Automotive Exhaust System Replacement PARTS Exhaust Gasket Exhaust Pipe TOOLS Flashlight Floor Jack This guide requires the following supplies: Penetrating Oil Safety Tip: Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes. 1 Secure the vehicle on a level surface making sure the vehicle will not roll or lean when jacked up. 2 Using a jack, lift up the vehicle. Every vehicle comes from the factory with a jack. To locate and properly use this jack see the owner's manual. The owner's manual will inform you what proper jacking locations should be used. Photo may not be specific to your vehicle 3 Secure the vehicle with jack stands on both sides for safety before starting any work. The pinch welds or the frame rails are the two best locations to use. Do not rely on the jack to hold the vehicle up while working. 4 Inspect ...

Exhaust Pipe Smoke - White Car Engine Emits white Smoke Helpful Information The amount of steam produced from the tail pipe while the engine is cold varies due to outside temperature and humidity. Coolant/antifreeze is used to cool the engine during normal operation. If coolant is allowed to enter the combustion chamber, the engine will burn the coolant creating white smoke and steam. When this white smoke/steam is being produced it will be accompanied by a sweet, pungent odor and sometimes engine overheating. This condition will also be accompanied by engine coolant loss with no visible leaks. Combustion chamber coolant leaks can be tricky because the repairs can overlap, and its difficult to know which one it is before dis assembly. Example: A repair shop has determined coolant is entering the engine combustion chambers, as they disassemble the engine they discover the intake manifold gasket failed. It's up to the honesty of the repair shop to alert the customer the rep...

Blue Smoke from Exhaust Pipe Car Emits Blue Smoke From Exhaust Pipe Helpful Information Blue smoke is caused from several specific conditions inside the engine. This guide will help you determine what the problem is so it can be corrected. Blue smoke appears mostly at morning start up's because oil from the vehicle's engine is mixing with the gas inside the engine's combustion chambers, then burns together with the fuel from the injectors while the engine is running. This can result in an expensive repair, but not always. The more expensive, and usually terminal reason for blue smoke is the piston rings of the engine have worn out which is allowing engine oil to pass into the combustion chamber while the engine in running. In this case the engine is worn out and needs to be replaced. Best Practices Its important to note that if you decide to repair the engine, often you are looking at hourly repair rates plus parts and machine work. This is quite costly dependi...

Black Smoke From Exhaust Pipe Car Emits Black Smoke From Exhaust Pipe While Running Helpful Information Black smoke is caused when the mix of fuel and air inside the engine becomes un-balanced. Normal mixture is 14.5 parts air to1 part fuel. When the fuel to air mixtures change because of a malfunction the mixture can go as high as 14.5 to 2 or 3, two to three times the proper amount. The black smoke seen from the tail pipe is the excess fuel generated from the rich mixture. Malfunctions in fuel delivery or a leaking fuel pressure regulator will cause black smoke to be produced. The fuel injection system atomizes fuel by pushing it through a small nozzle of the fuel injector while under pressure. The computer system measures vacuum and air flow into the engine intake manifold to determine a proper amount of fuel that should be released. Airflow is controlled by the throttle body or throttle valve actuator (throttle) as fuel is distributed directly in each cylinder. The process ...

Exhaust System Working Of Vehicles Exhaust System Helpful Information Engines produce water and steam with the exhaust gases as a natural byproduct of the combustion process, which can be observed from the tailpipe in the first minutes of operation. As the engine heats up the water is vaporized quickly so the moisture is not visible. Most exhaust systems are made of aluminized metal or stainless steel to prevent corrosion.  A secondary muffler  i s sometimes used and referred to as a resonator, which increases the muffle affect. Fumes from exhaust gases are quite harmful and can cause complications including lightheadedness, blurred vision and death. After the engine has cooled down, inspect the system for cracks, holes or rust. When a new exhaust system is used for the first few times, its normal for unusual odors to be produced for a short time after. Performance Exhaust There are endless configurations of exhaust systems from the very loud (free flow, low rest...

Backfire How To Troubleshoot Car Backfire Problems Why Car Backfires There are typically two kinds of engine backfires , one is generated from the  intake manifold  of the engine , and the second is expelled from the  exhaust pipe  at the rear of the car. A backfire is an explosion of sorts in the intake manifold or the exhaust system. A backfire occurs when there is an imbalance in the air to fuel ratio required for your vehicle to operate properly. If the fuel mixture is too lean (not enough fuel) you may have a backfire in the intake, or too rich (too much fuel) you may get a backfire out of the exhaust system. Most backfires are easily repaired by correcting the imbalance and providing a greater or lesser percentage of fuel to the mixture. Common Problems and Solutions Most causes of backfires in the exhaust system can be addressed by troubleshooting the reason for the air to fuel ratio imbalance. The solution usually involves checking for...
