Addressing concerns about high underhood temperatures associated with low-emissions engines, Delco Remy has introduced the 36SI HP premium brushless alternator. It’s said to satisfy rising vehicle electrical system demands with ultra-high power output, increased fuel efficiency, and superior resistance to high operating temperatures. The 36SI HP is rated at 170 amps at highway speed and 100 amps at idle in ambient temperatures of up to 105ºC.

The 35SI and 36SI product families incorporate the company’s premium ‘Flex-Lead’ bridge design and higher-capacity, press-fit diodes, which are well suited to applications with higher underhood temperatures and increased vibration within the engine compartment. The new bridge design is 40 times more resistant to vibration and offers six times the amount of heat-dissipating surface area than conventional bridge and diode designs.

The 36SI HP features improved electrical efficiency that helps reduce required operating horsepower, resulting in improved engine efficiency and lower fuel cost. It’s backed by a free extended warranty of three years/350,000 miles on new service units, and two years/250,000 miles on genuine Delco Remy remanufactured units.
