The cars a 97 sohc XL(Australian accent). Where do I locate the engine drain plug. It says in the manual to remove it. The radiator drain plug location is simple enough but where would I find the coolant drain plug for the engine. Nothing in my workshop manual so it must be obvious but id like to know before i put it up on a hoist. I also thought there would be some sort of air bleed at the highest point of the coolant system but there doesnt seem to be any mention of this. Also any recommendations on the type of coolant flush to use.
