Reduced Fuel Efficiency: Because you no longer have a proper seal, the breaks in your intake manifold gasket will throw off the fuel to air ratio as we mentioned. Your engine will start underperforming as a result which you'll notice with your inability to accelerate the way it used to or maintain speeds that you are used to. This means that the air that mixes with the fuel to create your combustion reaction will begin venting and your ratio will be thrown off. Poor Engine Performance : Because the gaskets in your intake manifold are used to ensure a proper amount of pressure in your engine, if they wear out and develop cracks or breaks not only will your coolant begin to leak out but you're also going to suffer pressure losses. You never want to run an engine too hot for too long. There will be no external sign that you have a leak, but obviously you're driving will start running hot and that can lead to more extensive damage and eventually much higher repair bills as a result.

This is especially true if the gaskets are leaking in a way that causes the coolant to leak inside the intake manifold rather than outside. Even with a minor leak that doesn't show any outward signs, this can eventually get to the point where the engine overheats. If the coolant leak gets bad enough or goes on for long enough then your engine will begin to overheat. The result of that is that your engine will not be able to maintain the proper temperature required for optimal functioning. Keep that in mind if you do see a leak, it should be cleaned up as soon as possible.Įngine Overheating : It stands to reason that if you have a coolant leak, then your entire coolant system is going to start to fail. However, antifreeze is also highly toxic and extremely dangerous. Some people haven't even tried to drink coolant as well, and there have been instances in the past where people have used it to cut wine in order to commit fraud because of the sweet taste. In fact, the smell of coolant is so enticing that many animals will come to try to drink it. Sweet Smell: Coolant has an unusually sweet odour to it that you'll notice if you have a coolant leak in your intake manifold.

However, if you experience several other symptoms at the same time then it's definitely a place you should consider looking. Coolant can leak from a number of different places in your car however, so you shouldn't assume right away that it was your intake manifold that caused the problem if you find coolant leaks. Coolant is typically either green or orange so this will help you distinguish it from other liquids that may leak from your vehicle. When it comes to coolant leaks from your intake manifold these are the signs that you definitely want to keep your eyes open for.Ĭoolant Puddles: Because coolant can start leaking out around faulty gaskets you may notice drops or puddles of coolant under the engine of your vehicle. When your intake manifold goes bad there are a few things that can indicate something is wrong. Signs and Symptoms of an Intake Manifold Coolant Leak If you start experiencing any of these problems take your vehicle to a mechanic as soon as you can to get it checked out.

If your intake manifold cracks or otherwise breaks down and starts leaking coolant there are some signs and symptoms that you can be on the lookout for to let you know that it's the intake manifold rather than another part of your engine that may be giving you troubles.
