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..
I had been driving for an hour when I noticed the red blinking coolant light.
Since I was only 1/4 mile away from home, I drove home. When I checked the car in the driveway, there were "steam" coming out from both vents. I put the car in the garage and saw a trail of coolant so I placed a cardboard under the car.

The current state.
1. The coolant tank is empty.
2. The cardboard has only a few drops. Nothing significant.
3. Bought a Radiator Pressure Leakage Tester but can't build up pressure.
4. Removed the under cover and saw coolant.
5. Nothing obvious wrong with WP or the hoses.
6. Started the car to see if there were any leaks. No leaks. (The rear was up when I did this so maybe what coolant left was moved to the front of the car?)

Next, I am now going to fill the coolant tank, distilled water?, and see if there is any leakage.

Wish me luck!
