I have an Oldsmobile Bravada (GM)** A: I made it work. You are gonna need to know the size of hole and thread size of your water outlet/thermostat housing and then see if the switch/sensor matches those dimensions. I have an 1983 K20 that I installed a dual fan assembly from a dodge charger into and wired up this control to my trucks thermostat housing's temperature switch. Yours is probably different and will require some homework to wire it up--hint: hotrod forums are great for research. **Q: how long in warranty last.mine has stop working** A: Idh **Q: Does this have a hi and low modes or just on and off?** A: Just one setting. I used it for about two months with a dual fan setup but kept having issues so I built a relay pack. **Q: Whats the thread size of the probe?** A: 1/8 pipe (1/8 NPT) ## Frequently Bought Together - Hayden 3651 Universal Add-On Adjustable Thermostatic Fan Control Kit, Custom Fitting & Wiring Required - Hayden 3690 Rapid-Cool™ Reversable Universal-Fit Add-On Fan Kit – Not OEM Replacement - Fan Mounting Kit, Mellbree 2-Pack Electric Radiator Fan Mounting Kit Compatible for Electric Cooling Fan and Transmission Cooler --- ## 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.pt/products/2812858-hayden-3651-universal-add-on-adjustable-thermostatic-fan-control-kit](https://www.desertcart.pt/products/2812858-hayden-3651-universal-add-on-adjustable-thermostatic-fan-control-kit) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-30*
