Chevrolet Express Distributor
The Chevrolet Express Distributor takes high voltage from one ignition coil and directs it to the spark plugs in the correct sequence at the right time, making it easy for a V8 or V6 engine to start and run smoothly. Within a cast, a rotor which drives a camshaft spins below a plastic cap, and as it sweeps past each tower, it hands off 15,000 to 40,000 volts which whizz down wires to the plugs. The initial models were dependent on breaker points, a condenser, and centrifugal and vacuum advance weights that interrupted the coil current and shifted the timing when the engine speed or load changed. A constant service requirement is imposed by points wear, arcing, and spring fatigue. Thus, in the 1970s drivers saw the appearance of the electronic Distributor using a toothed reluctor and a magnetic pickup. This device signaled a module to switch current. This eliminated most moving contacts and with it much unreliability. This unit also rotates the oil pump by the same shaft, but the electronic type gave a hotter spark, steadier advance, and far less maintenance. The Distributor cap protects the internal components inside the cap from moisture and carbon tracking. It is important to check the Distributor cap and rotor to avoid misfiring. When Chevrolet revamped the Express, later engines followed the lead of coil packs in removing the need for the traditional Distributor, although it doesn't hurt to know how it works on earlier Chevrolet Express models.

Chevrolet Express Distributor Parts Questions & Experts Answers
- Q: How to remove and install the distributor on various engines on Chevrolet Express?A:It is a guideline on how to remove and install the distributor in various engines. The first step to removing the distributor requires you to disconnect the negative battery terminal and take off the air intake duct or resonator. To position number one cylinder at TDC on compression stroke, rotate the crankshaft. Disconnect the electrical connector and coil high-tension cable from the distributor cap. Remove the cap and set it aside with spark plug wires still attached. Ensure that your distributor rotor is pointing to high-tension terminal of No. 1 cylinder then make a mark on the body of its distributor. Mark where you have put your distributor base towards engine block. Then, pull it up straight after removing hold-down bolt and clamp of distributor, marking below stopping point of rotor with second mark being made. In case you have to install a distributor again, check number one piston at TDC position again. Turn rotor until it is pointing approximately 42-degress counterclockwise from first mark. Put in place no more than one mark for reference purposes Align marks on manifold intake and distributor base apart from ensuring that rotor lies correctly as per initial marker/ point of reference in your engine block while inserting it into a car's engine block . Tighten bolt by installing restraints for clamp in place; Install Distributor Hold-Down Clamp; Completion Steps Are In Reverse Order Of Removal Being Done.
