1991 Honda Civic Front Wheel Drive Automatic 142, 00 miles

My daughters car is losing coolant but I cant tell where it is going. I dont see any wet spot on the car or driveway, none on dip stick, no white smoke, I cant figure out where it is going! Any ideas? Thanks, Jeff

You should have a mechanic to pressure test the radiator, if the pressure test is good no signs of coolant leak, you may have a bad head gasket that coolant could leak into the combustion chambers. You could also do a compression test to see if there is any low compression in the cylinders. Normal compression should be about 170psi
