Usually oxygen sensors are what would be screwed into the exhaust manifold.Usually oxygen sensors are what would be screwed into the exhaust manifold.
The year, engine size and if it is the intake manifold or an exhaust manifold gaskets would help.
asuming the vehicle has a 4 cylinder, the exhaust manifold would be facing the radiator. 6 cyl. would also have one facing the firewall. You can figure it out simply by tracing your exhaust system from back to front. tail pipe - muffler - exhaust pipe - catalytic converter - exhaust pipe - exhaust manifold - engine.
Probably on the exhaust manifold before catalytic converter
The turbocharger turbine housing and exhaust manifold on any state of the art high horsepower (per litre of displacement) diesel engine will glow red as it approaches full load condition.
The engine will have one exhaust manifold attached to each "bank" of cylinders. In a v6 or v8, there would be an exhaust manifold on each side of the 'V'. With the transverse mounting of the front wheel drive, the manifolds are at the front and back of the engine. On a 4 cylinder, there's only 1 bank, so just one exhaust manifold. (NOTE: there hasn't been a 4 cylinder Taurus since 1986) On the front and back of the engine it will have three pipes coming out of the engine that turn into one pipe that goes all the way back to the muffler
It is located about in center of the engine compartment on the backside of the motor against the firewall...right above the exhaust manifold. That would be the upstream o2 sensor. The downstream o2 sensor is located somewhere on the exhaust just after the exhaust manifold...
On a Ford Explorer bank 1 is the passenger side of the engine and sensor 1 is in the exhaust ( either the exhaust manifold or the exhaust pipe ) before the catalytic converter ( upstream )
Well I have the reverse, 454 manifolds on a 350, so I would think so.
what is the cost of repair of Toyota 4runner exhaust manifold
Air pressure difference between the heat at the manifold and the relative cold outside. The manifold can get very hot, which increases pressure towards to outer, cooler, opening. Also, the pressure of more exhaust gas being pump into the manifold from continued combustion from the engine.
if you would stand in front of the engine (in front of the timing belt),it should be on the left side of the engine block under the exhaust manifold
true dual exhaust would mean that each pipe would be atached to an exhaust manifold of its own. It might be a v6 or v8 or as in the old days an inline 6 whith a split manifold was popular.
Need to know if it is the intake manifold or an exhaust manifold and what is wrong with it.
Bank 1 sensor 1 would be threaded into the exhaust pipe directly after the exhaust manifold on the drivers side of the engine.
Some (front wheel drive) cars have a flexible piece of pipe that connects the exhaust manifold to rest of the exhaust system. The length of pipe is designed to allow the engine to rock back and forth on its mounts. Without the flex joint, the movement of the engine would damage the rest of the exhaust system.
Assuming this is a 4.3L engine, bank 2 sensor 1 would be located in the exhaust pipe immediately following the passenger side exhaust manifold.
Assuming you have the 4.3 engine, bank 2 sensor 1 would be the O2 sensor threaded into the exhaust pipe directly after the passenger side exhaust manifold.
You can find to right of the exhaust manifold sticking out to the engine.
Bank 1 and 2 reference a V type engine where there would be two exhaust manifolds. The Vortec 4200 Inline 6 cylinder engine hence has one exhaust manifold and the Oxygen sensor is mounted there. (passenger side of engine).
It would be a waste of time and money. You would have to make a special adapter to hook the exhaust to the manifold. On a turbo header, the exhaust hooks to the turbo and the turbo to the manifold.
Drivers side of engine would be bank 2. Bank 2 sensor 1 O2 sensor would be threaded into the exhaust pipe just after bank 2 exhaust manifold.
i header is much better than a manifold better it will give you increased air flow horse power and gas mileage
that would be either your catalytic converter or your resignator pipe.
