Prepare the Volvo for the next 800t km

Hello Volvofans, I have been reading this forum for some time and have now signed up. Thank you for the many useful tips! Our Volvo V70 TDI (MJ97, D5252T MSA15.7) has exceeded the 800,000 km mark (see picture) last week. There are a few repairs to be done in the summer when I have time. I need information beforehand and hope for your help. 1) Motor suspensions / engine cushions The engine suspensions or engine cushions are worn out and The following parts are/should be changed: I would like to use the original parts or parts of the manufacturer who made these bearings/cushions for Volvo. Since the spare parts are probably cheaper with the supplier of Volvo, the question: Who produced the bearings/cushions for Volvo? 2) Change heat exchanger The heat exchanger for the interior must be replaced. Which spare part is recommended? The original heat exchanger will be replaced over time and Is there a better heat exchanger that no longer has this problem? 3) Since the water cooler is leaking, I would like to replace it. I have selected the following parts for the exchange (number I have not listed): Since I want to buy the spare parts before, the question: Did I forget something? 4) Which part number have the protective adhesives ifen for the front mud flaps? I would like to thank you in advance for your help!
