Review: Fits perfect on my Cadillac xt5 - The thermostat housing worked great on our xt5 cadillac. Much cheaper than the auto parts stores by a long shot. Great material easy to install and bolted up perfectly Review: Better than OEM in my opinion. And priced right. - I looked through the reviews before I ordered. I had a suspicion that the 1 star reviews were Inaccurate at best. Here is my Experianced. The thermostat and housing assembly was packaged so it would not be damaged from Shipping. It was an exact copy of the defective old OEM thermostat that was removed. The bolts supplied with the assembly were just 2mm shorter than what was removed. All went well with the installation. I did swap the o ring over to the old coolant pipe so it wouldn’t require the injectors to be removed. The operating temp now is 200-205 which is spec. No leaks no runs and no errors.

Master Auto tech. ### ⭐⭐⭐⭐⭐ 5 stars… for now *by T***R on August 19, 2025* This looks to be made of some lower quality metal than the original but the price was right and as an added bonus it appears to work just fine. Tolerances were perfect allowing it to mate up to the existing coolant pipe so I didn’t have to remove the fuel rails. The o-ring included on the mitzone pipe was great quality and fit perfectly on the GM pipe I left in the valley. Like everyone else says the bolts are too long but I just used the OE bolts to put it back in. Pretty happy with my repair so far, if it fails I’ll come back and change this review. ## Frequently Bought Together - MITZONE Coolant Thermostat Housing Assembly compatible with 2017-2023 Buick Cadillac Chevy GMC Vehicles - LaCrosse Regal XT5 XT6 Blazer Acadia 3.6L Replace - ACDelco GM Original Equipment 12650595 Engine Coolant Temperature Sensor, Black - GM Genuine Parts 12648665 Engine Intake Manifold Seal --- ## 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.tn/products/587716691-mitzone-coolant-thermostat-housing-assembly-compatible-with-2017-2023-buick](https://www.desertcart.tn/products/587716691-mitzone-coolant-thermostat-housing-assembly-compatible-with-2017-2023-buick) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-07*
