5 Signs Of A Blown Head Gasket Jeep Wrangle (5 Causes)

Blown head gaskets are conventional issues, especially with aging vehicles. However, this issue doesn’t exempt stylish trucks like the Jeep Wrangler.

The symptoms of blown heads start subtly that you never really know or put more thought into the case.

This article will help you comprehend the signs of this faulty gasket to keep you better prepared.

A head gasket failure indications usually start with overheating since there is a coolant escape. You will lose coolant but won’t notice these leakages, and the leak causes bubbling, which shouldn’t be so. In advanced situations, lots of white smoke emerges in contrast to the regular amount, and your car may not ignite anymore or even run slowly.

Signs of a Blown Head Gasket in Jeep Wrangler

Several factors indicate a blown head gasket in your jeep wrangler.

While some are peculiar to a blown gasket, others also serve as indicators for other problems, but if you are discerning, you can identify these signs when your head gasket is blown.

Here are some signs you’ll notice when your head gasket blows;

#1. Boiling Coolant

The primary function of a head gasket is to shut the combustion cycle, making it simple to detect a gasket leak from pressurized oxygen since it is an obvious sign.

When a car motor loses its combustion strain, the oxygen from it enters the radiator resulting in bubbles.

An escape in the combustion gas makes it look like heat influences the boiling since air is always available at the bottom.

Additionally, a Rev transcription test would be ideal for verifying doubts about compression leaks.

You can have someone press the accelerator pedal while inspecting if the aerated coolants pour out from the receptacle.

If the coolant pours out, you have a blown wrangler head gasket way past the early stages.

#2. Excess white fumes

Coming to your car’s rear, another conventional sign of a faulty head gasket in Jeeps is a particular white smoke emission.

This problem results from only fluids like coolants entering the combustion room.

But do not mistake this smoke with the typical fumes you sometimes notice, as it happens occasionally.

White smokes often emerge from your exhaust pipes due to condensation, but it differs from excessive gas.

You can also ascertain this by inspecting the emissions from your exhaust pipe when you press the gas pedal.

#3. Loss in coolant without traces

Experiencing coolant loss makes it effortless to detect a blown head gasket on time before complications arise.

Leaks in gaskets allow fluids to enter the combustion area, resulting in coolant burning without evident leakages.

When this happens, you’re sure to experience overheating in your engine, so check your coolant level to detect early problems.

In addition, you can check the engine light to discover when you need a coolant refill or your radiator.

#4. Engine misfire and black coolant

A prominent sign contrasts the regular coolant loss with other reasons: pollution with ignition leftovers.

The burning of gases with fumes goes upwards, leaving the coolant container bubbling but with a color alteration in the coolants, resulting in Jeep Wranglers with blown gaskets.

#5. Fluid Contamination

A clutter of motor fluids is a clear indication of head gasket failure.

Every vehicle has various fluids required to function smoothly, but they need a head gasket cylinder to go to their respective chambers.

Head gaskets possess diverse gaps around their body that allow fluids to flow to their specific areas.

But when a head gasket cylinder cracks in its hole areas, many engine problems arise as the liquids won’t go to their unique chamber but blend with others.

Unfortunately, most head gasket leaks are so subtle that you don’t notice and keep on driving with them. 

Notwithstanding, it isn’t advisable to drive with blown head gaskets because these minor challenges lead to enormous complications, particularly if unlikely liquids combine.

If the problem advances, you may need to replace head gaskets or engines in worse situations. 

You’ll only need to repair head gaskets if you detect the issue on time, reducing the cost of expenses.

Replacement of head gaskets costs around $1200 to $3000, while repairing head gaskets cost lesser as sealers are used.

Causes of Blown Head Gasket

#1. Improper Installation

Adding a new head gasket to an engine enhances the possibility of gasket issues as you can confuse some components for another.

In addition, making mistakes in the installation process makes it impossible for liquids to flow appropriately into their specific areas, resulting in leakages.

#2. Thermostat stuck shut

Thermostats are tiny components in cooling systems that monitor the discharge of coolants and how it continuously circulates into the heater to remove accumulated heat.

A faulty thermostat won’t efficiently manage, and when it has amassed large volumes of debris, there are high chance of generating heat leading to gasket damage.

#3. Faulty radiators or fans

Bad radiators lead to gasket problems and are as severe as a reduced coolant cycle.

An inefficient radiator eliminates a coolant’s cooling period, making them flow to chambers still hot, maximizing the strain on an engine.

This problem results in failed gaskets and a burning smell coming from the cooling system.

#4. Dirty Engine oil

Many car owners only understand motor oil as a lubricant for moving car components, but it also serves as an engine coolant.

Using engine oil on moving metal parts eliminates friction resulting from metal parts in proximity and reduces temperature.

The absence of lubricants causes engine overheating, and using dirty motor oil serves no purpose leading to gasket failures in advanced situations.

#5. Engine misfires

Engine misfires happen when engine block cylinders don’t generate power and can severely affect an engine’s inner parts.

Allowing these inefficient engine block cylinders to continue without fixing the issue results in extreme damage to motors.

A preferable alternative is to analyze your engines frequently to ensure everything’s working fine.

Conclusion

Head gaskets are crucial links that connect cylinders and engine blocks, so damages will negatively impact the Jeep Wrangler.

Keep an eye out for indications of wrangler blown head and maintain your truck to avoid such complications as they are expensive.

Remember, there is a limit where repairs will serve no purpose, so ensure to choose the right solution.
