Volvo 850 Turbo, 1994, 112,000, 2.3L; The water pump on the car went out while driving on the freeway, after replacing the water pump I began to refill the cooling system with coolant. Coolant ran out of the back of the engine. I traced the leak to the turbo charger, when I pulled it off coolant ran out of the chamber on the exhast side, there was no evidence of coolant in the exhaust system. Why would I have coolant inside the turbocharger? I tried to donate but the link did not work.
