2015–2021 Hino 198/ 258 / 268 / 338 / 358 Radiator Without Frame — OEM Design | Direct Fit | 

Looking for the correct OEM radiator for your Hino 258, 268, or 338 truck? Stop wasting time and money on aftermarket designs that don’t fit right! This is the real solution you need 🔥

✅ Why This Radiator is the Best Choice:

• 💪 High Performance & Heavy Duty Design
  Built to endure harsh conditions, towing loads, and daily fleet use.

• 🛠️ Pre-Installed Nuts for Mounting
  Includes factory-threaded mounting nuts already installed, saving you significant labor time and eliminating the hassle of transferring hardware from your old radiator.

• 🛡️ Stainless Steel Oil Cooler (Not Aluminum!)
  Unlike standard aluminum oil coolers that corrode and fail faster, stainless steel offers superior durability, corrosion resistance, and heat efficiency — helping extend engine and transmission life.

• 🔩 OEM Mounting Design (No Frame Needed!)
  Direct replacement for the original radiator. No need to replace the entire frame — just swap the radiator itself.
  Most aftermarket radiators are NOT true OEM design ❌ — they force you to install the complete radiator + frame assembly. This adds cost, labor, and future headaches.

• 📏 Perfect Fit Guaranteed
  Manufactured under IATF 16949 Certified standards, ensuring precision fitment and factory-grade reliability.

• 🧪 TTFT Certified: Thousand Trucks Fitting Test
  Rigorously tested on 1,000+ Hino trucks to guarantee real-world fit and performance.

⚠️ Special Note About 2015 Models:

The 2015 model year was a transition year, so mounting points may vary:

• Early 2015: Bolt mounts are located on the side of the top tank

• Late 2015 and newer: Bolt mounts are located on the top of the top tank

🖼️ Please check your original radiator and our pictures before buying to ensure a perfect match!

🔥 Warranty & Delivery:

• ✅ 1-Year Limited Warranty Included

• ✅ Free Delivery Across the U.S.

⚠️ IMPORTANT – Transmission Oil Cooler Notice:

This radiator includes a built-in stainless steel transmission oil cooler, designed as a completely separate and sealed system from the main coolant circuit.

• 🔌 If your original radiator has a transmission oil cooler, you can directly connect your existing transmission lines.

• 🧯 If your original radiator does NOT have a transmission oil cooler, you can simply leave the cooler ports unconnected — no need to cap or seal them.
  It will NOT leak, since the oil cooler is isolated from the coolant system.

🔧 However, if the transmission oil cooler is loosened, over-tightened, cross-threaded, or otherwise damaged, it will void the warranty.
👉 Please install carefully using correct torque and fittings.

🛠️ Fitment Information:

• ✅ Fits only Hino Diesel Engines (2015–2021 198 / 258 / 268 / 338 / 358)
