I have an 02 TB with 113,000 miles, and looking to put a few replacement parts in my truck as she has treated me well over the years. I have just ordered 6 new Iridium Plugs and an air filter and some other items from rockauto. My questions is where are the plugs located on this engine? They must be hidden behind something. i have changed a few plugs in my time, but this is a bit embarrassing. A picture would be great if anyone has one...thanks in advance for your help..Royals


i found my answer searching on youtube...close this thread

I typed "trailblazer sparkplug change" and guess what was the first thing google gives for an answer. http://www.youtube.com/watch?v=0X6hYVeI9XQ
