Featuring a durable brass body, standard 1/8 inch thread, and a fast 10-second thermal response, it’s engineered for reliable coolant, water, and oil temperature monitoring in demanding automotive applications. ## Description This product has sensor performance specifications with accuracy of more than 2 degree centigrade / 3.6 degree Fahrenheit and operating temperature of - 40 Celsius to 200 Celsius / -40 Fahrenheit to 392 Fahrenheit. The dissipation constant is 12 megawatt per degree centigrade and the ratio, at a specified ambient temperature, of the change in the power dissipation of the sensor to the resultant temperature change of the Thermistor. The test medium is silicone oil and thermal time constant is 10 sec. The time required for the sensor to achieve 63.2 per cent of its steady state value when subjected to a step change in ambient temperature [Tc= (Tf-Ti) x63.2%+Ti]. Sensor body material used is brass, thread: 1/8 inches -27 PTF, hex size is 1/2 inches, installation torque: 13.5Nm / 10 feet-pounds, weight of 12.2 grams, supply current: 5 Volt DC, electric termination: connector includes mating connector, pins and pin lock. Review: It has a datasheet so it's nice an easy to use/map anywhere. Good quality product. Temp/resistance values have a slight curve. Check out the data sheet to make sure it works for you. Review: Works as advertised. ## Features - One wire to sensor ground and one wire to sensor signal - Wire strip length is 0.175 inches to 0.200 inches - Thread size: 1/8 inches - Operating temperature: sensor tip -40C to 200C, connector -40C to 150C ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005AT11F4 | | Best Sellers Rank | 578,408 in Automotive ( See Top 100 in Automotive ) 805 in Car Coolant Temperature Sensors | | Brand | AEM | | Customer Reviews | 4.4 4.4 out of 5 stars (54) | | Date First Available | 8 Aug. 2012 | | Item Weight | 40 g | | Item model number | 30-2012 | | Manufacturer | AEM | | Manufacturer part number | 30-2012 | | Model | AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit | | OEM Part Number | 30-2012 | | Product Dimensions | 12 x 7 x 12 cm; 40 g | | Voltage | 12 Volts | ## Product Details - **Brand:** AEM - **Item dimensions L x W x H:** 12 x 7 x 12 centimetres - **Item weight:** 0.04 Kilograms - **Material:** Brass Aluminum - **Style:** Thermal ## Images ![30-2012 Water/Coolant/Oil Temperature Sensor Kit - Image 1](https://m.media-amazon.com/images/I/61BmTZtBD+L.jpg) ## Questions & Answers **Q: What is the ohm resistance on this sensor?** A: packard makes the original part 12160855,, you can find specs at mouser,, i could find no reference to ohm resistance **Q: Will this oil temp sending unit fit my 2005 nissan fronteir Nismo cre** A: It is unlikely to work with the stock threads and ECU. If you are using an aftermarket or AEM gauge, you can just get a thread adapter or if you are making an new hole, you can drill and tap it. The adapter is a common method to use US based gauges on Japanese vehicles with metric threads. **Q: Will this work with my AEM 30-5140 100-300F temperature gauge?** A: Yes AEM uses the same probe on their temp gauges **Q: Is this sensor 1/8 npt or 1/8 bspt?** A: The thread size is 1/8" - 27 NPTF ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***T on 27 February 2015* It has a datasheet so it's nice an easy to use/map anywhere. Good quality product. Temp/resistance values have a slight curve. Check out the data sheet to make sure it works for you. ### ⭐⭐⭐⭐⭐ Review *by J***9 on 1 August 2018* Works as advertised. ### ⭐⭐ Review *by J***D on 9 September 2023* Calibrated based upon aem 30-2012. At ambient temp it is 20deg c lower then all other temp sensors in the engine bay. For the price do not buy it. ## Frequently Bought Together - AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit - AEM 30-2131-150 150 PSIG Brass Sensor Kit - AEM 30-2131-100 100 PSIG Brass Sensor Kit --- ## 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.co.uk/products/52713884-30-2012-water-coolant-oil-temperature-sensor-kit](https://www.desertcart.co.uk/products/52713884-30-2012-water-coolant-oil-temperature-sensor-kit) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
