Hi I have a 98 S70 and it is leaking coolant from under the engine on the drivers side about 18in from the wheel. I have a friend who said it may be from the turbo. It seems to be dripping off the transmission but I can see nothing from the top of the car. The resevour was full last night and is empty today. My friend is coming to look at the car tonight but I would like to get the parts before the dealer closes. Can anyone tell me what hoses go in and out of the turbo that carry coolant? Thank you
-D

 

I'm not aware of any coolant in the Turbo. It's oil cooled.

 

Maybe one of the heater hoses?
Jim the turbos also have coolant lines running to them. They are oil and coolant cooled.

 

I replaced the 6" long L shaped hose from the turbo but I am now having some serious overheating problems. It wont over heat when in the driveway but about ten minutes out on the road the needle jumps to the red and i have to pull over to let it cool off. There isn't a noticable leak out the bottom but the tank keeps sucking down coolant. Any Ideas?

 

You might want to try a complete flush of the entire system, make sure all coolant is good, and no air pockets. You can easily burn that turbo up so be careful. I'm assuming up and low radiator hoses are good, thermostat is good, and all the basics like that. You know like water pump changed at 70k along with the timing belt???? I'm also assuming that the hose you replaced did stop the leaking??
