why egr cooler is required?

The EGR cooler is a component used to lower the temperature of the exhaust gases that are recirculated by the EGR system. The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions.

The TRD isn't super loud but it's definitely a deeper tone. It's noticeable and you want a better sounding exhaust without gaining hp then get it. It's expensive but still a decent upgrade. This is it exactly.

Any four-stroke internal combustion engine needs at least two valves per cylinder: one for intake of air (and often fuel), and another for exhaust of combustion gases. ... More valves also provide additional cooling to the cylinder head.

Well, antifreeze and engine coolant are similar, but not the same. ... Ethylene Glycol prevents coolant liquid freezing within your radiator by lowering its freezing temperature, alongside lubricating the water pump and inhibiting corrosion. Engine coolant is a mixture of antifreeze and water, with a common ratio of 50:50.

Your car's cooling system needs coolant to keep it from overheating. Although water can be added to the radiator for this purpose, it's preferable to add a mixture of coolant and water because plain water can boil before the proper coolant will boil, causing your engine to overheat [source: pontiac].

The exhaust gas temperature (EGT) pyrometer can be one of the most important gauges on a turbo-diesel-powered vehicle. It can warn the driver of situations that are potentially damaging to the engine, and it can also be used as a guide for optimizing fuel economy. Diesel engines are not indestructible.

In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. ... For example methanol is more tolerant to EGR than gasoline.

An AC system is a closed system, and if there are no problems, coolant is not consumed by the vehicle, nor does it escape. Unless your auto's AC is in need of repair, there is no need to shut off the system. When there is not enough refrigerant in the AC, serious compressor damage may occur.

Al C. The EVRY mod "fakes out" the fuel temp sensor signal to the ECU into thinking that the fuel is colder. If the fuel is truly colder, it is more viscous, and requires more pump stroke to deliver the same amount of fuel in a given time than if the engine had been fully warmed.

If the EGR cooling system (06) develops a leak, water can escape into the EGR system and pass through the engine, accounting for gradual coolant loss. If that happens, the whole EGR body - which is typically one big stainless steel component - needs to be changed out. ... 05 - EGR valve.

A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.

A PCV valve helps keep a constant pressure within the engine block by releasing oil fumes when they get to a certain pressure and sending them into the fuel system to be reburned with the gas. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.

If it senses the engine temperature is high, or is not reading engine temperature at all, it would deactivate the air conditioning system. ... If the coolant temperature sensor is faulty and not providing readings to the ecu, the programming will deactivate the a/c also to protect the engine. Another issue can be air flow.

A cooling system flush is an inexpensive way to keep your vehicle in good working condition. Budget anywhere between $100 to $250 for a full flush, depending on what type of coolant your vehicle requires and the capacity of your cooling system.

An EGR delete is ILLEGAL in ALL 50 STATES. All vehicles are required to meet federal emissions standards. The penalty for an emissions component alteration can be in the thousands of dollars.

You should not run without the cabin air filter. Not only does it prevent all those particles from being breathed in by you and your passengers, but it also prevents particles from getting into and damaging the fan and ducting mechanisms in your HVAC system.
