Not a pressure relief lever style **Q: Is this a pressure tank or just a reservoir?** A: I am unsure, I used mine for a reservoir. It could work as a pressure tank as long as the pressure doesn't become greater than the cap **Q: Does this take standard radiator pressure caps?** A: This is smaller than a standard size cap **Q: Does this tank have a mounting bracket on both sides? The pics only show one side of the tank.** A: No, and yes. This tank comes with a bracket on both sides but due to aftermarket quality control it didn’t fit absolutely perfect. I modified with another bracket I had on hand due to being a Nissan tech and everything fits beautifully. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buen producto *by E***R on 9 September 2025* Excelente ### ⭐⭐⭐⭐⭐ It's okay..could be better.. *by J***E on 23 April 2020* Wish the mounting bracket was two wings or easier to modify to get it mounted and I wish it had a viewing hose or window to show fluid level. ### ⭐⭐⭐⭐ Good *by M***S on 1 July 2026* Great looking ## Frequently Bought Together - RYANSTAR Universal 2L Water Coolant Expansion Overflow Water Tank Reservoir Complete Header kit Aluminium Alloy Silver (Polished) - EVIL ENERGY 10AN Male Weld on Bung Fitting Aluminum 2PCS --- ## 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.jp/products/256807554-ryanstar-universal-2l-water-coolant-expansion-overflow-water-tank-reservoir](https://www.desertcart.jp/products/256807554-ryanstar-universal-2l-water-coolant-expansion-overflow-water-tank-reservoir) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-12*
