What does the coolant light on my Jeep dashboard mean?

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

Is an antifreeze leak dangerous?

Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.

Do Jeep Wrangler radiators need to be cleaned?

It could be a good idea to have your Jeep Wrangler radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

Why is my Wrangler overheating?

Your Jeep Wrangler engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

Why does the radiator in my Wrangler sound like it’s rumbling or boiling?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Wrangler. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Is rust in my Wrangler radiator bad?

Yes. Having rust in your Jeep Wrangler radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

When to Service Your 1991 Jeep Wrangler Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Jeep Wrangler radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 1991 Jeep Wrangler is crucial to keep your engine in the best possible shape for years to come. Jeep recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. Your radiator could be close to causing an engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Jeep Wrangler Coolant Fluid Exchange

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Jeep Wrangler’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1991 Jeep Wrangler engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the heater core to the radiator cap, we’re here to give your 1991 Jeep Wrangler the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
