Jeep Wrangler TJ Radiator Hoses

Upper and lower radiator hoses for Wrangler JL/JK or Grand Cherokee WK2 typically cost R450-R950 each depending on OEM versus aftermarket. A full cooling system hose replacement including smaller bypass hoses runs R1,800-R3,200 for parts. Labour adds R800-R1,500 at most Joburg or Cape Town workshops.

Replace, don't repair—temporary tape or sealant fixes rarely last more than a few days. Radiator hoses on Jeeps (especially 3.6L Pentastar engines) operate under high pressure and temperature, so patched hoses will fail again. Quality replacement hoses last 80,000-120,000km under South African conditions.

Silicone hoses handle extreme temperatures better and last longer—ideal for modified Wranglers or Grand Cherokees used for serious off-roading. They cost R1,200-R2,500 per hose (double OEM rubber prices) but withstand Kalahari heat and mountain altitude better. Stock rubber hoses are perfectly adequate for standard Cherokee or Compass models.

Inspect hoses every 40,000km and replace every 80,000-100,000km as preventive maintenance, especially on older Wrangler JK or Grand Cherokee WK models. South African heat, dust, and rough roads age hoses faster than overseas markets. Replace immediately if you see cracks, bulges, or soft spots regardless of mileage.

No—each Jeep model has specific hose shapes and diameters. Wrangler JL hoses differ from JK, and Grand Cherokee WK2 uses different hoses than Cherokee KL, even though both may have the 3.6L Pentastar engine. Always verify fitment by VIN or engine code when ordering to avoid costly returns.
