Delco Remy 35SI™ Heavy Duty Brushless Alternator
The Delco Remy 35SI heavy duty alternator, designed for high-underhood-temperature EGR and ACERT* engines, features heat dissipating radiant vents and thermally tolerant internal components that ensure high output in environments up to 105°C / 221°F. The 35SI features a brushless design with fewer moving parts and internal connections, resulting in consistently superior performance and contamination resistance and longer product life compared to traditional brush-type alternators.

The Delco Remy 35SI brushless alternator design dramatically increases both the durability and the life of the alternator.
Here’s why: Brushless alternators have fewer moving parts, which means less wear on the alternator. The end result is longer life. Alternators pull air from the back to the front in order to cool the internal electronics. This process introduces contaminants to the alternator. With a brushless alternator, there are no issues of contaminants hanging up brushes and causing failures. Without brushes, there are 13 fewer moving parts, eliminating components that wear out.
Bottom line: Delco Remy’s 35SI brushless alternator design leads to reduced downtime and longer life.
Remote Sense can reduce battery charge time by 50%. Some 35SI models are equipped with Remote Sense which utilizes a second wire that reads the actual to boost its output to compensate for the voltage drop, ensuring 14 Volts at the battery. The proper voltage forces more current into the battery bringing it to a full state of charge between vehicle stops.
The Delco Remy 35SI alternator has demonstrated it has the power you need to meet increasing electrical demands.
