intercooler. The oil pressure is much higher than the coolant pressure and a crack in the turbo housing would mix the oil and coolant with the oil winning the pressure war. It would need to be a very strange crack for coolant to get into the compressor side of the turbo. but not mix with the oil.
