Car problem leaking coolant...plz help!!?

Question

ok so my car is leaking coolant, it take about 7 days for it to go from full to the point where the low coolant light comes on. i cannot visually see the leak, and i have not seen any puddles on the ground...what is going on hear...and does anyone know how much it may cost to fix?

Answer 1

Check to see if it is mixing with either the oil or transmission fluid.

Answer 2

if you do not see any leaks that leaves three possibilities.

1) if the oil looks milky, then you have a blown head gasket or cracked block or cracked head.

2) if you have pink milky transmission fluid, then the trans cooler has ruptured in the radiator, time to replace a radiator and to flush the transmission and keep your fingers crossed.

3) if you feel the carpet below the heater housing on the passenger side and it feels wet, them the heater core has a hole in it.

these are just the top three that i can think of at this point.  

Answer 3

without any puddles on the ground to indicate where the leak is coming from and no visual leaks on the engine the next thought that comes to my mind is that you have a leaky head gasket. what this means is that water is leaking into the combustion chamber in the engine and getting burned off with the fuel. leaky head gaskets can sometimes have there life prolonged by adding stop leak to the radiator, but i wouldn't suggest it. a proper head gasket change can be quite expensive depending on the car.

Answer 4

coolant leaks are usually very easy fixes, but sometimes can be tough.  If you notice white smoke coming form your exhaust then you have a blown head gasket and that is a pain, and would also explain why you don't see a puddle when you park, but if thats not the case then to fix a leak in your cooling system it is usually inexpensive, unless again it is a head gasket
