This is a reliable and accurate gauge.Just be sure to note that it reads in metric Celsius/Centigrade.The warning light comes on at 100° C.Hook up was easy. The temp sender is 1/4 NPT. If using Teflon tape be sure to NOT wrap the end of the sensor.Be careful when installing as the electrical connection stud on the sensor is easily damaged. This is not a failing of the product just inherent in the design. Be sure to use a deep enough socket when installing so there is no pressure on that stud when installing.The included cable is only a few inches long so you will need extra wire for the sensor and/or electrical connection.There are three wires: black (-) & red (+) for power and a green sensor wire

Bought this for a water cooling project. I needed something cheap and easy to read. I accidently ordered Celsius when I needed Fahrenheit. No biggie I need to learn the metric system anyway.

there good gauges and they do work and they are really nice. but the company dont tell you on amazon that you have to buy extra parts some where else to get them to fit right inn the block. check before you buy these.

I recently purchased this HOTSYSTEM water temperature gauge for my car, and despite a small incident that occurred during shipping concerning an incorrect gauge, I cannot be more satisfied with my purchase of this water gauge. Not only are HOTSYSTEM gauges very high quality performance parts, but the customer service on their end is absolutely phenomenal. The people there at HOTSYSTEM worked with me as quickly as possible to replace and reship the guage that I originally ordered. I highly recommend this gauge and this company! I am truly grateful and impressed!

I bought 3 diffrent guages from this company and all three are increadibly in acurate. The tach jumps around and only shows the rpm half the time and when it does its normaly off by 1k. The water temp is off by 40 degrees. The oil pressure guage works sometimes when it feels like it. All worthless.

It's in Celsius not Fahrenheit, so if you dont know the conversion might suggest looking for a Fahrenheit guage.
