• Q: How to replace the distributor on 2005 Chevrolet Silverado 1500?

  A: To replace the Distributor, the air cleaner outlet resonator needs to be removed and the cold electrical connectors from the straight propulsion (CMP) sensor and the gas/oil pressure sensor need to be disconnected. Then, take off the Ignition Coil wire from the coil and from the Distributor Cap, then the Spark Plug Wires by twisting each boot 1/2 turn and pull the wire boot. Screw out the Distributor Cap and take it off. Mark the position of the rotor in relation to the housing of the Distributor as well as Intake Manifold and pull out the Distributor hold down bolt then distrubutor thus observing that the rotor will move clock wise 42 degrees. When installing, use a second mark on the base of the Distributor for alignment. If a new Distributor needs to be installed, there must be two marks on the housing and they must be placed in the same location as the old one; rotor must be aligned with the second mark and the Distributor is to be installed in such a way that the rotor turns clockwise about 42 degrees. The rotor division should end on the mark on the Distributor base ; if it doesn't, the Distributor should be removed and replaced. Torque the Distributor hold down bolt to 25 n.m (18 lb ft), install the cap to the Distributor with new screws torqued to 2.4 n.m (21 lb in) and re-attach the cmp sensor and fuel pump/oil pressure sensor. Reattach the Ignition Coil wire by placing the coil wire nipple in an angle of 35 to 60 degrees aft of perpendicular from the engine centerline. If the malfunction indicator lamp (MIL) is on and dtc p1345, dist. Will be installed improperly. For the second installation, rotate the number 1 cylinder to top dead center (TDC) of the compression stroke, matching the crankshaft balancer marks with the engine front cover tabs. Line up the white paint mark on the Distributor stem with the pre-drilled indent hole in the gear to align the rotor segment with a v6 engine . Position the oil pump drive shaft with that of the Distributor drive tab using a long screwdriver and insert the Distributor into the engine with the spark plug towers parallel to the engine centerline, and the rotor segment parallel to this on the Distributor base. Hold down bolt on the Distributor to the front to 25 n.m (18 lb ft); install the Distributor Cap with new screws going to 2.4 n.m (21 lb in) and connect the cmp sensor and fuel pump/oil pressure sensor and reconnect the Ignition Coil wire in return going with the right orientation. In case the mil is on following the installation, please repeat the second installation procedure; in case it is not, install the air cleaner outlet resonator.
