you need a big wrench (1 1/16") a 14 mm wrench, and a 12mm socket with ratchet and 4" extension. loosen the large fitting on the bottom of the valve with the big wrench, remove the vacuum hose from the top of the valve, remove the 2 12mm nuts on the valve and the 12mm bolt on the plenum support bracket. slide the bracket out of the way then pull the valve away from the studs enough to slide it off the stainless exhaust supply pipe. slide the rubber hose off the sensor tube and unplug the egr temp sensor. remove the sensor with the 14mm wrench and install it on the new valve. the rest of the installation is reverse of removal.
