Nissan Pulsar 1990 Problems

THE factory radiator is the way to go. They can be had for about $180, which is cheap, and they're the best. Nissan service specialist Jerry Newman says electrolysis is usually caused by a stray electric current, probably as a result of a bad earth somewhere in the car. But he says it rarely occurs if you use the correct coolant at the correct level.

MY INFORMATION says the Pulsar GL has single-point fuel-injection, not a carburetor, so I'm not sure what adjustments the mechanic made. I would be checking the electronic sensors, specifically the oxygen sensor, that control the air/fuel ratio.
