Your Lexus dealer can give you the part number you need if you just have your vin, I probably could to if I were at work. I pay 350.00 a month to have this database.

How do i take to cover off to change 07 air filter


The air intake should have 4 snaps on it to pull apart the air filter housing. Just unsnap, pull apart and replace. Also check and replace the Cabin Air Filter as this filter is not common with car owners. On the passenger side just below the windshield there will be a black plastic housing that will need to be removed, pull out that filter and replace.

i just replaced the cabin air filter on my 08 grand prix, had no airflow before, now with new filter airflow is increased 80%.

Feedback is appreciated.

How do i replace the altenator


1. Remove the plastic air intake system which includes the air filter, 1 vacuum hose, the tube that runs to the carb, the tube that runs off to the left. There are three bolts that hold the bottom of the air filter housing on. Most of this system is a snap together assembly. Just pull it apart.

2. The alternator will have two bolts on the front bottom. The left one is a double sided bolt and the right one is a pass through bolt with a nut on the back. Stick a wrench or a short socket wrench on the nut behind the alternator and remove the pass through bolt from the front. Then remove the double sided bolt from the left side.

3. This leaves the alternator loose and being held by the belt. remove the belt from the alternator and wiggle and jiggle the alternator out of the mounting area (very tight squeeze to get it out). You can put a larger size can of fruit or something in the place of the alternator to hold the belt in place so you can remember how it looks.

4. You will need to loosen the belt tensioner to put the belt on the new alternator. Remove the can of fruit if you chose to do that but be careful to not accidentally remove the belt from the 5 or 6 different places it passes through. Place the new alternator, put in the bolts and tighten. Loosen the tensioner and put the belt on. Tighten the tensioner and adjust as needed. Replace the entire air intake system by snapping it all back together and bolting it in one piece at a time.

Does the bumber need to be removed to replace headlights


Here are the full instructions for both right and left.

Passenger Side:

1) Use a 10 mm socket to remove the two bolts on the radiator overflow bottle. Move the bottle and place it in an upright position between the radiator and the dipstick (if the engine is cold) or on top of the grille by the hood release. You will notice that the overflow rubber tube will lift off the windshield-washer bottle cap. Replace the cap so nothing falls in.

2) On the passenger-side fender you will see a bracket that one of the bolts came from. That too is bolted to the fender with a 10 mm head bolt. Remove the bolt and bracket.

3) You will see a large round cover; this is where the low beam bulb is located. Remove the cover by turning it right/clockwise (as viewed from the outside-front of the
car) or by turning it left/counterclockwise (as viewed from inside the car). When you can no longer turn the cover, pull it out.

Note: I found it difficult to align the covers behind the lights. You have to figure out which little square goes where on the lamp assembly. I put a mark on the cover before I took it off and then I put another mark on the lamp assembly, aligned with the mark on the cover, after I turned the cover to remove it. Doing this will make it easy to reinstall the cover.

4) The cover has a rubber gasket inside the will prevent you from completely removing the cover. However, you can pull the cover back a few inches and change the bulb. I suggest that you see how the bulb goes in so it aligns correctly.

5) There is a metal clip that holds in all H1 bulbs. This one is a real pain to get off. On the bottom of the bulb housing you will see a little ring. First push it down (towards the ground), then push it to the left (as viewed from the outside-front of the car). You may want to use a 4" long piece of tape to hold the clip up and out of the way.

6) Put the bulb in and clip it in place.

7) To install the turn-signal and high-beam lights, simply turn each to the right/clockwise (as viewed from the outside-front of the car) or left/counterclockwise (as viewed from inside the car) and pull the bulb out.

8) Put everything back together.

Driver Side:

1) Remove the 10 mm bolt that holds the air box down (this is on the gold colored bracket on the driver-side fender).

2) Release the two clips that hold the air-filter box together and remove the filter. You can then lift the top of the air box out of the way.

3) (see pictures) Pull the plastic tube from the under-hood "ram air" assembly towards the front of the car (it will move about 1/4 inch) and then pull the air box and straight out. It takes a little force because it is held in place by two rubber-male shaped plugs that go into holes. Once you have this out, the bulbs are easy to access.

Replacing the air box:

4) Align the air box’s two pointed rubber connectors with their holes and push down hard. Make sure the front air tube is out of the way. One note: there is another intake path at the bottom of the air box. Make sure that the air box is properly aligned with it and the “ram air” intake.

5) After you get the bottom of the air box in, install the bolt on the fender, replace the air filter, and then finish putting everything on.

Note: Total time to remove everything, change the bulbs, and re-install was 15 minutes. I do suggest that after you get the bulbs in and are sure that the round covers are in place correctly (as I mentioned, that was the biggest problem I had) to turn the lights on and make sure they work. I say this because, as you will see, putting the covers on sometimes causes the red wire to disengage from the bulb.

Note: Once you get all the junk out of the way (the air box on the driver’s side and the radiator overflow on the passenger side) you will see a 10 mm bolt right in the middle of the headlight assembly. This is for headlight adjustment.

How to change air filters on 2007 Mercedes C230 Sport


I have '05, both should be similar:
1.Cabin air filter is located above battery on right side against firewall.
Release three latches, remove filter housing, slide old filter out (housing is flexible), insert new
one, reinstall housing.
2.Engine air filter is on the left side of the block (follow intake hose). Cover is retained with six screws
(six point star shape,I belive called Torox, bit/scredriver size 25). Loosen screws (don' t pull all the
way out of the cover) lift cover , and remove old filter. Insert new one, reinstall cover. DO NOT
OVERTORQUE SCREWS! Screw holes in plastic filter housing strip very easily.
Note: Intake hose is very flimsy, one on my car came apart and had to be replaced.
