Part Quality Checklist

Take these precautions to verify that parts are functional before purchase:

• Inspect Oil Condition: Look under the oil filler cap for milky residue, which indicates head gasket failure.
• Compare Engine Codes: Verify casting codes (e.g. 5.3L LH6 vs LM7) to avoid complex wiring harness mismatching.
• Check Transmission Fluids: Drain a small sample of fluid—avoid units showing burnt smell or metal flakes.
• Decode Vehicle History: Use our VIN lookup tool to check model specs and ensure parts match.
• Sell Unwanted Cars: If your car is beyond salvage, you can also sell your junk car for cash directly.
