2016 Jeep Wrangler Engine Cover is Burning: Causes and Fixes
Reading Time: 7 minutes Many 2016 Jeep Wrangler owners have noticed an unusual problem: the engine cover is burning or melting. This issue can be stressful and confusing, especially for new Jeep drivers. If you open your hood and see burn marks, melting plastic, or smell something strange, you may be facing this problem. Understanding why it happens, how serious it is, and what steps you should take is important for your safety and your Jeep’s health. In this article, we’ll break down the causes, warning signs, solutions, and prevention tips in clear, simple terms.
Why Is The 2016 Jeep Wrangler Engine Cover Burning?
The engine cover, usually made from plastic or composite material, sits on top of the engine. Its main job is to keep dust out and reduce engine noise. When it starts to burn or melt, it means something is making it much hotter than normal.
Common Causes
1. Excessive Engine Heat
If the engine is running hotter than normal, the cover can start to melt or burn. This can happen if the cooling system isn’t working well.
2. Exhaust Leaks
If exhaust gases escape near the engine cover, they can make the area much hotter and burn the cover.
3. Faulty Engine Components
Broken or worn-out parts like the manifold, heat shields, or gaskets can direct extra heat toward the cover.
4. Aftermarket Modifications
Adding non-original engine parts or changing the exhaust can change how heat moves under the hood.
5. Poor Material Quality
Some engine covers are made from materials that cannot handle high temperatures for long periods.
Signs Your Engine Cover Is Burning
Spotting the problem early can help you avoid bigger damage. Look for these signs:
- Burning Smell: A strong, plastic-like smell coming from the engine bay.
- Visible Melting or Warping: The cover looks deformed or has melted spots.
- Smoke: Smoke may come out when you open the hood.
- Discoloration: Parts of the cover may look darker or different in color.
- Check Engine Light: Sometimes, heat damage triggers warning lights.
How Serious Is A Burning Engine Cover?
A burning or melting engine cover is a safety hazard. Here’s why:
- Fire Risk: Melting plastic can catch fire if the temperature gets high enough.
- Engine Damage: Overheating can damage other engine parts.
- Toxic Fumes: Burning plastic releases unhealthy fumes that can get inside your Jeep.
If you notice any of the warning signs, act quickly to avoid further problems.
What To Do If Your Engine Cover Is Burning
Here’s what you should do step by step:
1. Turn Off The Engine
Stop your Jeep and let the engine cool.
2. Open The Hood Safely
Wait for at least 20-30 minutes before opening the hood. Hot parts can burn you.
3. Check For Damage
Look for melted spots, burnt wires, or smoke.
4. Do Not Drive
If the cover is badly burned, do not drive the Jeep until you fix the issue.
5. Contact A Mechanic
Call a trusted mechanic or take your Jeep to a service center for inspection.
Example Scenario
If you smell burning plastic right after a long drive, stop your Jeep, wait for it to cool, and check under the hood. If the cover looks melted, call for help instead of trying to drive home.
Main Engine Components And Heat Sources
Knowing which parts cause the most heat helps you understand why burning happens.
| Part | Function | Heat Risk |
|---|---|---|
| Exhaust Manifold | Carries exhaust gases away | Very High |
| Catalytic Converter | Cleans exhaust gases | High |
| Engine Block | Houses moving engine parts | Medium |
| Plastic Engine Cover | Protects engine, reduces noise | Low (should stay cool) |
If hot exhaust parts are too close to the engine cover or their shields are missing, heat can transfer and cause burning.
How To Prevent Engine Cover Burning
There are several ways to reduce the risk and keep your 2016 Jeep Wrangler safe:
- Regular Maintenance: Check coolant levels, hoses, and fans.
- Inspect Heat Shields: Make sure all heat shields are present and not loose.
- Avoid Cheap Engine Covers: Use original or high-quality aftermarket covers.
- Check for Leaks: Have a mechanic check for exhaust leaks.
- Don’t Overload the Engine: Avoid pushing your Jeep too hard, especially in hot weather.
Extra Tip
If you install aftermarket parts, ask the installer if they affect engine heat. Sometimes, bigger exhaust pipes or turbo kits can change airflow and increase temperatures.

Two Insights Many Beginners Miss
1. Small Leaks Cause Big Problems
Even a tiny exhaust leak near the engine cover can create enough heat to melt plastic. Most beginners look for big damage, but small leaks are easier to miss and just as dangerous.
2. Aftermarket Parts May Void Warranty
If you install non-Jeep engine covers or heat shields, your warranty might not cover heat damage. Always check with your dealer before making changes.
When To Call A Professional
Not every repair is DIY-friendly. Call a professional if:
- The engine cover keeps melting after replacement.
- You smell burning plastic but can’t find the source.
- The check engine light stays on.
- There’s smoke from under the hood.
Certified Jeep mechanics have the right tools to test for exhaust leaks and overheating.
Is It Safe To Drive With A Burned Engine Cover?
It’s not recommended. Here’s why:
- Fire Hazard: Melting plastic can drip onto hot engine parts.
- Inhalation Risk: Burning plastic fumes are dangerous.
- Worsening Damage: The longer you drive, the more likely other engine parts get damaged.
If you must drive, do so only to the nearest repair shop and avoid long trips.
