radiator losing fluid 92 camry

[siklein]

My 1992 camry, every 3 days or so I have to ad radiator fluid (about 1/2 galon or so), however car does not overheat, but temp gauge goes to red zone I changed the hoses, and the radiator and the cap, but problem has not been solved. I do not see any leak under the car either? Any suggestions?
Thanks

I would check your engine oil and make sure the fuild is not showing up in your oil pan. Next I would recommend you have a local service station but a pressure test on your radiator and see if they can spot the leak. If not then ask them to add some dye to the radiartor fluid and drive your car for a few days. The dye will seep out and show up with use of a black light.

One more thing check your floor boards and see if the carpet is moist. You may have a heater core leak?

Also check the water pump.
