Engine oil steadily goes up to 180 and stays there. I was skeptical of this item, but it has worked flawlessly for my sbc 350 oil cooler setup. Review: Quick warm up but not brass fittings, PLASTIC!!! - The add says that I t comes with brass fittings, it comes with 1/2” NPT to 1/2” BARB plastic. I’m not going to use plastic fittings on my 4L80E transmission. I have around $3000.00 and I refuse to use plastic fittings. I ordered BRASS Fittings. Some people think cool fluid is the best way to go. Transmission fluid is meant to be warm and some people even eliminate the stock cooler and the transmission runs cold. Transmissions need to run 200° easy. I’m using it on my 1997 GMC Sonoma and I don’t want the transmission to be too cool. Some people think the cooler the better but I’m not one of them. ## Features - Bypasses cooler at 180 degree farenheit - Provides quicker warm-up temperatures - Perfect for cold weather climates - Can be rotated 180 degree to switch flow direction ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004XONTNO | | Best Sellers Rank | #296,641 in Automotive ( See Top 100 in Automotive ) #533 in Automotive Replacement Engine Thermostats | | Brand | Derale | | Customer Reviews | 4.4 4.4 out of 5 stars (33) | | Date First Available | April 20, 2011 | | Exterior | Painted | | Item Weight | 1.6 ounces | | Item model number | 15719 | | Manufacturer | Derale | | Manufacturer Part Number | 15719 | | Mirror Adjustment | Button Control | | Model | Fluid Control Thermostat Kit (1/2" NPT) | | OEM Part Number | 15719 | | Product Dimensions | 4.38 x 7 x 2.25 inches | | Voltage | 230 Volts | ## Images ![Derale 15719 Fluid Control Thermostat Kit - Image 1](https://m.media-amazon.com/images/I/51rAryAQWPL.jpg) ![Derale 15719 Fluid Control Thermostat Kit - Image 2](https://m.media-amazon.com/images/I/41m3bAS2y9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as intended *by M***L on May 17, 2024* Item went in between my engine oil cooler and engine. Engine oil steadily goes up to 180 and stays there. I was skeptical of this item, but it has worked flawlessly for my sbc 350 oil cooler setup. ### ⭐⭐⭐⭐⭐ Quick warm up but not brass fittings, PLASTIC!!! *by G***! on April 8, 2021* The add says that I t comes with brass fittings, it comes with 1/2” NPT to 1/2” BARB plastic. I’m not going to use plastic fittings on my 4L80E transmission. I have around $3000.00 and I refuse to use plastic fittings. I ordered BRASS Fittings.

Some people think the cooler the better but I’m not one of them. ### ⭐⭐⭐ Not opening at rated temperature *by J***S on October 10, 2023* I installed this on a Rotax 9 series engine and after testing found that it was opening at 155F NOT the advertised 180F... My issue is low oil temperatures and long warm up times to get to the minimum 120F operating temp. I wouldn't recommend this product for Rotax 9 series installations. ## Frequently Bought Together - Derale 15719 Fluid Control Thermostat Kit - EVIL ENERGY 3/8" Transmission Oil Cooler Hose 10FT 250PSI SAE J1532 - Derale 13614 Series 9000 Plate and Fin Transmission Oil Cooler,Black --- ## 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.dk/products/12605837-derale-15719-fluid-control-thermostat-kit](https://www.desertcart.dk/products/12605837-derale-15719-fluid-control-thermostat-kit) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-18*
