Infiniti Q45 Intake Manifold Gasket
Diagnosing Your Infiniti Q45 Intake Manifold Gasket Problems Properly
You know that an internal combustion engine needs the right ratio of air to fuel to be able to perform at its peak, but have you ever wondered what helps it achieve this perfect combination? The answer lies in a simple, durable, and often neglected part of your engine. Set in between the air intake manifold, the cylinder heads, and the engine's block is the intake manifold gasket. It is a malleable material that seals the gap between these engine components and prevents air or the air-fuel mixture from escaping. When this gasket fails, you won't notice it until you observe your fuel economy decreasing. Higher emissions and poor engine performance are also symptoms of a damaged gasket. Here are some steps to take to diagnose an Infiniti Q45 intake manifold gasket problem correctly and some simple steps on how to take care of them.
External coolant leak
The thing to remember about a car's cooling system is that the amount of coolant coming from your radiator and coolant tank should be just enough to cool your car. Physically observing a coolant leak can be tricky, as it can vaporize from the heat of the engine. In this case you won't be able to find traces of the leak anywhere. Try this instead: observe how often you need to pour additional coolant on a regular basis. If you notice that you are adding coolant too often, then you might want to check the condition of your intake manifold gasket. A bad gasket can mean trouble for your engine.
Internal coolant leak and engine failure
Compared to an external coolant leak, an internal leak can contaminate the motor oil, degrade it, and damage the engine. The resulting damage is more evident than an external leak's-in this case, it can cause your engine to stop working. In advanced cases, it will cause the engine to eventually die in the middle of a long drive. Your intake manifold gasket is insidious that way: when it's damaged, you won't know there is a problem with it until something a major failure happens to your vehicle.
