Just getting to 153,000 miles, never replaced the water pump or thermostat. Just noticed that you guys are all on FX35's. Ay idea if the same recommendation goes for the '45?
Most of the time a water pump goes, it is either a leaky shaft seal, or a broken or worn impeller. I'd have to look at the manual to see what is affected by the gasket. It seems weird that a failed gasket would contaminate the crankcase
Probably going to proactively change the radiator hoses, thermostat and a few other things when I change the plugs and the serpentine belt during this summer. I'll evaluate then whether I want to change the water pump as well.
Right now, I concentrating on replacing the front wheel bearing hub assemblies, and deciding what tires I want to go to instead of the Goodyear Eagles.
