Low Coolant Fault
I have an 04 GXP and the other night when moving the cars around and the car was running for about 2 minutes, a Low Engine Coolant error flashed on to the DIC. It was late and dark but there was no coolant on the ground. I thought I would look in the morning but forgot at first when starting the car, well the error popped up within in a minute while still in the driveway. So I got a flashlight and checked the recovery/overflow tank (the only place you can) and the level seemed to be within a 1/2 inch of the cold level. So I put the cap back on and thought that was hard to turn and it had been easy to take off. So maybe it wasn't on tight to start. Have had the car for 3 months and 10000km (6000miles) and have not had this error before.
Made sure the cap was tight and have driven for 2 days with no reocurance,
So my question is, will a loose cap and no pressure cause this problem? Both times this occured the engine was stone cold so there would have been no chance for pressure to build.
