My '03 Toyota Camry is overheating and I can't use the air-conditioning anymore though I know I shouldn't use it until this problem is solved. It seems to be losing water and I don't see any leaks. It looks like the water in the radiator is evaporating. Moreover, I hear this gurgling sound like pipes being flushed when I start my engine after having parked for a few minutes.
Do you
have the same problem?

If coolant is depleting, there must be a leak somewhere and a pressure test should be able to locate the source.

Where is the gurglng noise coming from, inside the car?

Thanks for a quick response. Okay, a pressure test. Will try that. I can hear the gurgling noise from inside the car when I start it up but it appears to be from inside the engine compartment. Sounds like pipes flushing.

When air is trapped in cooling system due to leakages, the gurgling noise can occur at the heater core.

Thank You KHLow2008. I found out that there was a hairline crack in the engine jacket inside which the water appears to circulate evidenced on the outside by residual coloring of the coolant mixture, and I used a sealant compound which appears to have held although the temperature seems to still be a little on the high side. How do I bleed the air outta the cooling system?

When engine is cold, remove the radiator cap and check the coolant level. If level is low, then air is present. Top up and run engine with radiator cap off and heater turned to maximum. Top up colant whenever necessary. Turn off engine after 5 minutes. Close radiator cap and run engine until operating temperature and ensure radiator fans comes on. Stop engine and allow to cool before rechecking coolant level. Top up if necessary.
If temperature is still higher than normal, ensure the cooling fans are working correctly and repair if necessary. If fansa are working correctly, have the thermostat checked/replaced if necessary.
