Hey guys just picked up a 90 camry v6. Drove it home about 30miles and it started overheating about halfway there. Pulled over let it cool and checked the coolant level. There was no coolant in the radiator. Been a couple days

now and about every 2 days i have to add about 1/5 quart of coolant. The AC fan is wired to a switch and was on all the time. Now that I drive with it off it hardly uses coolant but it still does. At first I thought it would be the HG but

there is no white smoke. What could cause it to use up coolant when my ac fan is running? Small leak somewhere? Hose or heater core? Have to lift up the car to check it out.
