The system was overfilled and purged the excess coolant.
no you need to replace temperature sinding unit
Head gasket or cracked head. Mo
The antifreeze level in the overflow tank can drop due to several reasons, including coolant leaks in the system, evaporation over time, or a malfunctioning radiator cap that allows coolant to escape. Additionally, if the engine is overheating, it can cause the coolant to expand and push some out of the overflow. Regularly checking and maintaining the coolant level is essential to prevent engine overheating and damage.
If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown. If it is transmission fluid in your antifreeze, then the radiator is leaking from the transmission cooler ----- although usually that would cause antifreeze to be in your transmission fluid.
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.
First thing would be to check if you have enough and correct water/Antifreeze mix in the overflow tank.
Check Antifreeze level..make sure there are no leaks under the vehicle.
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.
Yes, an overflow of antifreeze or engine coolant can cause smoke and a burning smell if it spills onto hot engine components. When coolant leaks onto the engine, it can vaporize and produce smoke. Additionally, the coolant can burn, creating a sweet, acrid odor. It's important to address any coolant overflow promptly to prevent engine damage and ensure safe operation.
Antifreez, make sure your mixture is right
Sounds like the rubber line on the bottom of reservoir is leaking or tank is cracked CHECK IT OUT.
Leak. What kind of liquid should be coming out? Antifreeze? Oil? And would it make the overflow for the raditor liquid bubble?
