How do you replace the headlight bulb located on a 2002 Chevy Astro?

You need to remove the windshield wiper fluid and radiator over flow tank if it is on the passenger side to do that you need to disconnect the over flow tube from the radiator and then there are 2 connectors holding the tanks in they are black with a circle thing on top using a screwdriver lift the black circles up they come up about an inch then the rest just easily pulls up lift the tanks straight up (it will be a little tight) there is still a plug connected so you can either unplug it or just set the tanks on the engine and at this point you should be able to reach in and change the bulbs..good luck .. i just done mine and wasn't hard at all.

The headlight assembly is on a mounting bracket which is fastened to the frame. By removing the assy you can get access to both headlamps without disrupting the aiming mechanism. Use a 10mm nut driver or ratchet to remove 4 screws per assy. Two from front, one from the top corner that holds the fake side marker lens, and one from behind the side marker you just removed. This gives you access to both head lamps. This was for a 2003 Astro.
