This is the electric brake booster vacuum pump — used on 3.6L Pentastar V6 engines that don't generate enough intake manifold vacuum to operate the brake booster on their own. The pump runs continuously as needed to maintain vacuum reserve for brake assist. Electronic/mechanical component — mounted via rubber isolator bushings to reduce noise/vibration, powered through a 2-pin electrical connector. A common failure point on these Pentastar-equipped vehicles (loss of vacuum → hard brake pedal / warning light).
Compatible With:
Chrysler/Dodge/Jeep 3.6L Pentastar V6
- 2011-2021 Jeep Grand Cherokee (WK2) 3.6L
- 2011-2023 Dodge Durango 3.6L
(Confidence 90%+ for these two based on confirmed cross-reference listings for P04581954AB / UP32. This vacuum pump design was also used on other 3.6L Pentastar-equipped Chrysler/Dodge/Jeep/Ram models — Chrysler 300, Dodge Charger, Ram 1500 — but exact part number/revision (UP30 vs UP32) can differ by model year and trim; confidence for those is below 90%, so verify against your OEM part number/VIN before purchasing.)
