Ok I've been putting this job off for 3 years as i've been told its a pig of a job..... but after succesfully installing an altornator this morning i was on a roll!!

Can someone please explain a) what the feck this thing is and b) how do i remove it to get to the heater matrix

Pictures taken from divers side foot well, just behind the stereo!



Inlet and outlet water pipes i guess?



Lots of black plastic, how do remove this???



I can only find one bolt at the very top, but i'm sure thats not the only thing holding it in place







HELP!!!!!!!!!
