You will either have to remove the transmission are pull the engine out.
It is what ever you think will be the easest for you. Then just knock the plug out, clean the hole with sand paper and drive the new one back in with a hammer and a socket that will fit in the freeze plug. Then put it all back together. There are 2 plugs in the back of the engine, replace both of them. You will see 1 plug in the center of the back of the block that is not a freeze plug, it is a cam plug do not bother that unless it is leaking engine OIL. Leave it alone.
The 2006 Chevy Trailblazer passenger side rear freeze plug is located near the back of the engine block. The freeze plug will be near the bottom of the engine block.
Yes there is.
replace it
It depends on what engine you have as to how many you have but they are in the sides and rear of the block.
Usually the block heater is in place of the passenger's side rear freeze plug
11, but one is actually the rear cam plug.
Drain coolant from radiator and engine block Remove passenger's side rear freeze plug and replace with block heater kit
Should be 1 at the front of engine 1 at the rear of engine on each side Punch a hole in the center of freeze plug and pry out
Should be three on each side and two in the rear under the bellhousing.
The hardest part of the job is GETTING TO the freeze plug. Depending on which one is leaking, sometimes you need to pull quite a bit of stuff just to get to the freeze plug. You need to be able to examine it and have clear access to the freeze plug and if it's one of the rear plugs (under the flywheel), you're only option is to pull the engine and/or transmission. Once you can get to it, just drive a screwdriver or other sharp object through the freeze plug and pry it out. Clean the block around the freeze plug then install one of the aftermarket types, preferably one that allows you to tighten a bolt to install it. You'll have trouble getting an original type freeze plug to seal if you don't have the engine block sitting on a workbench. Any time you have an engine machined, always replace the freeze plugs.
You will either have to remove the transmission and fly-wheel to remove them or you can pull the engine out and then remove them.
2 in front, 3 on each side, and 3 in back, however, 1 is actually a plug for the rear of the camshaft.
