Loosen two bolts on exhaust manifold and replace donut If it's an 8-valve, then it's probable that the exhaust header has burnt through where it transitions from vertical to horizontal just before connecting to the catalytic converter A new header collector can be fabricated in-place at some shops... check around.

Could a bad donut gasket be responsive for a lack of power and bad fuel economy?

All a donut gasket does is provide a seal between your exhaust and your manifold. If anything you may get better mileage because there is less restriction on your exhaust. The bad part is you may get some fumes in the passenger area. ==Another Answer== A bad donut gasket could in fact cause these symptoms. It will allow excess oxygen into the exhaust stream, tricking the oxygen sensor into thinking the engine is running lean, making it add fuel and make the engine run rich. This will hurt fuel economy and power.

Where can you buy a donut for a Saturn sl1?

The gasket between the exhaust manifold and the exhaust headpipe is often called a "donut". It's a specially designed composite gasket, that can endure the pressure and heat of the exhaust system. Measure the diameter of the headpipe, then you should be able to go to just about any auto parts retailer and request a gasket of that diameter. OReilly auto parts, Auto Zone, Pep Boys and any local auto parts retailer should be able to help you.

How do you replace donut gaskets on 1997 suburban exhaust?

Remove the three bolts between the exhaust manafold and the downpipe. Separate the connection and remove the old gasket. You may have to pull down (a little) on the downpipe to remove the old one. The install is the reverse order of these directions. It should take you about 30 minutes. Its a Very easy procedure.

A exhaust manifold that is warped, cracked, or missing a gasket will make a sound like a engine miss. I usually look for soot near the suspected area to tell for sure.

How do you change the donut gasket on a Ford Probe GT?

I agree with the below comments. I am no mechanic, but have some ability. Changing the alternator was no small task. I actually was able to get the alternator out through the top, but at the expense of removing A/C connections and many words I would not want my children to hear. Fortunately, the A/C needed recharged anyway. If I ever have another alternator problem, I'm going to a gargage..... If you are not mechanically inclined, don't try it. If so, disconnect exhaust pipe from exhaust manifold going to catalytic converter, including bracket mount holding the exhaust pipe to convertor. Disconnect ground cable from battery, disconnect large wire on alternator (#10 metric wrench) and unplug quick connect wires. Loosen belt tensioner after loosing both mounting bolts. One is a pivot, one is a slide bracket. Now the fun begins, drop the alternator down through the bottom. Very tight, that's why you have to disconnect exhaust system. Reverse order for installation. Make sure you replace the "donut" gasket on the exhaust pipe or it will leak. Good luck

How do you replace a donut gasket in a Jeep Cherokee?

really you just have to look at it, if you mean that ring on the exhaust, just look at the seam that is leaking and look how it comes apart. typically its 2 or 3 bolts and its off then pop off the old ring, and replace it, then put it all back together. and good as new. PS put some antiseize on the threads before you put it back together, and spray them down with wd40 or something to help get them off easier.

How do you replace the exhaust donut?

You need heat and air tools! Use an Acetylene torch to heat the manifold cherry red where the studs are one at a time and use your impact tool to back out the stud. If you don't heat the metal surrounding the stud enough, the stud will snap off. Be prepared to replace the studs. also make sure the area you heat is greese free and have a water sprayer on hand to put out any unnecessary flames. A heat shield will help. Once the connection is free, pry out the donut. Replace the studs that back out, then insert the new donut.

How do you install a donut gasket on a 95 ford escort?

first off get some WD-40 and some deep well sockets that will fit the nuts on the exhaust. Make sure you soak the nuts well with the D40 because they lock to the threads because of the heat. Once you get the nuts loosened set the new gasket into the inset depression on the pipe and tighten just make sure you don't over thighten the nuts or they will snap off and then you have major problems.

Is it difficult and or expensive putting the exhaust system on a 1983 Chevy caprice classic?

