there are HG test kits, they sample the coolant and check for oil/hydrocarbons etc usually Any colour change - suspect hg, might be worth dropping some £ on one of those as a first step.
if thats ok and 1 pot is still awol perhaps compression test time
then its Cleaning the pipe work time,, theres going to be oily "oh dear me" in there, and possibly the intercooler as well,, rubber gloves and cleaning time
plugs wise
its a Volvo, there are "alternative" plugs out there and they work, sort of mostly, so Gen volvo plugs for it rather than "ngk /etc" check the coil packs as your going
suspension
drop links? track rod ends? snapped spring? shock top mount,, or loose wheel nuts *its been known,,
id not fuss too much on the belly pan being awol untill you have gotten all the gremlins sorted
IF you intend to keep the car and diy service it etc (assuming the HG is fine that is)
have a look at VIDA + a laptop/tablet to run it on ,,forget using generic ODB readers its a volvo , vida will do a Lot more than just diag faults, there is a Total how to for taking everything off and back on the car included
