How do you change the engine temp sending unit on an 88 Honda CRX SI?

: First have always a #10 and 14 wrench. Take the distributor out and have a towel or rag to clean some oil drips. Place it aside and just beneath you will see the sending unit. Sometimes it is just a matter of replacing but the gauges can be already fatigue. However the sending unit is your cheapest beginning. be careful with the plug when disconnecting.
