No offense to Jake Raby but he is in business to make money and his recommendation is no more or less significant than Porsche not having a water pump replacement as a maintenance item. My water pump went 84K miles before the tell tale bearing squeal started and I drove it to the shop that replaced it without damage. If you do replace it do use an OEM pump as the third party one's are not worth the few dollars you will save. As far as the LN 160 deg. thermostat I'm also on the side of keeping the 180 deg. as all cars are designed to operate at a specific warmup and operating temp to reduce emissions and to keep combustion at a maximum so deposits don't build up.
