When your Dodge Charger 3.6 starts overheating, it’s more than just an inconvenience—it’s a signal that something serious might be wrong under the hood. At Greasers Auto, we’ve seen this issue many times, and we’re here to explain what causes it, what the warning signs are, and how we fix it.
What Are Cylinder Heads and Why Do They Warp?
Cylinder heads are an essential part of your engine, sealing the combustion chamber and housing components like valves and spark plugs. They’re typically made of aluminum or cast iron and are designed to withstand high temperatures and pressures.
However, in Arizona’s extreme heat, the risk of cylinder head warping increases significantly if your engine overheats. When this happens:
The seal between the cylinder head and engine block weakens.
Coolant leaks can develop, which leads to further overheating.
Compression loss in the cylinders reduces performance and could lead to engine failure.
Common Causes of Warped Cylinder Heads
In our experience at Greasers Auto, overheating in the Dodge Charger 3.6 due to warped cylinder heads often stems from:
Coolant Leaks: Even small leaks can reduce coolant levels enough to disrupt temperature regulation.
Faulty Thermostat: A malfunctioning thermostat can prevent coolant from circulating properly, causing heat to build up.
Neglected Maintenance: We’ve found that old coolant or skipped system checks can lead to corrosion and blockages in the cooling system.
Blown Head Gasket: This often accompanies warped cylinder heads and further exacerbates overheating issues.
Symptoms of Warped Cylinder Heads
If your Charger is showing any of these signs, warped cylinder heads could be the culprit:
Persistent overheating, even after refilling coolant.
White smoke coming from the exhaust, often a sign of coolant burning in the engine.
Milky or discolored oil, indicating coolant mixing with engine oil.
Loss of engine power or misfiring.
Visible coolant leaks beneath the vehicle.
