![]() ![]() A significant variation in compression values between cylinders could indicate a blown head gasket.Ī final diagnostic tool is the coolant system pressure test. Crank the engine and record the compression reading for each cylinder.Then, remove all spark plugs and connect the compression gauge to each cylinder, one at a time.First, disconnect the fuel pump and ignition coils to prevent the engine from starting.To perform this test, you’ll need a compression gauge. Compression TestĪ compression test is essential to diagnose a blown head gasket. Keep an eye out for white or milky residue in the oil, indicating that coolant has mixed with it. Internal leaks may also be present, such as coolant in the oil or vice versa. Look for signs of oil and coolant leaks around the head gasket. Monitoring your Vibe’s exhaust for abnormal smoke is a good way to detect a potential head gasket issue.ĭiagnosis of Blown Head Gasket Visual Inspectionīegin by conducting a visual inspection of your Pontiac Vibe’s engine. When the head gasket fails, coolant can mix with the gasoline, causing it to burn and create the white smoke. White SmokeĪnother symptom of a blown head gasket is the presence of white or gray smoke coming from the tailpipe constantly. The engine is designed to maintain a high pressure level inside the cylinders, so when the head gasket fails, it can interfere with this balance and adversely affect performance. You may notice a rough idle or the engine misfiring due to the head gasket failing between two combustion chambers. Poor Engine PerformanceĪ blown head gasket can also cause poor engine performance in your Vibe. Keep an eye on your coolant levels and inspect for any signs of leaks or damage to the system.Ĭoolant loss through a head gasket failure should correlate with white smoke. ![]() ![]() If the engine coolant level is going down, but there’s no noticeable leak, it could be a sign that the head gasket has blown. One of the first symptoms you might notice when your Pontiac Vibe has a blown head gasket is a loss of coolant. Symptoms of Blown Head Gasket Coolant Loss To protect your head gasket, make sure that you always use the appropriate octane-level fuel for your car and address any engine issues, such as knocking or pinging as soon as they arise. When the engine experiences pre-ignition, it can create abnormally high cylinder pressure, which may cause the head gasket to fail. Engine DetonationĮngine detonation, or pre-ignition issues, is another factor that can contribute to a blown head gasket in a Pontiac Vibe. It’s essential to keep an eye on your engine oil and coolant levels and address any concerns with a trusted mechanic. Your head gasket is designed to withstand a significant amount of stress and heat, but as it ages and wears, it may no longer seal properly.Įnsuring that your head gasket is in good condition through regular maintenance and addressing symptoms of wear early can help prevent a blown head gasket. This could be due to a bad radiator, radiator hoses, or water pump. Poor Coolant Flow– If there is not enough coolant flowing through the engine, it’ll overheat.When it refuses to open, the engine can get hot enough that it’ll crack a head or blow a head gasket. Bad Thermostat– The thermostat’s job is to regulate the flow of coolant in and out of your Vibe’s engine.Low engine coolant can be both the cause and a symptom of a blown head gasket. Low Engine Coolant– If there is not enough coolant to properly cool the engine, it’ll overheat and blow the head gasket.It is crucial that you monitor your coolant levels and address any overheating issues promptly to prevent head gasket failure. When your engine overheats, the metal expands, potentially pinching the head gasket and reducing its ability to seal properly. ![]() Overheating is one of the most common causes of a blown head gasket in a Pontiac Vibe. Addressing these issues early on will help prevent the inconvenience and potential financial burden of a blown head gasket. Various factors contribute to a head gasket failure in a Pontiac Vibe, such as regular wear and tear, engine overheating, or incorrect installation. By being aware of these symptoms, you can quickly diagnose and address the problem, minimizing the impact on your vehicle’s performance and longevity. You might also notice white smoke coming from the exhaust or a milky discoloration in the oil. When the gasket fails, it can cause several issues, such as poor engine performance, overheating, and coolant leaks. Recognizing the signs of a blown head gasket in your Pontiac Vibe is crucial for taking appropriate action. Below you’ll find the symptoms, causes, and price of a Pontiac Vibe head gasket. If your Pontiac Vibe has blown a head gasket, you may find it running poorly or not at all. One of the most common (and) critical major engine problems is a blown head gasket. ![]()
