I haven't changed one yet so I can't say but I can tell you that you have to bleed the air out of the system afterward. There is a plug in the top metal hose (don't know it's correct name) on the passenger side. There is a square hole in it for a 1/4 drive. Run the engine with the plug out until the thermostat opens then you can put it back in.
