⚠️ IMPORTANT – Transmission Oil Cooler Notice:
This radiator includes a built-in stainless steel transmission oil cooler, which functions as a separate sealed system from the engine coolant.
-
🔌 If your truck has transmission cooler lines, simply plug them in — it’s ready to go.
-
🧯 If your truck does not use a transmission cooler, you can leave the ports unconnected — they will NOT leak.
🔧 Warranty Warning:
If the transmission oil cooler is damaged during installation (from over-tightening, cross-threading, or stripping), the warranty will be void.
👉 Use correct torque and installation technique to preserve coverage.
