How to Replace the Starter on a 2009 Nissan Altima. The quick answer is below, then the longer procedure, parts, and factory references.
Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Quick answer
Starter jobs start with the no-crank diagnosis
This page keeps the click/no-crank symptom, battery follow-up, and access steps near the top so owners can decide quickly if the starter is the real problem.
Direct answer
Confirm the starter before you order
2009 Nissan Altima starter jobs are usually decided by symptom pattern, battery health, and access path.
- • Starter part: Starter motor
- • Use the click/no-crank symptom before replacing the starter.
- • Check battery condition, wiring connections, and the mounting area first.
- • Plan for under-vehicle access on many layouts and clean the mounting surface for a strong ground.
Before you order
Match the starter fitment and access path
Starter access is labor-heavy on many vehicles, so verifying engine and transmission fitment first saves the most wasted time.
- • Match engine and transmission before checkout.
- • Confirm mounting ear count and electrical terminal layout.
- • Plan access first because this job often starts under the vehicle.
Next step
Keep the battery and charging pages nearby
A weak battery or charging system can mimic a starter problem, so the follow-up pages matter here.
- • Use the battery page if the symptom started after low voltage or a dead battery.
- • Use the alternator page if the charging light or battery warning is part of the story.

2009 Altima 2.5L starter — 1.4kW, rear bellhousing mount, driver side
The 2009 Nissan Altima (L32) with the QR25DE 2.5L 4-cylinder has the starter mounted on the driver side of the transmission bellhousing, tucked behind the intake manifold. Access is best from above with the air cleaner assembly removed.
Starter rating: 1.4kW — Hitachi S114-902 or Valeo TS22E10; 9-tooth pinion for QR25DE flywheel; verify clockwise rotation
Mounting: upper 14mm bolt (long, through starter nose) and lower 12mm bolt (short, into bellhousing ear) — upper bolt is behind intake manifold runners
Access: remove air cleaner box (one 10mm hose clamp, two 10mm bolts, MAF connector), remove battery negative first, then move harness aside
B+ cable: 12mm nut under rubber boot — wrap terminal in tape before removal to prevent short against intake manifold heat shield
Solenoid trigger: small spade connector with locking tab — squeeze tab, pull straight off; do not pull wire, pull connector body
Torque upper 14mm bolt to 33 ft-lb, lower 12mm bolt to 17 ft-lb — both into aluminum bellhousing; no threadlocker needed if clean and dry
After install: reconnect battery, crank engine — if starter drags, check battery voltage (must be 12.4V+); QR25DE starters draw 150–180A cold cranking
