Question about 2005 Chevrolet TrailBlazer
Have a friend, (or in-law) someone you're not too fond of, stand in front of the truck while you honk the horn and have them pinpoint it for you.

To change the sparks on a 2005 4.7L Dodge Dakota you will need the following:
Note you will have to remove the air intake located at the top of the engine, and will have to move some of the coolant lines out of the way.
At the top of the engine there are 4 sparks on each side. The coils are held in place with a 10mm bolt. Undo the 10mm bolt and unclip the coil. Next pull out the coil.
Insert the socket, with extension into the spark plug hole.
Remove spark plug.
Check the gap on new spark plug, it should match stock.
tighten to approximately 25ft.lbs. (check spark-plug packaging for exact torque requirements).
repeat this process with all other sparks.
be sure that no dirt gets into the spark plug holes.

You didn't mention what size engine you had. I am going to go with the most common engine and that would be the 4.2 liter engine. If this is your engine then the location of the thermostat is in the housing that the lower radiator hose connects to the engine. Just follow the lower hose and you will find the housing. Now you can't just buy a thermostat for it. The thing comes as a whole assembly housing and all and you can find it at your local auto parts store for about 25 dollars. Below is a picture of its location for you. The bottom bolt is not a problem to get off. The top one is another story and you have to get at it with a wrench and turn it a little at a time because you don't have much room to turn it. A little pointer is to do the top one first. trust me on this. Also when putting the O-ring which is the gasket for it you will need to use a VERY little bit of RTV to help hold it in place on the new housing when installing because it will fall out. remember to only use a little bit, just enough to hold it in place. If you use to much RTV it will leak. I hope this helps and is the engine you have and good luck.
