The #1 Sign Your Subaru’s Head Gasket is About to Fail
Subaru owners love their cars for their reliability, all-wheel drive performance, and long-lasting engines. However, one issue that has garnered attention over the years is head gasket failure. While not every Subaru will face this problem, it’s prevalent enough that owners should be vigilant about early warning signs to prevent costly repairs.
The Biggest Red Flag: Overheating
The primary indicator that your Subaru’s head gasket may be failing is engine overheating. If your temperature gauge consistently moves into the red zone or you notice steam emanating from under the hood, it’s crucial to address the issue promptly. Overheating often signifies a minor head gasket leak that could escalate if neglected.
A failing head gasket can allow coolant to seep into the combustion chamber or oil passages, disrupting the engine’s temperature regulation and leading to recurrent overheating. Ignoring these signs can result in severe engine damage, such as warped cylinder heads or a completely blown head gasket.
Other Symptoms of a Failing Head Gasket
In addition to overheating, be attentive to the following signs:
- Unexplained Coolant Loss: If your coolant levels drop without visible leaks, it might be leaking internally due to a compromised head gasket.
- White Exhaust Smoke: Thick white smoke with a sweet scent indicates coolant burning within the engine.
- Bubbling in Radiator or Coolant Reservoir: Combustion gases leaking into the cooling system can cause bubbling in these areas.
- Milky Oil Appearance: A mixture of coolant and oil results in a milky, frothy substance on the oil cap or dipstick.
- Reduced Engine Performance: Misfires, rough idling, or a general loss of power can stem from coolant entering the cylinders.
