Aeagle Starter for Cadillac Escalade 5.7L 1999-2000 — 11-Tooth PG260L OE-Fit, Bench-Tested

This compact starter assembly is built as a one-to-one fit for numerous GM platforms from the mid-1990s through the early 2000s. Designed and factory-tested by Aeagle, the unit replicates OE mounting, gear count, and electrical connections so you can return a stalled or slow-turning engine to dependable starting without costly modifications. The listing specifies an 11-tooth pinion (PG260L series) — do not use for 9-tooth applications.

Which vehicles does this starter fit?

The Aeagle 6449 fits many Chevrolet, GMC, Cadillac, Oldsmobile and Isuzu models over a broad range of years and engine sizes. Compatibility covers small SUVs, full-size trucks, passenger vans and work trucks using 4.3L through 8.1L engines where an 11-tooth starter is required.

• Cadillac Escalade 5.7L: 1999–2000
• GMC Savana series and Chevrolet Express: multiple 5.0L, 5.7L, 7.4L and 8.1L model years

• Older S-series and compact GM vehicles such as Astro, S10, Jimmy, Bravada, and Isuzu Hombre where listed

How does this replacement compare to original equipment?

Aeagle's 6449 starter is manufactured to match OE mounting points, electrical terminals and pinion tooth count so installation and performance mirror the factory unit. Each starter is computer-tested to ensure consistent output and reliable engagement under typical starting loads.

• Exact 11-tooth pinion for correct ring gear mesh
• OE-style mounting flanges and bolt hole pattern for bolt-on installation
• Standard electrical terminals compatible with factory wiring harnesses
• Bench-tested units for verified starting torque and solenoid operation

What part numbers and series does it replace?

This starter replaces a variety of legacy GM OEM and aftermarket part numbers used across platforms. The listing is explicit that the unit is the 11-tooth PG260L series, not the 9-tooth option, so confirm pinion count before ordering.

• Cross-references: 10465578, 19136219, 330001419 and many legacy GM IDs
• Also replaces aftermarket references such as 410-12153, 410-12407 and SDR0019 variants
• Sold as an 11-tooth PG260L replacement — verify against your old starter

What should I check before buying or installing?

Confirm your vehicle’s engine displacement, year, and the tooth count of the original starter pinion. Inspect the mounting pattern and electrical connector on the old part to ensure this Aeagle unit is the correct match. If you’re unsure, compare one of the cross-reference part numbers or consult a professional mechanic.

• Verify 11-tooth pinion (this product is NOT for 9-tooth applications)
• Match engine size and model year against compatibility list
• Compare mounting bolt pattern and terminal type with the old starter
• Keep original hardware and follow torque specs during installation

Who is this for: Mechanics, fleet maintenance teams, and DIY owners working on late-1990s to early-2000s GM trucks, vans and SUVs who need a cost-effective, tested replacement starter. If your vehicle requires an 11-tooth starter and shows slow cranking, grinding, or no-crank symptoms, the Aeagle 6449 provides a reliable, OE-style swap to get engines turning again with straightforward installation.
