I bench tested it with a heat gun before installing and it functioned flawlessly. Smooth install and is working great after a couple months. Wire terminals plugged right in to the existing wire harness. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great *by E***C on Reviewed in the United States on March 8, 2019* Perfect fit but you’ll need tread tape --- ## 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.vu/products/72629876-spi-at-01377-thermal-fan-switch-for-polaris-replaces-oem](https://www.desertcart.vu/products/72629876-spi-at-01377-thermal-fan-switch-for-polaris-replaces-oem) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
