My left foot was soaked by scalding antifreeze, leaking out of the heater next to my foot. The pipes to the heat exchanger (if that is what it is called) aren't the culprits. So I can only assume it is the heat exchanger (there's that word again) that needs replacing - for clarification, as I dont know how to post pics (1) it wouldn't accept a 157kb photo and 2)I dont have a website), this is next to the fan, just below the windscreen. But how on earth do you get it out? I've taken out a lot of screws but cannot see what else I need to do to get it out. All thoughts/help greatly appreciated!