If you are replacing it from the donut gasket to the tail pipe, You'd be better off to take it to a muffler shoppe. There are specific bends in the pipes where they bend around the tranny. You should be looking in the 200-250 range, about 2 hrs of work, for OEM parts... Is it a V8? If so, splurge... go to a specialty shoppe and have stainless steel dual exhaust put on it... the performance and sound are well worth the money.

What does an exhaust donut in a 1997 Dodge Neon do if you were told to replace this part because the vehicle would sputter at a higher RPM before shifting?

This little gem goes in the tailpipe where your exaust header bolts to the pipe leading to your catalytic converter. Apparently someone thinks you have an exaust leak, causing the sputter.

What could cause aftermarket exhaust system to sound so quiet from one day to the next?

HOUNDDAWG Sayz: You didn't mention if the muffler and catalytic converter are new or if you simply re- piped old ones. When a dying catalytic converter has burned off most of the inside platinum plating it will, depending on ambient and engine exhaust temps sound different from day to day. (they also tend to backfire) Superheated platinum completely consumes the unburned fuel in the exhaust gases (no, engine valve combustion doesn't completely burn the fuel before the exhaust valves open, and yes, increased efficiency/fuel consumption due to the catalytic converter increases engine horsepower, with the added benefit of reduced greenhouse gasses and cleaner air for us to breathe) If that's the problem then it's time for a new CC. Or, a muffler baffle could be floating loose, possibly from a broken weld inside. Or, a old muffler patch is loose or the muffler has rusted through. Time for a new muffler. Or, your flange gasket (in auto repair vernacular, the "donut") is broken or burned through or one of the flange bolts is broken and as "it" (the gasket and or the flange for the exhaust system pipe) shifts from road shock it allows unsuppressed engine noise to slip past the "donut" and escape. (the gasket is between the engine block and the exhaust system) Is it possible that a hanger or muffler clamp is loose, broken, rusted or missing and the exhaust piping can shift, opening gaps where the sections are clamped together? In any case a visual inspection (on a lift with a drop light and inspection mirror) will likely isolate the problem. If there is no apparent physical damage, missing hardware or loose sections of piping the problem will be in the catalytic converter and or muffler. If the (somewhat pricey) CC is bad it's best to replace the (relatively cheap) muffler at the same time.

How do I replace the Rav 4 headlight assemblies?

First make sure you have plenty of headlight fluid and blinker fluid. Then you need to use one of those left handed screw drivers to remove the bolts. Then make sure your 710 cap is screwed on tightly. If it is then check your donut exhaust to make sure u get proper flow.

Why is the car seriously loud during acceleration or just mid to high rpms it is 99 corolla ce roughly 122k m?

It depends on where the noise is coming from, mine blew the donut gasket where the header pipes come together to connect to the exhaust system. It isn't too hard to replace, might as well change the shoulder bolts that hold it together at the same time. I suggest you get the parts from the dealer, the aftermarket gasket I bought the first time was by "Felpro" and while they showed me the listing and they had it correct the gasket was not right. You should be able to identify if this is the problem by running the engine with the transmission in park, rev it at the throttle by hand and listen. If you do this when the engine is cold you have a few seconds where you can place your hand down along side the exhaust header and feel for air. I say seconds because I burned my wrist within 10 or 15 seconds so it heats up fast. To do this you have to remove the heat shield, or you can probably jack the car up, block it for safety (making sure the parking brake is set and the transmission is in park) and climb under behind the front wheel. Have a friend or your wife rev the engine (make it a family affair, I have my 8 year old son, 19 year old daughter or my wife help me bleed brakes etc.) Feel for air flow and listen for noise, even if it isn't the donut gasket (that is what it really is called) you should be able to isolate the problem if it is exhaust related. I had a similar problem. Mine turned out to be the tensioner on the timing chain. It had worn almost completely away. Use an automotive stethoscope to isolate where the noise is coming from and you should be able to figure out the cause fairly easily.
