How to adjust timing chain 2003 honda accord

SOURCE: Adjusting headlights on 2003 honda accord

Further to Emmisionwiz's answer that worked for me - the holes are in the black plastic covering the radiator support, to each side more or less in line with the headlights. They are marked with an "A" and rotation directions for UP and DOWN. The Phillips screwdriver goes into the hole about 45 degrees from vertical and engages the adjusting rack, where the teeth of the Phillips screwdriver are the pinion. If you shine a flashlight down the hole you can see the rack teeth and all becomes clear. But you will need a long Phillips screwdriver and a little bit of luck.

In the owner's manual it says the lights are adjusted correctly at the dealership and if they need adjustment because of a trailer then take the car to a Honda certified mechanic.

I have a 2004 Accord also and the method is the same for that one too.

Rule of thumb this is a timeing belt and it should be changed every 75,000 mile as a general practice. I hope this helps, dont forget to rate my answer, thanks

SOURCE: Timing chain or belt for a 2004 Honda Accord

It depends, 4cyl. is a chain, the 6cyl. is a belt and it is an interference engine. I have not done this one yet, but Hondas are never that easy.

SOURCE: has a 2004-2006 honda accord 2.2 diesel, timing belt or chain?

Belt is better replace either about every 100.000 or you'll destroy the engine when it goes out

Belt is Better because it's easier to replace, therefore much cheaper

Chain is inside and in the oil bath so harder= more expensive

By the way. dealer says replace every 60K . 100K is a MAXIMUM

SOURCE: Does the 2009 Honda Accord EX have a timing belt

the 2.4L has a timing chain which is self adjusting and lasts the life of the engine. The v6 needs a timing belt replacement about every 90-105k miles.
Thank you,
