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.
Your engine is only as good as its intake manifold gasket, which goes in between a few of your engine's main components. It helps keep the air-fuel mixture and coolant in their respective places and prevent them from leaking. But since your intake manifold gasket is subject to high temperatures, it has the tendency to develop cracks and holes that may compromise your engine's performance. In fact, even the smallest cracks or holes in the gasket can cause severe damage to your engine in time. Fortunately, you can keep your Infinit Q45 intake manifold gasket in tiptop shape by caring for it properly. Here are a few maintenance tips you can keep in mind to help this gasket last longer than its intended lifespan:
Take care when cleaning the gasket.
The intake manifold gasket is made of a malleable material. With enough force, it can be bent out of shape or can develop cracks when you are cleaning them. Take extra care when clearing it of any dirt or grime. Lay it down on a table and wipe it with a piece of clean cloth. Before you put it back on the engine block, make sure it is clear of any contaminant.
Clean the parts around the intake manifold gasket.
Whenever you do maintenance work on your car, don't forget to take time to clean your air intake manifold and the cylinder heads. Also, while you're at it, make sure your engine block is free of any substances that might cause it to heat up more than the standard operating temperature. Remember, the less contaminants your gasket and the components around it have, the longer the life of your gasket will be.
Lay the gaskets properly into place when replacing them.
When it's time to replace your intake manifold gasket, don't forget to lay it into place and make sure it fits properly. Take extra care not to let it cover any coolant passages. It is also a good idea to apply a thick bead of room temperature vulcanizing (RTV) silicone gasket sealant onto the rear and front lip of the engine block where the manifold sits. Lay a thinner layer of RTV sealant around the water passages on the engine block as well.
