TadaMark Starter for GM Trucks & Vans — 11-Tooth CW PMGR, Without Heat Shield, 12V High-Torque

High-torque 12V PMGR starter for select GM trucks and vans (1994–2002), 11-tooth CW rotation, built to replace common OE numbers without the heat shield.

This TadaMark starter is engineered to restore reliable cranking to a long list of General Motors V6 and V8 engines. Designed as a direct-replacement PMGR (permanent magnet gear reduction) starter, it matches the OE bolt pattern, electrical connections and 11-tooth pinion required by many Chevy, GMC, Cadillac and associated platforms from the mid-1990s through the early 2000s. The unit ships without a heat shield and is specified for clockwise rotation with a 1.6 kW rated motor.

How do I confirm this starter replaces my original part number?

Compare the OE number stamped on your existing starter or check your parts catalog against the replacement list provided. TadaMark includes many commonly used GM part cross-references so you can match fitment before purchase.

• Common replaceable part numbers included in the list (e.g., 10465554, 12560019, 3361910A)
• Also cross-references legacy OEM codes like 281-8002 and 323-1459
• Verify pinion tooth count (11) and rotation direction (CW)
• Confirm bolt pattern and electrical connector type on your vehicle

Are there installation considerations since it ships without a heat shield?

Because this starter is supplied without a heat shield, check your vehicle’s original configuration to determine whether a shield is required or if the engine bay already provides sufficient clearance. Standard installation follows OEM torque and grounding practices for reliable operation.

• Inspect surrounding components for clearance and routing of wires
• Use correct torque values for mounting bolts to avoid misalignment
• Reconnect battery and verify starter engages and cranks smoothly
• If original used a shield, consider reusing it or fitting equivalent protection

Who is this for: Mechanics, fleet managers and do-it-yourself owners working on mid‑1990s to early‑2000s Chevrolet, GMC and Cadillac trucks, vans and SUVs who need a reliable, direct-replacement PMGR starter. It’s suitable when OE part numbers match the cross-reference list and when an 11-tooth, clockwise starter without a heat shield is acceptable for the vehicle’s installation.
