over heating 94 Toyota Camry?
i changed to thermostat and also i flushed the radiator with a garden hose and she still ova heats, if i turn the heat on it is manageable when the needle hits the red but not on the expressway.there is always spillage and heat and bubbling in the ova flow tank. on the inside of the car sometimes there is gurgling coming from below the middle of the dash board im guessing the heater core. heat only blows out of the heater when i hit the gas or the car is in motion. there is no leakage of anti freeze inside of the car. is it the radiator or the heater core? thanks guys!!
mr. pilsner man,..dont have any white smoke and the loss of coolant is from the over flow tank and the peculating sounds is coming from the over flow tank as well. no water in the oil and also on the inside with the dash it sounds like a rush of water here and there going through a pipe, it did that sound for a long time even when i didn't have that over heating problem. you still think it could possibly be the head gasket? p.s and thanks for answering the emails and also the info on the flannel shirts lol!!

You have a bad head gasket.
They can pressure test the cooling system for that.
ADDED: It can be pressure tested, or the coolant can be tested for hydrocarbons. Here's how it works with some head gasket problems. Very small leak from water jacket to cylinder. Intake stroke, valve is open so not much vacuum on the leak, still will suck in a tiny bit of coolant. Compression stroke, 150PSI pushing into small leak into the water jacket, sending pressure to the radiator and out past the cap to the overflow tank. Exhaust stroke, valve is open so not much pressure.
Another thing you could do is pull the spark plugs. If there is any coolant being sucked into the cylinder, the top of the piston will usually have all the carbon gone off the top, and be nice and clean.

have you put any radiator coolant into the engine? water alone will evaporate and you will probably fry your engine if you keep running a hose through it. check your owner's manual and see the proper procedure (sometimes a half/half mix of distilled water and coolant works too).
