Thank you. ### ⭐⭐⭐⭐⭐ worked as expected *by P***R on December 28, 2024* Good fitment does not leak ### ⭐⭐⭐⭐ Mostly good, long term durability in question *by J***. on May 17, 2025* Fits well where it should, but the hose barbs are not metal reinforced like the OEM coolant reservoir. Time will tell whether the unit will leak or crack where the barb meets the tank. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/616839527-1645000049-engine-coolant-reservoir-tank-w-sensor-and-cap-compatible](https://www.desertcart.tn/products/616839527-1645000049-engine-coolant-reservoir-tank-w-sensor-and-cap-compatible) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-25*
