Wont get hot enough in upper radiator hoseDoes not turn on when installed in radiator Hose assembly , never gets hot enough.installed in a inline radiator hose inlet. but unit dose no get hot enough, try to go to a cooler temp sensor.OBDii reading said engine temp had to get to 215f before sensor turned on fan. probably would work if installed in head or radiator itself. I will try going to a cooler temp sensor like a 170deg.tested with heat gun and than unit did turn on fan. so it just wont get hot enough in upper radiator hose. --- ## 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.vn/products/32284213-ground-thermostat-switch-electric-radiator-cooling-fan-coolant-temperature-sender](https://www.desertcart.vn/products/32284213-ground-thermostat-switch-electric-radiator-cooling-fan-coolant-temperature-sender) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
