Hi Ismael, the first thing to thank your answer thanks, in the direction of the Opel a slightly weird case happens to me and that when I turn left sometimes it sounds as if it lacked liquid and the direction is tough and at the moment it becomes well again, the case that I have looked at the level of the liquid of the address and the level is correct, I have been watching and I do not notice any loss of liquid by any side, apart from that fault, apart from that fault, apart from that fault. An invisible water leak because I do not find it anywhere, I deduce that it can be the water pump since it only loses water when it is torn and stains the area above the gearbox and I would like to know how I can see if the fault is of the pump and how to change it in case it is the pump since this car does not have distribution but it does not have a chain and I have never touched an engine with chain, so those are my doubts. You can help me, thanks.
