coolant overfilled?
thermostat not opening allowing pressure to build-up?

Please test the radiator cap with a pressure tester. Also, look for a cracked head or bad head gasket.

Would antifreeze coming out of the overflow cause the temperature gauge not to work?
no you need to replace temperature sinding unit
Where do you add antifreeze in a 1999 Mazda 626?
I'm guessing that it has a closed radiator, so one would use the overflow basin to add liquids. Otherwise one would use the radiator cap..
Why would your radiator suck up antifreeze from the over flow?
If there is no leak visible so you can see antifreeze under the parked car, you probably have a head gasket going bad. You may have some signs of steam in your exhaust, or at least a sweet smell coming from the exhaust. You should have a compression test done on your engine. That is exactly what the overflow reservoir is for. When the engine is hot, excess coolant goes into the overflow tank, as the engine cools,it draws coolant back into the radiator.
What is the signs of a broken heater core?
Leak. What kind of liquid should be coming out? Antifreeze? Oil? And would it make the overflow for the raditor liquid bubble?
Why would antifreeze leak from the radiator?
There may be a hole in the radiator?
What would cause a 2003 Buick Century's heater to blow cold air when idleing but will blow warm air when moving?
Probably need to add antifreeze. Check the Radiator not the overflow tank. If you are low on antifreeze it will not circulate through the heater core.
Why would a just cranked 1986 Chevrolet Celebrity leak steaming antifreeze from the overflow radiator tub after idling for 10 minutes?
You most likely have a blown head gasket or cracked head
I Put dot 3 brake fluid in antifreeze how bad is it?
If you put the brake fluid in the overflow reservoir just empty the reservoir and pour in a 50/50 mix of antifreeze and distilled water. If however you put it in the radiator itself, I would recommend you drain the radiator and refill. Brake fluid is corrosive and may damage the water pump seal.
What would cause sludge in the radiator and overflow on a 1994 Camaro 6 cylinder?
If you have the pink Dexcool antifreeze in it then that is the reason. You can go on the web and there are several class action lawsuits against General Motors concerning the issue.
Why is antifreeze blowing out from the radiator cap of a Nissan Titan?
If it's just blowing out when you start it you probably have a cracked head or blown head gasket. If there is oil in the radiator there is a change you have oil coming in from the transmission cooler. But there would have to be a lot of oil to make antifreeze come out the radiator cam. Since you did not mention oil I would suspect the head gasket. If you got it hot I would lean toward a cracked head.
You have antifreeze leaking only when car is running It is dripping down underneath the passenger side next to trasmission It is pure coolant You changed thermostat?
I would check the hoses leading into your radiator, and also the overflow for antifreeze. If that is not the problem, it could be your heater core. Your heater core might be leaking, you might have a hose leaking
What is that bubbling noise under hood in Nissan Pathfinder?
If it is coming from the radiator or the hoses this would mean your antifreeze is boiling in the lines. I would recommend first changing the thermostat and bleeding the air from the rad lines.
