The cluster gauge is dummy gauge, or at least on my 2008 model.
I drove it with temp displayed on climatronic and when going downhill engine cooled down to 75C, the dash gauge did not drop from 82C.
Water pumps can outlast the car, so you never know.
The best preemptive repair is get a new car.
For me the water pump is now a maintenace item. If you have a second car to drive, someone to come and get you when you break down, and live near a dealer, dont travel far from home, etc them ok maybe not, butFor me a water pump is not a maintenance item....if it ain't broke ,,dont fix it..
One very cold and snowy Friday evening and several hundred miles from home, my low coolant warning came on, had to stop at three different connivence stores before i could get even a gallon of distilled water. Found a dealer, 50 miles away, just before closing, they didnt have a pump in stock, werent sure when it would come in because it was during Christmas/New Year holidays and they were backlogged a week so next Friday. So only bought coolant from the dealer. I ordered a pump from FCP while sitting at the dealers. Went to A grocery that was closed but I snuck in through the out door, a self checkout register was lit, so I managed to buy 5 gallons of distilled, by the time I got home at midnight I had used 4.5 gallons. I got the pump Monday dec 31, and put it on, wasn’t too diificult, have to pull the fan. And make sure there is no grime and grit under the high pressure fuel pump. This is why its a maintenance item for me from now on.
