I located my sensor in the top radiator hose so I know what the temp is of the coolant as it is leaving the engine headed towards the radiator. This also tells you when your thermostate opens, mine should open at 192. This is relative to where the temp gauge reads. If I am hauling a load the temp goes up slightly with in 2-5 degrees. People complain the temp gauge doesn't read below 104, Why do you need it to read below 104? The gauge isn't going to read right off until the coolant is warm over 104 and the thermostate STARTS to open. The CONs I had was the wiring harness is too short, could have been 6-8 foot long and you could cut as needed. Currently harness is 12 inches long and you have to extend them. The other CON is the wires are like 22 - 24 gauge, very small to adapt too but it can be done. I broke my joints the first time had to resplice them. The Housing is all plastic, not a game changer for an old everyday truck but for a classic I wouldn't use it. Also not recommended for direct outdoor use with No cab or protection Other than the three CONS, good gauge for the money. You got to be smarter than what you are working with. If you are installing in line in a rubber radiator hose the sensors body has got to be ground for the gauge to work. I would recommend it if the situation is RIGHT. Review: Works great! After figuring what I did wrong! - The gauge works as it should. At first it only read 104..wouldn’t move. desertcart was going to send me a new one. Then I read the reviews and saw the same issue, as well as others. I figured it was maybe user error. So I used a new wire between the sending unit and the gauge. Then it read higher temps as the engine heated up. Noticed that the gauge would jump around a bit higher ,then lower. Ran new wires to serve this unit only where as before I was using existing wires from another gauge.That was the problem. Works great now. So in my case, and maybe some of the other bad reviews…was due to user error. ## Features - Unit:°F(Fahrenheit) - READ:104-300 - Power:Professional 12V,IGN MAX 0.3A - Size:2 inch gauge or 52 mm diameter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008FXJS9I | | Best Sellers Rank | #1,723,836 in Automotive ( See Top 100 in Automotive ) #355 in Automotive Water Temperature Gauges | | Brand Name | HOTSYSTEM | | Customer Reviews | 4.0 4.0 out of 5 stars (1,007) | | Item Dimensions | 6.6 x 5.3 x 3.4 inches | | Item Weight | 8.8 ounces | | Manufacturer | nj365 | | Material Type | PVC, Plastic | | UPC | 610395316374 639713222623 | | Unit Count | 1 Count | ## Product Details - **Brand:** HOTSYSTEM - **Item Weight:** 8.8 ounces - **Item dimensions L x W x H:** 6.6 x 5.3 x 3.4 inches - **Material:** PVC, Plastic - **Thread Type:** Npt ## Images ![Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - Image 1](https://m.media-amazon.com/images/I/61iWxnGKxKL.jpg) ![Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - Image 2](https://m.media-amazon.com/images/I/71bIW0geB9L.jpg) ![Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - Image 3](https://m.media-amazon.com/images/I/61jFgIdzyfL.jpg) ![Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - Image 4](https://m.media-amazon.com/images/I/61x2omo3JuL.jpg) ![Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - Image 5](https://m.media-amazon.com/images/I/51y627CJd2L.jpg) ## Questions & Answers **Q: Can this be used as a oil temp guage. I'm only asking because I couldn't find an oil guage that read in deg F** A: As long as the gauge reads in the temp range that you want, I don't see why the sensor wouldn't work. It's immersed in a liquid, so shouldn't matter whether coolant or oil. **Q: This is going on a 1973 bug what is the limit on how hot the gauge can go? I've read 3?? can you please just let me know normal temp is 300 to 310** A: No offense, but a '73 bug is an air-cooled engine. This is designed to monitor the cooling water for a water-cooled engine, and it has an alarm at 212 degrees F. On an air-cooled angine, you can only monitor the oil temperature or the cylinder head temperature. **Q: Why does the temp stay at 104 ? I checked it with a lazer thermometer and it reads higher than that** A: That is the starting reading 104 does not read lower **Q: I installed this gauge recently and now gauge is locked at 304 reading. Is it thegauge or sender?** A: Please check the sensor installed correctly,and if it still display304 please contact us again,click link below,We will offer a good solution https://www.amazon.com/ss/help/contact/?_encoding=UTF8&marketplaceID=ATVPDKIKX0DER&ref_=v_sp_contact_seller&sellerID=A23ZC5CAWCCWWE ## Customer Reviews ### ⭐⭐⭐⭐⭐ The price is right! *by C***R on January 30, 2022* I feel this is very accurate.

The gauge is decent however the sensor took a poop after 2 weeks and Amazon quickly shipped out a replacement. Minutes ago I installed the new sensor and it works. We'll see how long it will last. Also the probe on the sensor needs to be a bit longer. I will post a follow up one month from now (if it lasts) ## Frequently Bought Together - HOTSYSTEM Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - HOTSYSTEM Electronic Voltmeter Voltage Volt Gauge Meter Blue Digital LED 2inches 52mm for Car Vehicle Auto - ESUPPORT Car 2" 52mm Digital Oil Press Pressure Gauge Blue LED --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/1218540-universal-water-temp-gauge-temperature-meter-electronic-blue-digital-led](https://www.desertcart.id/products/1218540-universal-water-temp-gauge-temperature-meter-electronic-blue-digital-led) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-04-27*
