Exhaust is one of the hardest things to replace without breaking bolts So the 1 st and up most thing is lubrication get a good penetrating oil liquid wrench,WD40,LPS whatever your parts guy suggests buy the large can now spray ever bolt you can see even the exhaust pipe flange nuts run until hot spray again let cool down over night spray again now you are ready to try to get the bolts out. place a socket with a ratchet 3/8 the handle should be at least 8 inches just slowly pull in a counter clock wise motion until you have reached about 45 lbs torque if bolt has not moved then stop try to tighten bolt a little then repeat on the real stubborn one use a long round steel rod go thru fender well and hit the bolt head really hard this will shock the threads to allow easier removal after all are removed then throw all those bolts away and install new ones with the new manifold and gasket..

SOURCE: exhaust leak

they don't go into the water jacket, but be careful not to drill any deeper than the bottom of the bolt hole or you can go through to the water jacket, a piece of rubber vacuum hose over the drill works well to limit the drill depth.

SOURCE: o2 sensors in a 97 gmc 1500 with 5.7 liter

bank 1 is the drivers side bank, so b1s1 would be the drivers side closest to the engine. if the truck is equipped with several 02 sensors then bank 2 or b2s1 would be passenger side closest to the engine. those are called upstream o2 sensors and the others downstream b1s2 and b1s2 b= bank 1= drivers side s=sensor 2=downstream. hope this helps.

1994 ford f150 oxygen sensor location


An Oxygen Sensor (O 2 S) or heated Oxygen Sensor (HO 2 S) is used on all engines. The sensor is mounted in the right side exhaust manifold on some V8 engines, while other V8 engines use a sensor in both right and left manifolds.

Heated oxygen sensors are located in the exhaust pipes below the exhaust manifolds. The sensors react with the oxygen in the exhaust gasses and generates a voltage based on this reaction. A low voltage indicates too much oxygen or a lean condition. Where as a high voltage indicates not enough oxygen or a rich condition.

Disconnect the Oxygen Sensor (O 2 S). Measure resistance between PWR and GND (heater) terminals of the sensor. If the reading is about 6 ohms at 68°F (20°C). the sensor's heater element is okay.

Hope this helps (remember to rating this free answer).

How to change exhaust manifold gasket


inner fenderwell and anything attached to it must be removed. you didn't say which side-driver's side e.g.r. tube needs removed before manifold , you'll need a 1 1/16 crows foot wrench. remove exaust pipe then manifold bolts then manifold .clean both surfaces to insure good seal reassemble.this is a 4 to 8 hr. job best left to a pro.

Ticking/Tapping when car starts but goes away???


I had what sounds like the exact same problem. It was an exhaust leak from the left (driver's) side exhaust manifold. This engine has a history of the manifold bolts breaking and causing the exhaust leak. The engine is also used on some Dodge vehicles. It sounds like a tick and I almost mistook it for a bad lifter. I took it to the local Jeep dealer who confirmed the exhaust leak. I replaced the left manifold completely and replaced bolts/gaskets on both sides (left/right) and it fixed the problem. Be careful, as the dealer tried to gouge me on the price. You are looking in the ball park of $600 parts/labor. I got parts for $120 and it took the better part of a work day to do the job.

Need to locate o2 sensor location bank 1 sensor 2. I replaced the one on top nearest the radiator, but still getting o2 error code for a different one. Need to find its location on a Hyundai Accent 2000


You need to check two things.

First, there is a heat shield on top of the front of the motor where the o2 sensor you already replaced is. It's got (4) 12mm bolts. Remove it and check the exhaust manifold (big thing you put the o2 sensor into) for cracks. If there are any cracks, you'll get o2 sensor codes. Replace the manifold.

Second, if the manifold is fine start the car and listen to the exhaust pipe under the engine for leaks. Or if you already know the exhaust is loud... that's gonna do it too. A leaking exhaust pipe on an Accent will set secondary o2 sensor codes.

SHOULD you try to change it yourself, you will need a 7/8" wrench, and a new o2 sensor, or flex pipe, or manifold depending on what's broke. Do NOT touch the tip of the new or old o2 sensor to ANYTHING when you take it out or install it or it will be ruined permanently. Run the car until it's at it's normal operating temperature. Raise the vehicle, and take the o2 sensor out of the car (see below to understand which one) using the 7/8" wrench or if you got fancy and bought an 02 sensor tool... use it.

Replace whatever parts are bad (manifold or pipe) or just replace the sensor you need. Then restart the car and take it to a parts store and have them clear the code. The code (and check engine light) won't return right away, it usually takes a few days. If you did everything right you should be good. If not, it's not a terribly expensive job to have done and by now you should be able to explain to them what's wrong based on what you found when you looked at the car. Just tell them everything you checked and what you saw.

Education: I'm not sure where that half baked answer about o2 sensor 1 being near cylinder one came from but here's the real deal.

Sensor 1 is always BEFORE the catalytic converter
Sensor 2 is always AFTER the catalytic converter

Bank 1 and Bank 2 refer to which SIDE of the exhaust on 6 and 8 cylinder engines. Bank 1 is usually left side, Bank 2 is usually right side.

So... O2 sensor B1S1 refers to the O2 sensor BEFORE the converter on the LEFT side of the motor.
