if you run your engine without antifreeze your car will overheat and ruin the engine.
You replace the radiator
If the entire system (radiator, engine block and heater system) is empty it will take 11 to 12 qts to refill (this also depends on what engine you have and if it has ac or not). If you only drain the radiator, aprox 5 qts.
looks like cilinder head gasket is defect, engine pressure is coming in radiator, and cooling fluid goes into motor
Unless your radiator has a leak, the radiator fluid stays in the radiator.
radiator fluid
Your radiator appears empty because your cooling system has a leak.
Your car will leak anti-freeze/coolant. If you run out of fluid in your radiator then your car will overheat in a short period and cause much more damage. Fix your radiator!
Might depend on HOW MUCH brake fluid you put in there, but not much. The radiator holds quite a lot of mostly water, so a dash of brake fluid will quickly become very diluted. But since the radiator doesn't expect brake fluid, it'd make sense to have it flushed and refilled as soon as possible.
Where is the radiator to put fluid for 2001 jetta?
you have to put the radiator fluid in the overflow. This is the only way.
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.
Cracked radiator end caps since the tranny fluid runs goes threw the caps for cooling that is the only way tranny fluid can get in the radiator
