2001 Excursion with no mods and 100,500 miles. Noticed my anti freeze about 3/4" low. So I checked my engine oil and it looks to have a green tent. It also seems to have a small lifter tick from the engine. Oil does not look milky but looks normal except for a slight green tent. Did not notice any oil in the tank of the radiator. Any good tricks for determining if it is a head gasket or an oil cooler problem. Or any quick ways of testing for anti freeze that I can do my self since it is Friday and I don’t think I can get an oil sample done this weekend.
