Great deal, works in 2003 Civic
Fit and worked like a charm, and still is even today. I’m really happy with the DOICOO coolant temperature sensor so far. At the time I needed, my car's engine could not register a temperature. It turned out to be a simple, reliable fix for an issue that had been bugging my Civic for weeks. The mechanic said the installation was easy, and the sensor fit perfectly without any modifications. Before replacing it, as previously stated, my temperature gauge was acting strange, and the engine fan wasn’t kicking on at the right times. In fact, the engine could begin to run hot fairly quickly because of a faulty sensor. After installing this sensor, everything went back to normal, steady temperature readings, smoother idle, and no more unexpected fan behavior. For the price to pay and cheap mechanic labor, I couldn't have gotten a better deal anywhere else! The DOICOO 37870-PNA-003 37870-PLC-004 Coolant Temperature Sensor was a good fair price and I recommend it if you drive a 2003 Honda Civic. It been working inside the vehicle for about 6 months and the durability is super!

Le doy 4 estrellas porque tal vez fue mi culpa que lo apreté un poco duro y se partió, como no estoy seguro si fue que su material es blando ahí lo dejo

Very weak product. It broke by the thread while tightening. Had to use a screwdriver to take the piece out that was stuck in the housing. Stay away from this product. There are similar reviews about the same issue. Wish had seen them earlier. Would never buy this.
