Silicone Hose Kit for Jeep Grand Cherokee (2012-2018) 6.4L

Heavy-Duty Silicone Hose Kit for 2012-2018 Jeep Grand Cherokee

What it Does: The Silicone Hose Kit replaces the failure-prone factory rubber coolant lines on the 2012-2018 Jeep Grand Cherokee to eliminate leaks, prevent thermal hose collapse, and sustain cooling efficiency under high mechanical stress.

The Stock Jeep Grand Cherokee WK2 Cooling Vulnerability

Under the high-temp operating conditions generated by the naturally aspirated 6.4L HEMI 392, factory EPDM rubber coolant hoses experience accelerated heat-aging. Repeated thermal cycling causes standard rubber to harden, bake brittle, and micro-fracture along critical bend radiuses. Furthermore, exposure to under-hood petrochemicals and persistent electrochemical degradation (ECD) breaks down the internal reinforcement layers over time, creating internal bore softening, localized swelling, and catastrophic high-pressure ruptures when the cooling circuit pressurizes under load.

The Engineering Solution

Constructed with multi-ply reinforced high-grade silicone, this cooling upgrade withstands sustained operating temperatures ranging from -65°F to 500°F without hardening or blistering. The reinforced woven ply fabric delivers significantly elevated burst pressure ratings compared to factory hoses, preventing high-rpm ballooning or suction-side collapsing. A low-friction, micro-smooth internal bore reduces hydrodynamic drag across the entire radiator circuit, sustaining peak fluid flow velocity. Molded to exact OEM geometries, each hose seats securely on factory coolant junctions and water neck outlets without kinking.

Frequently Asked Questions

Does this fit the WK2 Grand Cherokee?
Yes, this is a direct fit for the 2012-2018 Jeep Grand Cherokee equipped with the 6.4L HEMI engine.

Can I reuse my factory constant-tension spring clamps?
While OEM spring clamps can work if sized properly, lined worm-drive or T-bolt clamps are strongly recommended to prevent cutting into the exterior silicone jacket.

The Jeep Durability Benchmark

Built for the heavy thermodynamic demands of performance towing and aggressive driving, this cooling upgrade delivers zero-failure hydraulic integrity and long-term thermal endurance in demanding environments.
