Tools and Materials Needed

  • Mishimoto M12 radiator
  • Socket set
  • Wrench set
  • Flathead screwdriver
  • Phillips screwdriver
  • Coolant
  • Drip pan
  • Shop towels
  • Safety gloves
  • Safety glasses

Preparation Steps

Before starting the installation, ensure you have all the necessary tools and materials at hand. It is also essential to work in a well-ventilated area and wear appropriate safety gear.

1. Safety First

Put on your safety gloves and glasses. This will protect you from any sharp edges or harmful substances during the installation process.

2. Let the Engine Cool

Ensure that the engine is completely cool before starting. This will prevent burns and make the process easier.

Draining the Old Coolant

To begin the installation, you must drain the old coolant from the radiator. Follow these steps carefully.

1. Locate the Drain Plug

Find the drain plug at the bottom of the radiator. Place a drip pan underneath to catch the old coolant.

2. Open the Drain Plug

Using a wrench, carefully open the drain plug and allow the coolant to flow into the pan. Make sure to dispose of the old coolant properly.

Removing the Old Radiator

Once the old coolant is drained, you can remove the old radiator from your vehicle. Follow these steps for a successful removal.

1. Disconnect the Hoses

Start by disconnecting the upper and lower radiator hoses. Use a flathead screwdriver to loosen the clamps and pull the hoses off.

2. Remove the Fan Shroud

Next, remove the fan shroud by unscrewing any bolts or clips that hold it in place. Carefully lift it out to avoid damaging any components.

3. Unbolt the Radiator

Locate the bolts securing the radiator to the vehicle. Using a socket set, remove these bolts and carefully lift the radiator out.

Installing the Mishimoto M12 Radiator

With the old radiator removed, you can now install the new Mishimoto M12 radiator. Follow these steps to ensure a proper fit.

1. Position the New Radiator

Carefully position the new radiator into the mounting brackets. Ensure it is aligned correctly before securing it in place.

2. Bolt the Radiator in Place

Using the socket set, tighten the bolts to secure the radiator. Make sure it is firmly in place, but avoid over-tightening.

3. Reattach the Fan Shroud

Reinstall the fan shroud by securing it with the previously removed bolts or clips. Ensure it is fitted correctly to avoid interference with the radiator.

4. Connect the Hoses

Reconnect the upper and lower radiator hoses. Ensure the clamps are tight to prevent any leaks.

Refilling the Coolant

After the radiator is installed, you need to refill the coolant to ensure proper functioning.

1. Prepare the Coolant

Mix the coolant according to the manufacturer’s instructions. Ensure you have the correct type for your vehicle.

2. Fill the Radiator

Slowly pour the coolant into the radiator until it reaches the recommended level. Avoid overfilling.

3. Bleed the System

Start the engine and allow it to run for a few minutes. This will help bleed any air from the system. Check for leaks during this process.

Final Checks

Once everything is reassembled, perform a final check to ensure everything is in order.

1. Inspect for Leaks

Check all hose connections and the radiator for any signs of leaks. Address any issues before driving the vehicle.

2. Test Drive

Take the vehicle for a short test drive to ensure everything is functioning correctly. Monitor the temperature gauge to ensure it stays within the normal range.

Conclusion

Installing the Mishimoto M12 radiator can lead to significant performance gains, including a boost of 20 horsepower. By following these step-by-step instructions, you can ensure a successful installation and enjoy the benefits of your upgraded cooling system.
