I had my water pump replaced at around 119k miles and at the time I had the pump, gasket and coolant replaced. I have a spare expansion tank for when mine goes kaput, but the system was pressure tested and the old tank is still holding just fine.

I can't remember if I had the thermostat replaced.. but if it wasn't the current one is around 5 years old.

Mike out of curiosity what are the symptoms that led to you replacing the water pump? Mine got a small leak on the surface where the pump mounts and was dripping pretty bad. I only noticed when my overheating/coolant light on the dash was blinking on a cold start. Then I saw the puddle..
