Now I know replacing a radiator is pretty straight forward but on this particular model it's a little more complicated with the "modular" system, as it seemed overly complicated to me a tech and might be daunting to a DIY. Now that I have done 10 or so of these over the years I figured I would make a video of the procedure from start to finish. Hope this helps as this can be a costly repair, but doesn't have to be.
