You didn't mention the engine so.....
Thermostat
REMOVAL & INSTALLATION
CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

2.0L and 2.5L Engines
Disconnect the negative battery cable.
Remove the thermostat housing cap.
Grasp the handle of the thermostat, then gently pull it upwards to remove. Remove the gasket/O-ring and replace if damaged.
Clean off the thermostat housing and O-ring. After cleaning, apply a suitable lubricant to the O-ring to aid in installation.
To install:

Place the thermostat in the housing, pushing down to be sure it is firmly seated.
Install the thermostat housing cap.
Properly fill the cooling system.
Connect the negative battery cable, remove the radiator cap, then start the engine. Allow the engine to run with radiator cap removed, until the upper radiator hose becomes hot (thermostat open). With the engine idling, add coolant to the radiator until the level is up to the bottom of the filler neck.
Install the radiator cap.
