Jeep Wrangler JK Radiators

Radiators for Wrangler JL (2018+) with the 3.6L Pentastar V6 typically range R3,500-R6,500 depending on whether you choose aftermarket or OEM. The 2.0L Hurricane Turbo models may run slightly higher at R4,200-R7,200 due to integrated charge air cooling. Prices include core but not fitting—expect another R800-R1,500 labour at most Joburg workshops.

No, Wrangler JK (2007-2018) and TJ (1997-2006) radiators are completely different due to engine bay redesigns and mounting points. The TJ uses the classic 4.0L AMC I6 with a smaller radiator, while JK models use the 3.6L or 3.8L V6 with larger cooling requirements. Always match your exact model year and engine code.

Yes, Grand Cherokee models with the 2.8L CRD or 3.0L EcoDiesel require specific radiators designed for diesel operating temperatures and often include integrated transmission coolers. These units cost R5,800-R9,500 and are not interchangeable with petrol V6 radiators. The WK2 diesel radiator is particularly prone to corrosion in coastal Cape Town humidity.

Radiators don't have a fixed service interval—they last until they fail, typically 8-12 years under normal conditions. South African conditions accelerate failure: UV exposure cracks plastic tanks, gravel roads cause impact damage, and poor coolant maintenance corrodes aluminium cores. Cherokee KL and Compass models with the 2.4L Tigershark often see radiator issues around 120,000-150,000 km.

Yes, full-aluminium aftermarket radiators (R6,500-R11,000) offer better cooling for heavily modified Wranglers or serious off-roaders tackling Mpumalanga trails. They're particularly beneficial if you've lifted your JK/JL, added larger tyres, or frequently use low-range gearing that increases engine load. Standard radiators are adequate for stock Grand Cherokee and Cherokee models in normal use.
