Hi. The level of coolant in the engine of my V6 VE Commodore keeps dropping.
The cooling system has no leaks and does not lose coolant, the engine has no overheating problems. I remove the pressure cap off the engine and fill it to the top with coolant. When the engine gets hot the coolant expands and goes into the expansion bottle but when it cools down it does not draw the coolant back into the engine, when checked cold the level in the engine is low and the expansion bottle now has that excess coolant in it . I have tried two new pressure caps, the sealing surface where the cap goes in the housing is okay, the hose to the expansion bottle has no leaks in it. It loses no volume of coolant , after 3-4 days i suck the excess coolant out of the expansion bottle and put it back in he engine and it starts all over again.
I have had the vehicle to a Holden dealership and two other workshops and no one can find any faults or work out the problem. Has any one experienced this problem . Appreciate any ideas . Cheers Gary
