As a proactive changeout, I'm replacing the 17 year old radiator fan motor in my Honda civic 1999. The new motor I got off Amazon.com.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Removing the Fan Assembly.
The upper radiator hose must be disconnected at the radiator or removed completely. The electrical connector need to be unclipped and the two 10mm bolts at the top of the fan assembly be removed.
Step 2: Removing the Motor.
An 8mm nut holds the fan blade to the motor shaft. 3 Phillips head screws hold the motor to the shroud.
Once out the oem motor is in great condition and will be cleaned up for storage.
Step 3: Comparison.
The new motor is slightly smaller. I hope it uses less power too.
Step 4: Preparing the New Motor.
Since the new motor didn't come with the electrical connector, I had to cut and solder the oem one. I reused the same wire sleeve as well. Liquid tape was used to insulate the joints.
Step 5: Storing the Oem Motor.
As a good spare, I degreased the casing of the oem motor and put it away.
Step 6: Reassembly of the Fan.
The reverse of removal. The new motor is now in.
Step 7: Installing the Fan Assembly.
The two 10mm at the base of the radiator were tightened snug and the upper two 10mm bolts installed to hold the fan shroud onto the radiator. The electrical connector was reattached.
Step 8: Completion!
Now my car has a new radiator fan motor and should give me added reliability!
