Hi. I'm quite new here but looking for some information about coolant drain plug location on the block (if there is any). I have located the one at the bottom of the radiator (blue plastic screw). It seems I can only flush out about 5 litres of coolant from that plug. I was changing the upper hose (from mechanical pump to top of radiator) as the o-ring was leaking coolant. Also as described the little hose that runs off the side of this plastic housing broke when I moved it (very brittle). Great info and very informative. I will look into replacing the temperature sensor also.
