SOURCE: red hot exhaust manifods

Make sure that your catalytic converter and exhaust is not plugged..Also check for propper map sensor operation,the reading that the map sensor supplies to the pcm is used to adjust ignition timing and fuel delivery.If the timing is being retarded to far , the exhaust exiting the cylinders will be extremly hot and will produce the effect you are having...Good Luck...

SOURCE: Where exactly is the front O2 sensor on a 1999 S70?

For 1998 Volvo V70 2.4L MFI DOHC 5cyl the Oxygen Sensor is located under vehicle, center, below front seating area, mounted in top of exhaust pipe.

The oxygen sensor produces a voltage within 0 and 1 volt. When there is a large amount of oxygen present (lean mixture), the sensor produces a low voltage (less than 0.4v). When there is a lesser amount present (rich mixture) it produces a higher voltage (0.6-1.0v).The stoichiometric or correct fuel to air ratio will read between 0.4 and 0.6v. By monitoring the oxygen content and converting it to electrical voltage, the sensor acts as a rich-lean switch. The voltage is transmitted to the engine controller. The controller signals the power module to trigger the fuel injector.


Hope this helped (remmeber comment and rated this).

SOURCE: 1994 Buick LeSabre does not want to take gas and exhaust manifold gets red hot

If you've checked your coolant and the gas is good it is likely the timing is off drastically and it needs fixed. I don't remember if that car has a chain or belt. I know most manufacturers change intervals on timing belts run from 60-90 thousand miles.Good luck those are nice cars when they are running well.

Installed new TD04 turbo and vehicle ran perfect for a week or so. Last night drove 10 mins it is revving to fast and when i looked at exhaust manifold it was glowing red.

I would check your MAP or MAF sensor to be sure. Sounds like you are running lean which is causing your exhaust gas temperature (EGT) to be very high. Running lean with a turbocharged car will destroy your engine very quickly. Drive the car gently until you figure this out.
P0109 OBD II Trouble Code

Also, it is common for the exhaust manifold and downpipe to glow orange if the car has been driven in a spirited manner. Although, normal (not lead foot) driving shouldn't cause your EGTs to be this high.

Catalytic converter

The exhaust downpipe is glowing red with heat?
To be honest, that may be fuel-air /and or cylinder head problem. A downpipe gets very hot, yes, but they don't glow red.

A faulty oxygen sensor can cause the catalytic converter to overheat - with disastrous results.

If you're not sure what you're doing don't mess around with things. get somebody who knows what they are doing to look at your car and give you an opinion

I'm getting P0400 and P0235 on Renault Logan

P0400 Exhaust Gas Recirculation Flow Malfunction
P0235 Turbocharger Supercharger Boost Sensor Circuit Malfunction

I would say the EGR Valve is faulty- stuck open. I think the second code ( P0235) is being generated due to the EGR problem.

I need to find a free complete diagram for a turbo charger off of a 1987 toyota pickup 22ret

  1. Disconnect the negative battery cable.
  2. Drain the coolant.


When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. Disconnect the O2 sensor wire clamp and connector.
  2. Disconnect the Nos. 1 and 3 PCV hoses.

  1. Disconnect the Nos. 1 and 2 turbocharger water hoses.
  2. Loosen the clamp on the throttle body, remove the two nuts and lift off the air tube assembly.
  3. Remove the No. 1 air cleaner hose assembly and the No. 2 air cleaner hose.
  4. Remove the exhaust manifold and turbocharger heat insulators.
  5. Disconnect the No. 3 turbocharger water hose.
  6. Raise the truck and disconnect the exhaust pipe from the turbine outlet.
  7. Remove the turbocharger bracket stay.
  8. Disconnect the turbocharger oil pipe.
  9. Remove the turbocharger and exhaust manifold as an assembly.
  10. Remove the No. 2 turbocharger water pipe.
  11. Remove the oil pipe.
  12. Remove the No. 1 water pipe.
  13. Remove the turbine outlet elbow with the O2 sensor attached.
  14. Disconnect the turbocharger from the manifold.

To install:

  1. Pour approximately 20cc of new oil into the oil inlet and then turn the turbocharger impeller wheel so as to wet the bearing.
  2. Using a new gasket, attach the turbocharger to the manifold and tighten the nuts to 29 ft. lbs. (39 Nm).
  3. Install the turbine outlet elbow and tighten the nuts to 19 ft. lbs. (25 Nm).
  4. Install the No. 1 water pipe. Install the turbo oil pipe and tighten the nuts to 14 ft. lbs. (19 Nm).
  5. Install the No. 2 water pipe and then mount the assembly to the cylinder head.
  6. Install the oil pipe and tighten the union bolt to 20 ft. lbs. (27 Nm). Tighten the nuts to 14 ft. lbs. (19 Nm).
  7. Install the turbocharger bracket stay.
  8. Connect the exhaust pipe to the turbine outlet elbow and tighten the nuts to 32 ft. lbs. (43 Nm). Lower the truck.
  9. Connect the No. 3 water hose and install the heat insulators.
  10. Install the No. 2 air cleaner hose with the arrow facing the turbocharger and fasten the clip as shown.
  11. Install the air tube assembly. Connect the O2 sensor and clamp.
  12. Refill the engine with coolant, start it and check for leaks.

Nissan Navara STR 2006 d22 3lt turbo. Turbo is whistling very

Remember, what is heard as turbocharger noise may not be caused by a noisy turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration and increases or decreases with rpm and load. This condition is most often the result of a loose clamp/hose at the turbocharger compressor outlet, charge air cooler inlet, outlet or at the intake manifold.

1. With the engine running at idle and the transmission in Park or Neutral with the parking brake set, feel for boost air escaping at each connection between the turbocharger compressor outlet and intake manifold. For limited access areas, spray soapy water on those connectors and look for bubbles.

2. Check the exhaust manifold and exhaust system for leaks.

I hope this helped.

Thank you,

Does my 2002 S80 Volvo have turbo or not?

is this a t6? if so yes. turbocharged engines have more horsepower than naturally asprirated engines, a turbo charger works like a supercharger by forcing more air into the intake, while a super charger is usually belt driven a turbocharger is exhaust driven, it will be located in the exhaust pipe or exhaust manifold and is turned by exhaust gases passing thu with the opposite side connected to the air intake pipeing, some have the intake air piped thru a intercooler which is mounted in front of the radiator(cooler air is more horsepower)
type 2002 s80 volvo in your search bar and you can find a ton of info
