I never see coolant in the oil, I've had it tested. and it shows OK. no coolant.
It's been doing it since new. no bad effects -- yet.
I don't think it's the way it should be but ?
Mystery coolant loss in a car is usually due to a leaking seal in the water pump. If yours has been doing it since new, perhaps it's either a defective pump OR a poor hose connection allowing it to drip out after the system gets up to pressure. A hose clamp loose or something. I'd check for 'telltale' type streaks of coolant somewhere under the engine around the rad or following the heater hoses to the dash comfort radiator...but outside the firewall otherwise you'd smell it inside.
That's what we thought, so we had all hoses changed to the new Teflon and kevlar type, no change. no leaks.
