Don’t leave it in there! the oil will deteriorate your rubber hoses and maybe the water pump seal. What you need is a good cooling system flush. It involves taking out the thermostat and running a flush solvent through the engine, then replacing it with fresh coolant. To have that done at your convenience, contact YourMechanic. They will send a technician to your home or office to flush your cooling system right there on the spot.
