Repair 7

The 2000 Honda Accord has a chambered muffler. A chambered muffler forces the exhaust through a series of chambers and passageways to reduce the sound and vibrations caused by the exhaust system. When the sound of the exhaust system begins to drown out the standard noises of the car, such as the engine or the radio, it is time to replace the muffler. Another way to tell is if exhaust is exiting the system anywhere other than the tail pipe.

Instructions

1

Drive the car backward up on to the car ramps. This allows easy access to the muffler.

2

Disconnect the negative battery terminal.

3

Apply the penetration oil to all of the muffler clamp nuts and fittings. These are most likely very rusty from driving through wet conditions and the heat.

4

Remove the muffler clamp. If the nuts are too difficult to remove or if the muffler has been welded, use the hacksaw and cut the muffler at the clamp.

5

Remove the nuts in the muffler hanger. Use the impact wrench to remove these nuts. They have been tightened and stressed due to heat.

6

Pry the muffler loose from its rubber straps. Inspect the rubber straps for damage.

7

Install the new muffler. Insert it into the strap and attach it to the left over muffler with the muffler clamp. Reattach the muffler hanger. Reattach the negative battery cable.

Rust can ruin a car, and it often hits the lowest part of the vehicle first. One of the most susceptible pieces to get damaged is usually the exhaust system. Theyre generally made out of welded pieces of pipe; when the weld is exposed to salt or water, it can start to rust. Stopping and preventing rust on welds around your muffler and exhaust welds is an easy task.

Instructions

1

Raise the vehicle using the jack and support it on all four corners using the jack stands. Make sure the vehicle is properly supported before you crawl underneath it.

2

Crawl underneath the vehicle and locate the first welded area on your exhaust. Mask off an area about 3 inches wide, 1 1/2-inch on either side of the weld, with the masking tape and masking paper.

3

Spray the exhaust with the hi-temp paint. This will stick to the exhaust even through extreme temperatures, and also protect the welds from further rusting.

4

Peel off the masking tape and masking paper.

5

Repeat this process for each weld on the exhaust.

6

Raise the vehicle off of the jack stands with the jack and lower it to the ground.

The first performance modification that many people make to their Yamaha V Star 650 is to change out the exhaust system for a better sound and more horsepower. As an added bonus, this isnt a difficult modification to do and can be done by almost anyone at home in their garage with just a few tools. But before the new exhaust goes on, the old muffler has to come off.

Instructions

1

Park the motorcycle on a level surface with plenty of room to work. You want to make sure that your bike wont roll anywhere needlessly and damage anything.

2

Unbolt the frame cover that goes around the exhaust using a 3/8-inch ratchet and socket. Place it to the side so that it doesnt get damaged.

3

Unbolt the clamp that connects the inlet of the lower muffler on the exhaust to the muffler using an open-end wrench.

4

Unbolt the clamp that secures the mufflers to the muffler bracket using a 3/8-inch ratchet and socket and an open-end wrench. You can find the clamp between the two mufflers on the exhaust.

5

Slide the mufflers off of the exhaust, making sure to work them around the frame so you dont damage anything.

When internal combustion engines run, the air and fuel combustion that takes place inside the cylinders releases moisture from the air, which generally gets sent out the exhaust system as water vapor or steam. If the engine and exhaust system are cold, moisture can condense from the steam to form a liquid that may drip out of the tailpipe.

Small Amounts

A small amount of water dripping from the tailpipe of a cold engine is normal, and should cause no concern. Some cars exhausts might drip constantly if they are used only for short trips, as the engine and exhaust system may never get hot enough to prevent the exhaust moisture from condensing back to liquid. The biggest danger of chronic small amounts of water in the exhaust system is the possibility of rusting out the system prematurely. Many exhaust systems are made from stainless steel to prevent rusting.

Large Amounts

If there are large amounts of water dripping from the tailpipe, it can be symptomatic of a leaky head-gasket, which is a serious and costly repair. Usually, when head gaskets begin leaking, the exhaust plume becomes quite thick and light colored and may emit a sweet odor. This is produced by your engine coolant being boiled and exhausted from the combustion chambers. Seek mechanical help immediately.

Considerations

When the air is humid, more moisture may be present in automobile exhaust. Likewise, if the air is cold, some moisture may drip from the exhaust pipe until the engine and system get hot. If the amount of moisture dripping from exhaust pipes appears excessive, have a reputable mechanic look at the vehicle.

The muffler on your Buick Park Avenue reduces the loud noise produced by exhaust system pressure during engine operation. Along with this noise, the exhaust system carries fumes, water and acids produced during engine combustion. This poisonous combination of exhaust by-products eventually corrodes the exhaust pipes and muffler after a period of service. If your muffler has already developed a leak, toxic gases may find their way into the passenger compartment and put the lives of any one on board in danger. Replace the rusted muffler as soon as possible.

Instructions

Remove the Muffler

1

Raise the rear of your Park Avenue using a floor jack and safely support it on 2 jack stands.

2

Place the floor jack underneath the muffler for support.

3

Put on your goggles to keep rust and dirt off your eyes. Cut the exhaust pipe as close as you can to the muffler, right before the welded joint. Use a hacksaw or exhaust pipe cutter.

4

Unfasten the exhaust-hanger nut from its bracket using a wrench or ratchet, ratchet extension and six-point socket to prevent rounding off the nut. If the nut is rusted and seems stuck, spray the nut and stud thread with penetrating oil. Wait a few minutes before attempting to remove the nut.

5

Lift the muffler from underneath the vehicle.

6

Apply a coat of automotive grease to the tail-pipe hanger rod and slide the rubber hanger off the rod.

Install the New Muffler

7

Set the new muffler in place by fitting the muffler neck over the exhaust pipe. Support the muffler using the floor jack.

8

Install the new U-clamp over the exhaust pipe and muffler neck joint. Do not tighten the clamp yet.

9

Apply a coat of automotive grease to the tail-pipe hanger rod and the inner diameter of the rubber hanger. Then slide the rubber hanger over the hanger rod.

10

Screw the muffler-hanger nut to the exhaust hanger bracket and tighten the nut using the ratchet, ratchet extension and six-point socket.

11

Align the muffler to the vehicle and tighten the U-clamp using the ratchet, ratchet extension and six-point socket.

12

Lower the vehicle.
