Before beginning this procedure, ensure you allow your engine to completely cool down. The system is pressured and if you remove your temperature sender while it is still hot, coolant will spray out and potentially cause severe burns.

WARNING: This procedure was performed on my 2001 Volkswagen Jetta 1.8T. I cannot gaurantee this will work on your vehicle. Work at your own risk. It took me about 5-10 minutes to complete this.


Step#1: Remove the upper and lower engine covers to allow easy access of the temperature sender.

Step #2: Remove the retaining clip that secures the temperature sender in place. Slide the pick into the small portion of the clip that can be seen. (between the plastic housing and edge of retaining clip). Pull the clip straight out with minimal force.
