How much does a 2018 Jeep Grand Cherokee radiator replacement cost?

A 2018 Jeep Grand Cherokee radiator replacement typically runs $700 to $1,500 at an independent shop, parts and labor included. The radiator itself is $150 to $600, labor makes up most of the rest, and the job takes 2 to 4 hours.

Why does the price change with the engine?

The 2018 Jeep Grand Cherokee came with more than one engine, and they do not share the same part or the same access. A tighter engine bay or extra teardown adds labor hours, and the part price moves too. Sites that show one national number flatten that out. Pick your engine on the estimate above for a closer figure.

Is it always the radiator when my Jeep overheats?

Not always, but the radiator is one of the most common culprits, which is why it is worth checking first. A clogged, corroded, or leaking radiator causes overheating on its own, and it is also the most common place a car loses coolant. The other leading causes are a stuck thermostat, a failing water pump, a bad cooling fan, and low coolant. Because several of these look identical from the driver's seat, get a real diagnosis before you approve any repair, so you fix the part that actually failed.

Can I drive my Jeep with a bad radiator?

Not for long. A leaking or clogged radiator lets the engine overheat, and driving an overheating Jeep risks a warped cylinder head or a blown head gasket, a $3,000 to $8,000 repair on top of the radiator. If the temperature gauge climbs or you see steam, pull over, let it cool, and keep any driving to short, low-speed trips until it is fixed. If it keeps overheating, tow it.

How long does a radiator last?

Most original radiators last roughly 8 to 12 years or 100,000 to 150,000 miles. The usual failure on modern units is the plastic end tank, which cracks or seeps with age and heat cycles, and internal clogging from old coolant. Regular coolant changes are the cheapest way to extend radiator life.

Are there recalls on the 2018 Jeep Grand Cherokee?

Yes, NHTSA lists 11 recalls for the 2018 Jeep Grand Cherokee. Recall repairs are done free of charge at a franchised dealer for that brand, so it is worth checking your VIN before paying a shop for related work.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE)

Chrysler (FCA US LLC) is recalling certain 2014-2019 Jeep Grand Cherokee vehicles equipped with the 3.0L EcoDiesel engines. The Exhaust Gas Recirculation (EGR) cooler may crack and allow pre-heated vaporized coolant to enter the EGR system. This mixture may combust inside the intake manifold. Combustion in the intake manifold can increase the risk of a fire.

FCA US LLC will notify owners, and dealers will replace the EGR cooler, free of charge. Dealers will also inspect and, as necessary, replace the intake manifold. Parts are not currently available. Owners were mailed an interim notification on December 21, 2021. A second notification will be mailed when parts are available, currently expected to be around March 11, 2021. The recall began March 11, 2021. Owners may contact FCA US LLC customer service at 1-800-853-1403. FCA US LLC's number for this recall is W79.

Real owner report, verbatim from NHTSA:

“The contact owns a 2018 Jeep Grand Cherokee. The contact stated that since the vehicle was purchased, there was an abnormally strong coolant odor coming from the vehicle. The dealer was notified of the failure and informed the contact that the coolant reservoir was recently refilled, and the odor might be due to an overflow. The contact stated that the failure persisted, and the vehicle was taken to the dealer, where the water pump was replaced. The contact stated that the water pump had been replaced approximately nine times under warranty due to the strong coolant odor and a water pump leak; however, the failure persisted. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 125,000.”

Worth knowing: the radiator is one of the most common causes of overheating, alongside the thermostat, water pump, and hoses. Get the real source confirmed before you approve any repair, so you fix the part that actually failed.

Recall fixes are free at the dealer. Everything else deserves a fair price.

How your cooling system works

The radiator is one piece of a loop. Here is how the parts work together, so you understand exactly what your car is doing and why.

Diagram of an engine cooling system showing how coolant flows from the engine through the thermostat and upper hose to the radiator, where the fan cools it, then back through the lower hose and water pump to the engine, for the 2018 Jeep Grand Cherokee radiator — Coolant carries engine heat to the radiator, the fan pulls air through it to shed that heat, and the water pump pushes the cooled coolant back. A leak, a stuck thermostat, or a dead pump all look like “overheating” from the driver’s seat.

Found a puddle? What the color tells you

Bright green

Classic coolant leak. Find the source before it overheats.

Orange / pink

What most modern vehicles use (OAT). Same urgency as green.

Rusty brown

Old, corroded coolant. Overdue for a flush.

Milky / oily

Coolant mixing with oil, like a coffee milkshake. Can mean a head gasket. Serious.

What a radiator replacement is like on the 2018 Jeep Grand Cherokee

The bill splits into three pieces: the radiator itself, the labor to swap it, and one to two gallons of fresh coolant with a fill-and-bleed to clear air pockets. On most vehicles the radiator sits behind the bumper cover, grille, condenser, and fans, so a tech spends two to four hours getting it out and back in. That access time, not the part price, is usually why two quotes for the same job look so different.

The 2018 Jeep Grand Cherokee shipped more than one engine, and the larger one runs a little higher on both parts and access. Ask your shop to confirm the exact part for your engine before the work starts.

Estimate note: these are researched independent-shop ranges, not a guaranteed quote. The only exact number is one from a shop that has seen your car.
