Step 1: Gather Your Tools and Materials

Before starting the replacement, ensure you have the following items ready:

• PEAK OET Antifreeze and Coolant (50/50 premixed)
• FloTool Less Mess Oil Drain
• Basic tools: socket set, wrench, screwdriver
• Safety equipment: gloves and goggles

Step 2: Prepare the Vehicle

1. Safety First: Make sure the engine is completely cool before you begin working.
2. Disconnect the Battery: Remove the negative terminal from the battery to prevent any electrical issues.
3. Lift the Vehicle: Use a jack to raise the front of the vehicle and secure it with jack stands for safety.

Step 3: Drain the Coolant

1. Locate the Drain Plug: Find the radiator drain plug, usually located at the bottom of the radiator.
2. Position the Oil Drain Pan: Place the FloTool Less Mess Oil Drain under the drain plug.
3. Open the Drain Plug: Carefully open the drain plug to allow old coolant to flow into the pan. Dispose of the used coolant properly.

Step 4: Remove the Old Thermostat

1. Locate the Thermostat Housing: The thermostat is usually located near the engine block, connected to the upper radiator hose.
2. Unbolt the Housing: Use a socket wrench to remove the bolts securing the thermostat housing.
3. Take Out the Old Thermostat: Carefully lift the thermostat out of its housing. Check for any gasket material that may need cleaning.

Step 5: Install the New Thermostat

1. Prepare the New Thermostat: Compare the old thermostat with the new one to ensure it is the correct part.
2. Position the New Thermostat: Place the new thermostat into the housing, ensuring it's seated properly.
3. Reattach the Housing: Bolt the thermostat housing back into place securely.

Step 6: Refill the Cooling System

1. Replace the Drain Plug: Once the thermostat is in place, close the radiator drain plug.
2. Add New Coolant: Pour the PEAK OET Antifreeze and Coolant into the radiator until it reaches the proper level.
3. Bleed the Cooling System: Start the engine and let it run for a few minutes to allow the new coolant to circulate. Check for any leaks around the thermostat housing.

Step 7: Reconnect the Battery and Test

1. Reconnect the Battery: Attach the negative terminal back to the battery.
2. Test Drive: Take the vehicle for a short drive to ensure the engine runs at the correct temperature and monitor for any leaks.
