Fix High Exhaust Temperature in Your Car.


Exhaust gas temperature (EGT) is the temperature of the exhaust gases as they leave the engine. The normal EGT for a car engine is around 1,200-1,500 degrees Fahrenheit. However, if the EGT becomes too high, it can damage the engine.

There are a number of things that can cause high EGT, including:

  • A clogged exhaust system
  • A faulty oxygen sensor
  • A dirty fuel injector
  • A leaking head gasket
  • A problem with the engine’s cooling system

If you notice that your car’s EGT is high, it is important to have it checked by a Car Mechanic in Essex as soon as possible. High EGT can lead to a number of problems, including:

  • Engine damage
  • Reduced fuel economy
  • Increased emissions
  • Engine overheating

How to Fix High Exhaust Temperature

The specific steps involved in fixing high EGT will vary depending on the cause of the problem. However, some general steps that may be taken include:

  • Cleaning or replacing the exhaust system: This is the most common way to fix high EGT. A clogged exhaust system can restrict the flow of exhaust gases, which can cause the EGT to rise.
  • Replacing the oxygen sensor: The oxygen sensor helps the car’s computer regulate the air-fuel mixture. A faulty oxygen sensor can cause the car to run rich, which can lead to high EGT.
  • Cleaning or replacing the fuel injector: A dirty fuel injector can cause the car to run lean, which can also lead to high EGT.
  • Repairing or replacing the head gasket: A leaking head gasket can allow combustion gases to enter the cooling system, which can raise the EGT.
  • Repairing or replacing the engine’s cooling system: A problem with the engine’s cooling system can prevent the engine from running at its normal temperature, which can lead to high EGT.

If you are not comfortable fixing the problem yourself, it is important to take your car to a mechanic. A Smart Mechanic in Essex will be able to diagnose the cause of the high EGT and make the necessary car repairs.

Here are some tips to help prevent high exhaust temperature:

  • Keep your car’s engine well-maintained. This includes regular oil changes, tune-ups, and fluid checks.
  • Avoid driving your car at high speeds for extended periods of time.
  • If you are towing a heavy load, make sure your car is properly equipped.
  • Have your car’s exhaust system inspected regularly for leaks.

By following these tips, you can help keep your car’s exhaust temperature in check and prevent damage to your engine. If you are not sure how to fix high exhaust temperature, it is always best to consult with a mechanic.
