How to Replace the Distributor in a Geo Metro

The Geo Metro gained popularity because its small engine had big gas mileage. If you own a Geo Metro from 1990 to 1997 with a 1.0L or 1.3L engine and need to replace the distributor, here's how to do it. Access to the distributor is easy, and you don't need to buy special tools.

Instructions

1

Look for the distributor on the right side of the engine block as you face the engine compartment; it's easy to spot because of all the spark plug wires leading to it. Disconnect the negative cable from the battery.

2

Tag each spark plug wire, and disconnect them from the distributor, as well as removing the wiring harness with a screwdriver and unhooking the vacuum line at the distributor, if your Metro has one. Use a screwdriver to remove the distributor cap.

3

Make a mark to show the position of the distributor rotor relative to the distributor body; likewise mark the position of the distributor body to the cylinder head. Also mark the distributor's position pertaining to the housing and engine. You'll use these marks later in re-installation.

4

Use a wrench to unbolt the hold-down bolt or bolts, depending on your model year, and lift the distributor out of the cylinder head. Avoid moving any engine parts after the distributor has been removed, or re-installation will be more complicated. Remove the O-ring from the distributor shaft.

5

Put in a new O-ring, oiling it lightly. Before inserting the new Metro distributor, line up all the marks made during removal. Position your Metro distributor carefully and as you install it, make sure the drive gear engage properly within the slot. The part number is 84170N for a distributor from Parts Train, with the O-ring a separate order.

6

Use a wrench to install the hold-down bolts on the distributor lightly. Reconnect the wiring and the plug wires. Connect vacuum hoses, if so equipped.

7

Install the distributor cap and screw it on. Connect the battery negative cable. Tighten the distributor hold-down bolt or bolts.
