The Average Cost of Jeep Wrangler Radiator Replacement

Radiator failure is among the most common issues with the Jeep Wrangler. So, it needs the replacement of the broken component.

Based on several variables, the price of changing the Jeep Wrangler radiator may differ.

The radiator may cost up to $950 on its own, while labor costs around $185 to $250.

Do not panic if you’re unsure about the other factors in estimating the replacement cost. We’ll explain all the details in this article.

When selecting or preparing to change the radiator in the Jeep Wrangler, you should have a detailed understanding of the related expenditures. This article includes every aspect of this replacement task, including expected costs.

Most radiators cost somewhere around $800 to $1000. In addition, the cost of labor is somewhere around $200 to $250. This estimated cost will differ depending on many major factors, such as the radiator’s type, shape, quality of materials, and manufacturer.

Note that the price will differ based on the Jeep’s type, manufacturing year, and desired service provider or region.

When Do You Replace the Radiator in The Jeep Wrangler?

A Jeep is overheating if the heat warning light shows up while driving. Although it does not wear down, it indicates oncoming problems. It is indeed essential to note that it is preferable to identify early damage. Then change it before it creates more problems.

Therefore, replacing the present radiators as early as possible is important. The easiest way to determine if it’s the time to change the radiator is to look for warning signs.

The Warning Signs Are:

The heat indicator would be the very first indication seen. If the heat indicator suddenly displays while you are driving, examine the radiator.

  • Leakage of refrigerant from the Jeep: A refrigerant leakage indicates that it is broken. If the radiator (often bright orange, greenish, or reddish water) is leaking from underneath the Jeep, you have a leakage. The passage should be repaired immediately, whether it is an issue with the radiators, a pipe, or the cylinder block.  
  • The refrigerant in the radiators must be a clear shade of yellow or greenish. Inside the radiator, corroded particles have formed if the refrigerant takes on a reddish or greasy look. These particles may have a great effect on the performance of the radiator.
  • The motor refrigerant could become yellow for a number of reasons. And you must get it inspected as early as possible. 
  • If you frequently add refrigerant to the radiators or if the “short refrigerant” indication continues flashing on the dash, you probably have a leakage. Drive the Jeep to a trustworthy technician for an instant analysis if the refrigerant must be changed soon.

If you see any of these indications in the Jeep Wrangler, you should get it inspected by a professional garage.

Instructions for Replacing the Radiator

Replacement of radiators is a task better left to professionals. As a Jeep driver, you should routinely examine the radiators for corrosion. Or search for the mentioned early symptoms.

Follow these instructions to change the radiators on a Jeep Wrangler.

Necessary Equipment

  • Modern radiator
  • Drainage pans
  • Stand and jacks
  • Socket wrenches

When hurrying to replace a whole radiator, take a moment to assess the entire refringent system. Check the top cap (or overflowing cap) for leakage.

Inspect the harnesses and pipes for rust, fractures, and leakage. Inspect the fan clutches joints between both the radiators and the hydraulic pump engine.

Don’t forget to inspect the engine’s thermostat. If a ventilation issue led the motor to overheat, the thermostat might be damaged. You might want to fix this little component when repairing the radiators. 

Empty the Radiators

Radiators may be emptied in 2 different ways. First, the radiator lid must be removed. To empty the radiator, unscrew the lid. Then either detach the base radiator pipe or use the petcock gate. It is necessary to empty refrigerant into a polymer container.

Separate the Radiator

Once the refrigerant empties, remove the radiator’s pipes, connectors, and mounting screws. 

On the majority of jeeps, you must separate the following parts:

  • Pump radiator pipe
  • The radiator’s top pipe
  • Lower radiator pipe
  • Fan connection
  • Cooling fan screws
  • Air conditioning fan
  • Thermostatic housing
  • Powertrain coolers (Most jeeps need special equipment to detach)
  • 4×4 and Diesel Jeeps have lubricating oil cooler pipes
  • Radiator connection screws
  • Screws for fender installation
  • Fasteners for radiator installation
  • Detach the old radiator

After removing all of the pipes, bolts, and wires, you must be capable of removing the radiators from the Jeep.

Several radiators can be changed by raising the Jeep out of the way, while others should be replaced from underneath.

Install New Radiator

After putting in the new radiator, put back all the components that were taken off. Starting with the radiator installation screws, remove the reservoir pipe.

Add Refrigerant

Ensure that the petcock and all other vents and coverings on the new radiators are closed. When all pipes and screws have been installed, fill the radiators with refrigerant.

Inspect the lubricant and gearbox liquid levels to determine whether they were spilled during the replacement.

Allow Air to Pass

Trapped air in the conditioning system may lead to overheating and a decrease in the heater’s efficiency.

Contact a technician for clear instructions on removing the trapped air since the technique for draining air varies per Jeep.

Keep a record of all pipes, connectors, screws, and other parts because the parts must be reassembled backwards for replacement.


What is the Average Lifespan of a Jeep Radiator?

According to most Jeep experts, a well-serviced radiator will last at least 10 to 12 years. When properly maintained, vintage steel radiators may last the lifetime of the Jeep. However, current radiators are most often constructed of plastics, which deforms as the radiator warms and cools.

Is Repairing a Radiator Useful?

The cost of labor to install a radiator ranges from $250 to $500. Based on the item type and needed retrofitting. Electricians charge somewhere around $50 and $200 hourly. And the hourly rate for HVAC professionals is $100 to $200. Installation of many units reduces labor expenses.

What is the Cost of Installing a New Radiator?

The average price to replace a radiator varies between $1,250 and $3,500. Although certain replacements may be performed with as little as $750 or as much as $850, these costs vary. Most of the radiator replacements cost nearly $2,000 on average.

Will Replacing The Radiator Improve the Performance of the Jeep?

A fast radiator helps the Jeep’s engine create the greatest horsepower without that much of any sudden stoppage. Metal and Copper were often used to construct older radiators. But the most effective replacement radiators are made out of aluminum.

Final Note

The radiator is among the Jeep’s sensitive components that are important to both the jeep’s and driver’s security on the roadway.

Therefore, having a poorly maintained or dysfunctional radiator raises the risk of suffering a problem. Also, the most effective remedy is to change it with a proper radiator at the appropriate time.
