If coolant isn't leaking externally then it has to be leaking internally. A leaking head gasket or cracked head may be the problem. If this is the case, as it gets worse more coolant will enter the combustion chamber or engine oil. Either way you will be able to determine as it gets worse. There will be white smoke from the exhaust. May be intermittent. This is if coolant is leaking into combustion chamber. If leaking into oil, you will notice that the engine oil will have a brown/milky look to it as you check the oil level on the engine oil dipstick.
No, it can't. Not from the oil cooler.
Just because there is a leak doesn't mean it will overheat instantly, but if you do not keep adding coolant or fix the leak you will have engine problem
If a vehicle is loosing coolant then there is a leak. If no leak is visible then the coolant could be leaking into the oil, or leaking into a cylinder and being blown out through the exhaust.
You have a coolant leak.You have a coolant leak.
As long as you can keep adding coolant to it.
because may need topping up. if you top up and still the light comes on, you may have a leak somewhere. get checked out asap.
Maintaining the fluids in the cars is important. A person has to keep replacing the coolant fluid because the car is using it or because there is a leak.
It is possible if the leak is a "internal leak" - where the coolant is leaking inside the motor and mixing with the oil it will ruin the motor. This will eventually cause bearing failure. If it is an external leak - as long as you keep the coolant full and watch your temp gauge, you can get by for a while. Keep in mind - the leak will only get worse as time goes on.
Because some opening formed which is allowing coolant to leak out.
The coolant will normally leak into the oil or into the cylinder
Any coolant leak can cause an overheat.Any coolant leak can cause an overheat.
Yes, the water pump can leak if you do a coolant flush.
