I have a '96 Camry, 4-door, 2.2 cylinder. I've discovered the anti-freeze overflow tank boils like a tea kettle after a drive to work (10 mi.), to mom's house, etc. The existing overflow tank had a hole in it which I've replaced. It continues to boil and spills out via the black tubing on top.
I fill up the overflow tank daily with about 8 oz. water.
Has anyone else had this problem? What was your fix?

sounds to me like theres a clog in the system...does the vehicle overheat?
most common problem with this type of stuff i think has to do with a poor radiator cap and/or a stuck/sticky thermostat.
moreover if ur just filling with water all the time...how much coolant is actually still in the system...water has a low boiling point compared to coolant...u need to have a 50/50 mix of water/coolant or at most 75/35 mix of coolant/water.

Just curious to know how long you've been filling up with water?

As stated before its more than likely a stuck thermostat or bad radiator cap. My suggestion would be to replace your thermostat and buy a new radiator cap. There both fairly cheap around 30$ in all. Giver er take. The work is fairly simple for anyone who knows there way around cars. While your at it you should flush your cooling system out. Its fairly easy as well. Drain all the coolant out of the bottom hose or drain plug on the radiator. Close it and fill with water let it run for 10mins once youve replaced the thermostat. Then drain the water and fill your coolant to a 50/50 mix of water and coolant. That depends on the climate you live in also. Once you filled it up and all is normal check for leaks and make sure its full. Be sure you use the proper type of coolant which in your case is EG ....The green stuff

If your description means that after you drive about 10 minutes then park and turn off the engine - then the coolant boils over - it is more likely the rad cap and/or possibly because you have been replacing lost coolant with plain water. Diluting anti-freeze lowers the boiling point. When the engine is turned off it heats up before it cools down and could raise the coolant temp to boiling point. If the rad cap is not able to hold the added pressure then it will blow off, lowering the pressure and further lowering the boiling point. If your engine temp is normal while driving I would not replace the thermostat. Check your coolant concentration and for about $5 replace the rad cap.

Thanks everyone. Here are some responses to your questions:
o I fill it up daily.
o The car does NOT overheat.
o I live in Los Angeles.
o I have NOT been diluting the mixture.
Tomorrow I will buy a new radiator cap and fill it up with 50/50 mixture and monitor the situation. I will try this first. Thanks again everyone.
