Review: Aisin or nothing - Delivered on time and is to OE standard for those of you who don’t know, Aisin, is the OE manufacturer for Toyota when it comes to water pumps and thermostats. Great quality. Gasket needs to be purchased separately. I would recommend Aisin above Gates, etc when it comes to this particular part. Also, if you’re changing the water pump you might as well change the thermostat as well so you don’t have to refill the coolant twice. Review: High Quality Thermostat - Tested sat out of the box for once, I've tried a lot of thermostat brands (even Napa) and they are very hit or miss these days. Quality control since the pandemic has been atrociously worse. Aisin however has remained top notch. Opens right at the advertised temp and opens linearly until maximum opening, and reliably opens and closes effectively. Works well. Don't forget a thermostat gasket if you need one (but don't add one if you don't!) ## Features - Aisin OE matched engine coolant thermostats are designed for efficient, consistent performance - With superior OE technology and know-how, Aisin ensures that every thermostat provides perfect OE form, fit, and function - Manufactured using only the highest quality materials for long life and dependable cooling system performance - Features correct OE specified operating temperature - Gasket included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GNQY7X4 | | Backlight | No | | Best Sellers Rank | 887,898 in Automotive ( See Top 100 in Automotive ) 64,164 in Car Engine & Engine Parts | | Brand | AISIN | | Brand Name | AISIN | | Colour | Factory | | Connectivity Protocol | Wired | | Connectivity Technology | Wired | | Control Method | Touch | | Control Type | Button Control | | Controller Type | touch | | Controller type | touch | | Customer Reviews | 4.6 out of 5 stars 538 Reviews | | Display Type | digital | | Global Trade Identification Number | 04954514965101 | | Included Components | thermostat | | Item Shape | cylindrical | | Item Type Name | Aisin THT-019 OE Engine Coolant Thermostat | | Manufacturer | AISIN | | Manufacturer Part Number | THT-019 | | Material Type | Plastic | | Model Name | AISIN | | Model Number | THT-019 | | Model name | AISIN | | Mounting Type | Wall Mount | | Power Source | Corded Electric | | Product Style | Classic | | Specific Uses For Product | [POSSIBLE USES: Engine temperature regulation, Vehicle heating and cooling system control, Automotive cooling system maintenance] | | Specific uses for product | [POSSIBLE USES: Engine temperature regulation, Vehicle heating and cooling system control, Automotive cooling system maintenance] Specific uses for product [POSSIBLE USES: Engine temperature regulation, Vehicle heating and cooling system control, Automotive cooling system maintenance] See more | | Temperature Control Type | automatic | | Unit Count | 1.0 count | | Voltage | 12 Volts | ## Product Details - **Brand:** AISIN - **Colour:** Factory - **Connectivity technology:** Wired - **Controller type:** touch - **Included components:** thermostat - **Model name:** AISIN - **Power source:** Corded Electric - **Temperature Control Type:** automatic - **Voltage:** 12 Volts ## Images ![AISIN THT-019 OE Engine Coolant Thermostat - Image 1](https://m.media-amazon.com/images/I/71hjMs76KHL.jpg) ![AISIN THT-019 OE Engine Coolant Thermostat - Image 2](https://m.media-amazon.com/images/I/71A5l1ICI2L.jpg) ![AISIN THT-019 OE Engine Coolant Thermostat - Image 3](https://m.media-amazon.com/images/I/71pxzwT+jKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Aisin or nothing *by M***R on 21 February 2026* Delivered on time and is to OE standard for those of you who don’t know, Aisin, is the OE manufacturer for Toyota when it comes to water pumps and thermostats.
