Hi,
You listed this as a 4 cylinder, but the only engine offered in the Quest this year was a 3.0L V6. I am going to provide the directions specific to replacement on the 3.0L which I believe you have.
The directions also explain how to check your old thermostat after it's removed.

3. Install thermostat with jiggle valve or air bleeder at upper side.
4. Install water outlet housing.
5. Install water hose to water outlet housing.
6. Refill engine coolant.
- After installation, run engine for a few minutes, and check for leaks.
__________________________
Note: Make sure the jiggle valve is in the 12 o'clock position (pic 5). Otherwise, it will be very difficult to get the air out of the system.
Let me know if this helps.
Take care,
Joe
