Radiator Perimeter Seal for Toyota Cooling System 🔧

This OEM-quality radiator seal restores the tight air gap around the core, guiding fresh air through the fins instead of around them. It cushions the radiator against the upper support, reduces vibration, and keeps dirt splash off the core. A proper seal means stable coolant temps, quieter operation, and longer radiator life. Perfect fit for Toyota SUVs and built to handle heat, dust, and off‑road use. 🚗

Why you need it ❄️

Without a healthy radiator seal, the fan and vehicle speed can’t push enough air through the core. Hot air recirculates in the engine bay, A/C efficiency drops, and the cooling system works harder than it should.

How it works 🧊

The molded foam/rubber barrier sits between the radiator, shroud, and upper support. It channels airflow through the fins, stabilizes the radiator, and isolates it from micro-movements that can stress plastic tanks and solder joints.

What happens if it’s broken 🔥

Expect temperature spikes at idle or in traffic, louder fan noise, warmer A/C at stops, and more debris clogging the fins. Long term, heat soak can warp shrouds, weaken tanks, and shorten radiator and hose life.

Fitment and install tips ✅

Replace when brittle, torn, or flattened. Clean mating surfaces, align clips/tabs, and don’t stretch the seal. Best results when paired with intact shroud fasteners.
