Air Filters and Intake Manifolds

Air filters are devices that remove solid particles such as dust, mold, and bacteria from the air. Used in building ventilation systems and engines, they contain an intake manifold that is primarily tasked to optimize the system/engine’s performance and efficiency.

What is Divertless Supersonic Intakes?

Divertless Supersonic Intakes (DSI) is an air intake that was designed for supersonic flight regime, so the plane doesn´t need to have any variable-geometry airintake, that´s why it is called DSI. In supersoniv flight regime, it is hard for an airplane to turn, especially kulbit. In order to gain airflow to the engine, most fighters uses variable-geometry air intakes, or moving air intakes that we could found in F-22, or Su-27, or MiG-29, or any other fighters. Fighter such like F-35 doesn´t need any moving parts because it uses DSI. DSI automatically gain airflow to the engine in supersonic flight regime. I hope it helps, have a nice day!

How do you replace the cabin air filter on a Taurus - Sable?

You have to remove the windshield wiper arms, then take off the plastic molding that lies between your windshield. Once that is off (it comes out in two pieces) on the passenger side of the car, under the windshield just behind the firewall there is a plastic rain shield with two screws. Remove the rain shield. The cabin filter is under that rain shield. FYI...every bolt is metric, and be careful when removing the plastic molding-only turn those screws a half turn, they break very easily!

I replace mine with out removing wipers. The upper plastic panel directly below the arms can be disconnected from the lower panel by removing some push on sheet-metal retainers. The wiper panel can be lifted enough to remove and replace the cabin filter. PS, nothing is required on driver side, only the passenger side.

The illustrated steps to replacing the cabin air filter are

included in the Owners Manual.

See "Related Questions" below

Open the hood and look at the passenger side near the firewall. Remove the black plastic piece near the windshield. It has a few clips that can be pried off with a flat screw driver. Remove the two Phillips screws and pull out the second plastic shield. The air filter is triangular in shape and fits into a space in the corner. Replace the filter and then put the two shields back on.

The filter is located under the hood, just in front of the windshield on the passenger side under the cowl grille. The steps you would follow are:

1- Open the hood. The filter section is on the passenger side.

2- I removed 3 push-on- clamps to open the grille. I found it was filled with trash. Clean out debris.

3- Unsnapped (the best I can describe it) a part that held the filter down and then remove and relpace the filter.

5- Then put everything back together.

It's located under the cowling on the passenger side. Remove the screws holding the plastic cowling in place and then replace the filter.

This filter is to be found on the passenger side outside the passenger compartment. With the hood closed, remove a few plastic screws holding the passenger-side half of the cowling (between the hood and the windshield). Now open the hood and remove a few metal clips holding this same passenger-side half of the cowling. This cowling will now come off.

Now you need to remove two small bolts holding another plastic part that is blocking access to the filter.

It took me 15 minutes to replace the cabin filter.

If it has one it should be in the right hand cowl.under hood up near windshield usually there is an identifing sticker , remove a screw & plastic piece of cowl & filter is inside. It can be blown out or replaced.

It is underneath the black plastic pieces under/below the wipers. There are just a few round fasteners that hold down the passenger side piece that need to be removed to access the filter.

Accessing & changing the cabin filter is well detailed and illustrated in the Owners Manual - See "Related Questions" below for more

Ive looked in the 1997 Taurus manual from cover to cover there is no guide to replacing this filter

How can you find out the true mileage on a vehicle?

This is from a pamphlet published by the Federal Consumer Information Center:

The National Highway Traffic Safety Administration (NHTSA) estimates that consumers lose billions of dollars a year to odometer fraud. Odometer readings may be rolled back or documents can be forged. Making miles disappear helps increase the car's value to the seller, but can mean increased maintenance and repair costs to the buyer. ... you can use the 17-digit vehicle identification number (VIN) to secure a history from either the state or a private vehicle history company. These companies have compiled data from multiple sources to help you get a better picture of the used car's past.

Is there inexpensive way to check for leaks in the intake manifold?

Yes, while the engine is running (in park) spray gumout/carb cleaner along the egdes of the intake. If the motor runs smoother or better then that tells you the intake is leaking. This, however, could cause a fire. A safer way is to use an unlighted propane torch. Turn the fuel on low and slowly move it along the hoses and gasket surfaces. When the engine speeds up, you have found your leak. if you are not sure if there is a leak in the intake ;a good way is when the engine is at idel carefuly place a rag over the carb or throttle body slowley closing the opening ( hold the rag tightly )while slowley placing the rag over the intaks ; if you notice an increase in RPM then you probley have a vacumm leak; to help pin point the leak use a spray with water and slowley go around the base of the carb ;manifold and vacuum lines when the RPM'S increase check that area for leaks ; cracked vacuum lines ;intake gaskets leaking this should help

How often should you change the filter on your heating and AC unit?

Summary

It all depends where you live -- what the air pollution levels are in your area, and what kinds of pollutants you have inside your house.

One should at least inspect the filter every 30 days and change it if necessary. If clean, check at least every 45 days. If a central air conditioning and heating system is used regularly, the filter should be changed at least once a year.

A filter change costs a couple of dollars, but it is the most important thing you can do to avoid problems later. if you let it go, the blower motor works harder, shortening its life or your evaporator coil could become your filter, blocking airflow and causing it to start icing up; this can cost hundreds of dollars to remedy.

If you smoke in your house, have inside pets, or a large amount of traffic in the house, check the filter once a week. The outside environment should be considered, since dust storms and high pollution areas do affect the filter as well.

How do you change the cabin air filter in a Honda Pilot?

