• Q: How to replace the distributor on 2005 Chevrolet Blazer?

  A: To replace the Distributor, turn off ignition and remove the air cleaner assembly. Detach the Spark Plug Wires from the Distributor Cap, twist the boot boot 1/2 turn and pull only the wire boot. There are screws on the base of the Distributor keep connector, remove it then unscrew the 2 screws that hold the Distributor Cap to the housing and get rid of them. Take out the Distributor Cap and mark the position of the rotor with a grease pencil to the Distributor housing, and to the Intake Manifold. Remove mounting clamp hold down bolt, and remove the Distributor, noting the rotor rotate approximately 42 degrees counter-clockwise. Mark the base of the Distributor for adequate rotor alignment when putting the piece together. In case a new Distributor assembly is used, mark the new housing at the same spots as the original one. Move the new Distributor Cap if need be, but align the rotor with the second mark and use the Distributor to insert it into the engine, where the hold-down base comes in line with the Intake Manifold mounting hole. As the Distributor is installed, the rotor moves clockwise about 42 degrees; then it does not coincide with the mark on the distributer base, remove the Distributor and install it again. Snug the Distributor clamp bolt to 25 n.m (18 lb ft) and put the Distributor Cap back on with 2 new screws cinched to 2.4 n.m (21 lb in), reconnected the electrical connector, and connecting the Spark Plug Wires and ignition coil wire, making sure to identify the wire boot orientation. If the malfunction indicator lamp (MIL) is on after installing, and the code p1345 is detected, the Distributor has been improperly installed. For the second procedure of installation, turn the crankshaft balancer clockwise in order to align the alignment marks with the engine front-cover tabs, where the number 1 Piston is at top dead center of the compression stroke. Bring the white paint mark on the bottom stem of the Distributor into line with the pre-drilled indent hole in the gear. To prevent the no-start problem, locate the Distributor driven gear, shaft, and rotor hole for proper reassembly. Direct the Distributor into the engine, in such a way as that the spark plug towers are vertical to the center line of the engine. After fully seated, the rotor segment should be same as the pointer on the Distributor base; if not, the gear mesh misalignment may cause a need for perform the procedure again. Always use a torque wrench when tightening bolts/lmc l-2300 to 27 n.m (20 lb ft), Distributor clamp bolt to 25 n.m (18 lb ft), tighten Distributor Cap with 2 new screws to 2.4 n.m (21 lb in), to reconnect the 2 electrical connector, then attach the 2 Spark Plug Wires and the ignition coil wire being sure to note the correct orientation (below) of the wire boot. If mil is on after the installation varnish it again varying.
