That cooler was prone to rust (yeah, who ever heard of a metal oil cooler) and leakage. With some new 90 degree 6AN fittings and some Oetiler 18.5mm clamps the upgrade was ready to imstall. I cut away the front portion of the lower channel (1-2 inches) to facilitate installation. I used a 12 gauge AL plate to support the lower mounting hole. The AL piece actuallu sinks additional heat from the cooler. Excellent in every way. The cooler fits perefect between the condenser/cooler and the side channel. 2000 Silverado 2500 4WD, extended cab. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Clean the brass flares before install *by B***H on Reviewed in the United States on March 30, 2024* This is an effective cooler for power steering fluid. I have it mounted in the front below my transmission cooler and while sitting at idle, it cools my power steering fluid by 30+ degrees measured from the inlet/outlet at the cooler.The cooler did leak initially. When I inspected it prior to install, there was some overspray from whatever black coating they use and it had spots all over the brass flare. I did not think it would be an issue, so I installed it. After a short test drive it was leaking at the fittings. I removed it, cleaned the overspray with some xylene and then reinstalled with no leaks after. Take the time to inspect and clean if needed and save yourself the additional time having to redo it. Otherwise, I am happy with this cooler and it seems to cool better than the heatsink style cooler I had before. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars So far so good *by S***. on Reviewed in the United States on December 4, 2021* It felt flimsy and with some bad reviews I almost decided against it. Due to orm cost I opted to chance it. Install was relatively straightforward once I got the front end off my truck. So far it is working out. I used stainless braided lines to connect it up and to limit abrasion. --- ## 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.ph/products/12017820-13221-frame-rail-fluid-cooler-black](https://www.desertcart.ph/products/12017820-13221-frame-rail-fluid-cooler-black) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-09*
