My Daihatsu Pyzar (Gran Move) is overheationg, once it gets halfway on the temperature gauge it starts to miss, have taken the centre out of the thermostat unit, and replaced the ring back to try to get the temperature down, still seems to be getting very hot. 5mins it heats up. And the fan doesnt seem to kick in early enough and only for a short time. Ive been looking all over the internet for a manual but cant find an english one, does anyone know where to download the manual. Thanks
