I live in sunny florida and drive my s70 t-5 pretty hard. only engine mods are K&N and Supersprint. the car has been analy maintained. i have noticed that it has been spending its coolant. no leaks that i can detect, i have checked every hose possible and even had it taken into the volvo dealer to have the coolant hoses replaced. it still is eating coolant though. it was topped up about a month and a half ago and it already is halfway between the min/max mark. does anyone know what is going on here? my A/C works fine and there is no sweet coolant smell, my evaporator and a/c system is in fine working condition , i even had the tracer die put in it and we checked for leaks 3 times and couldnt find them. i heard something about a leak within the engine block. though the car performs extremely well, could there be a coolant leak into the oil or engine which would cause it to be evaporated. i notice in the morning that alot of white mist comes out of the tailpipe while the car warms up...maybe thats related?
