How do you remove the alternator on a Chevy trail blazer. I can remove the top bolts but how do you remove the bottom bolt because you can not see it from the top and a hose is in the way which hinders...

Using a ratcheting box end wrench works for me and many other TB and Envoy owners. Difficult little bugger with those lines in the way. Use the same method for the bottom bolt of the thermostat, same problem, IF that's what you're trying to get to.

How change the thermostat to a chevrolet trail blazer

Remove the alternator and the bracket. Easier to take off if the drivers front tire is off. Have fun with the 3rd bottom bolt on the alternator, it's a blast trying to get it off.

While you're removing the thermostat, you might as well replace the coolant temperature sensor like 2" above the T-stat. It's around $35 and very easy to do. The sensor screws into the block and has a wire coming off of it that will need to be unpluged to remove.

Where is the fuel filter located on my 2004 Chevy Trail Blazer? WE

On 05+ Trail Blazer, the fuel filter is integral with the fuel pump inside of the fuel tank. It is a non-serviceable part. On 02-04s, the filter is on the drivers side frame rail at about the B-pillar. If your trail Blazer is a late 04 which means that it was build close to the 05 Trail Blazer, you may have a non serviceable fuel filter. Good luck and check under your Trail Blazer or look at your manufactured date sticker on the door which would help you indicate if your 04 is a early Trail Blazer and you'll have the fuel filter on the inside frame rail under the driver's door.

Where are the sparkplugs located on a 4.2 inline 6 cylinder engine for chevy trail blazer

Under the top of the engine there is a cover. Remove this plastic cover and under you will find an individual coil on each cylinder held in place by a bolt. Unplug the coil, remove the bolt that holds the coil in place and twist apull up gently to remove the coil boot. Under the coil is the plug. Use platinum plugs that are rated for about 80k miles so you don't have to do this procedure but once every few years. Hope this helps, good luck
