If you are loosing coolant and the reserve tank remains the same, it could mean the following :
1. Bad radiator cap.
2. Leaks in hose from radiator to reserve tank.
3. Excessive air in system.
4. Bad head gasket. This problem usually increases the coolant level in reserve tank.
5. Fast leaks in cooling system.
If it is a bad head gasket, repairs can be more than $1,000.00 depending on what needs to be done.
A pressure test would determine if the system is leaking.
To check if the head gasket is bad, here is a simple way.
Ensure there are no air in cooling system. Run engine with radiator cap open and top up if necessary. If coolant level does not drop, close radiator cap.
Remove hose from reserve tank.
Insert hose into a transparent botle filled with water.
Start and run engine.
Run till radiator fan comes on.
If there are bubbles in the bottle, run for a while longer until the air has been bled out of cooling system.
If bubbles continues and does not stop, the head gasket is bad.
Try sudden reving of the engine and note if the bubbles increases at that instance. If yes, gasket is bad and compression is leaking.
And use a transparent bottle filled with water.
