Skip the fuel injection cleaning unless they can show you actual carbon buildup with a borescope. That one is almost always a padding item. Focus budget on fluids, belts, and a thorough inspection of the cooling system instead.

Coolant flush is genuinely needed at this mileage, not a upsell. Degraded coolant loses its corrosion inhibitors and starts attacking the water pump and radiator from the inside quietly.

Serpentine belt and tensioner should be done together at 150k. Replacing the belt alone and leaving an old tensioner is a half job that usually comes back to bite you within a year.

Water pump on the 3.6 Pentastar is a known weak point around this mileage. If it hasn't been replaced yet ask them to inspect it closely, a preventive swap is far cheaper than a roadside failure.

Transfer case and diff fluids at 150k are not optional, they're overdue. Most owners skip them until something whines and by then the damage is already done.

My 2018 Wrangler Sahara is about to hit 150,000 kilometers and I want to be proactive instead of waiting for something to break. I've been pretty good with oil changes but I know there's a bunch of stuff that usually gets ignored like the transfer case fluid, serpentine belt, and maybe even the coolant. The thing is, I don't fully trust myself to know what actually needs attention at this mileage versus what shops just add to pad the bill. I've heard that going to Jeep Service Experts Musaffah is a good move because they see these high-mileage JKs every day and know exactly which components tend to wear out first on the 3.6 engine. I'm planning to take it in next week for a full inspection and just wanted some advice from owners who've been through the 150k mark already. What actually failed on yours around this mileage? Was it water pump, alternator, maybe the radiator? Trying to budget ahead and also avoid getting talked into stuff like "fuel injection cleaning" that might be useless. Really appreciate any real-world experiences before I hand over my keys.
