There can be a number of reasons, from a hole in the rad or pipes, up to a cracked head or head gasket. Try to locate the leak and go from there.
It would greatly depend on the source of the leak, need more info.
Some foreign car makers use a purple colored anti-freeze, so my guess would be you have an coolant leak.
vacuum leak.
it will leak from the positive connection becauase the positive connection is what is under place of the acid
The transmission will not work without fluid.
There could be a hole in the hose or the hose is not secured properly.
Depends on the make and model of the car.
A vacuum leak is one possibility.
Yes glycol (used in anitfreeze) is flammable
could be a number of things if the leak is inside of the car it is your heater core. if it is outsidt the car under the hood it could be one of your hoses the water pump a freeze plug could be a head gasket or maybe even an intake gasket hard to say without actually seeing the car i wold pressure test the cooling system and see if you can find the leak that way
when you drive with an oil leak the oil drips onto the road and makes the road surface slippery for motor cycles and other vehicles.
A large vacuum leak could do that.
There must be a crank case leak, or the oil pan plug is gone.
YES. Good possibility if it is leaking at the passenger side
I don't recommend any of those products, they tend to create clogs or reduce efficiency. Just have the leak fixed since it's usually pretty cheap to have done.
It depends on where the leak is and what is causing the leak.
exhaust leak or fuel leak
