Yes, anti clockwise it is!
I'm using an old KIA Carnival as my work van currently and I took it to the KIA dealer for a service & new timing belts as I didn't have the time to do it myself. Anyway, when I picked up the car, I noticed they had charged me for a Helicoil. It turned out their mechanics use rattle guns to remove the sump plugs and this time the mechanic forgot to put it in reverse & destroyed the thread in the aluminium sump! They also said there was a rattle from the engine and they'd need to pull the engine apart to investigate. In the end I paid & never went back. The rattle turned out to be a ring spanner down in the valley of the engine that someone had dropped. They also didn't change the oil filter at the service & the fuel injectors blocked because the fuel filter hadn't been changed...