For 2009 or later Honda Pilot, it is very easy - a 5 minute job - and no tools required. The filters are around $25 from Honda (80292-SHJ-A41) but much cheaper after market.

  1. Empty and open the glovebox.
  2. Press the 2 tabs on the sides.
  3. Swing the glovebox ALL the way towards the floor so the opening behind the glovebox is fully accessible.
  4. Inside the opening is a black tray - around 8" square. Press the 2 "tabs" on each side of tray and pull the tray out.
  5. Put the new filter in with the arrow on the side of the filter facing DOWN towards the floor.
  6. Slide the tray back in.
  7. Close the glovebox.

I changed mine at 19K and it was VERY dirty. I would recommend changing every year - especially if you have allergies.

For 2008 and older - you need to cut the plastic tab and take out screws.

Where is the PCV valve located on a 1995 Buick Riviera supercharged 3800 engine?

Hey MM==As far as I know it is like the rest of the 3800 engines and in in the intake manifold. There should be a hose going from it to the throtle body. Good luck Joe To replace the PCV valve: 1) Remove SC plastic shroud, 2) Note the black plastic PCV cover about 3 inches to the right of the shroud bolt, on top of the SC/Intake Manifold. It does not have a hose connected to it!! 3) Remove the 2 10mm bolts and lift off the PCV Cover. 4) A hold down coil spring can be removed and 5) the PCV valve sits in the recess. Reverse assembly with new PCV valve. With this location DO NOT EXPECT big change in operation - the old valve just gets a little varnished...

What is the purpose of an air intake with a filter in the hallway that is open to the attic?

I assume that this is the only return filter going to your furnance which would be located in the attic. Check all other bedrooms and see if there are 2 grill openings in the ceiling (meaning that room has its own supply register and return register) or if there is only 1 grill register in each bedroom.If only 1 grill register in every room than this is your only return grill intake for the furnance.this filter should be checked every 30-45 days and replaced if dirty.Keeping this filter clean will keep your furnance running at its peak performance. If however there are 2 grill openings in your bedrooms then you will have to go into the attic and check the filter inside your furnance also.I assume your home is single level with one heat system?

How do you replace the cabin air filter on a Ford Windstar?

The cabin air filter is located on the passenger side of the vehicle under the hood. It is in the plastic area that runs between the hinges. You will see a small flap to lift, the filter is behind that. If it is like the 2002 model. Open the hood. On the big plastic piece where the wipers go through, in front of the windshield, there is a small rectangular plastic piece. It is on the passenger side. It should be facing the front of vehicle. It is located behind that. There is a 4" wide by 1" tall black plastic cover that provides access to the cabin filter. It is on the front side of the cowl (black trim piece beneath the wipers), just to the right of the passenger side edge - accessed from inside the engine compartment. This cover just pries off.

The filter then can be lifted up and pulled towards you for removal. The cabin filter costs around $12

Easy, open the hood, below the passenger wiper on the front edge of the black plastic vent, you must see a slide plastic door that actually has an arrow sign pointing to the right, slide it out and inside you will see the air filter, install in the opposite way you remove the old one. the arrow should point up Try using some of the commercially available spray especially formulated for your kind of problems from any auto stores. Read the instructions on the label and follow. You can easily get rid of it. I tried it and it works! Good luck. Open the hood. If you look straight on at the engine it should be on the passenger side facing you. It is a small rectangular plastic piece that comes out. This is located on the big plastic piece where your wipers and such are mounted through. The cabin filter on my van is located on the plastic cover below the passenger side windshield wiper near the rubber seal, you'll have to open the engine hood to gain access. There is a rectangular plastic cover which you just pry off, then just lift and pull out your filter to replace it. Under the hood on the passenger side above the power steering pump

How do you replace the intake manifold gasket on a 1990 4x4 Chevy 1500?

Hey Allan===It depends on what engine you have but both are probably the same labor wise. You really need guidance and the best is to get a manual from a parts store and it should have pictures and everything. GoodluckJoe

If you buy an Edelbrock, they come with instructions... Best tip is to insure a good seal, using gasket sealer. The front and rear are known to leak from not enough sealer....and make sure to use a torque wrench, tightening in order and to specs. Recheck and retorque if necessary at next oil change.

Good luck!

Can there be an antifreeze leak from the intake manifold but not any antifreeze mixed in with the engine oil?

there can be a leak from the intake manifold without any antifreeze mixing with your oil, i personally experienced this problem on a 1986 sentra after a changed the head gasket, i apparently had scaped a little to hard on the intake when cleaning it for new gaskets. if its a small leak it would probably just be evaporating in the combustion chamber, but it can and probably will become a problem that needs attention quickly. have a trusted mechanic take a look at it as soon as possible, maybe have them do a compression check to see if there are any possible leaks. well good luck

How do you replace the Air Conditioning filter on a 2002 Toyota Camry?

The filter is in back of the glove compartment. Open the glove compartment and squeeze the back and it will partially drop down. There is a screw on the right hand side that you take off and pull the compartment down. The filter pulls out on the left hand side. It is not rocket science.

Sorry, the Gen I Solara doesn't have a cabin air filter. Those were introduced on the Gen II (2004 and later) and are accessed per the instruction above.

How do you repair intake manifold leaks?

Replace the manifold gaskets.

Word to the Wise: It would help to know what caused the leak. Bolts not tightened in correct pattern or torque, or just old age? Also, if manifold is aluminum, don't gouge the gasket mounting surfaces, only smooth w/ the yellow fingers tool you can get from SnapOn, or use fine sandpaper and a sanding block. Don't polish the surfaces either, or the gasket will slip or blow out.
