Secure Transaction

Your payment info is protected at all times.

Cross-referenced parts are cataloged as fitting the same application but are not guaranteed to be identical to the original manufacturer part. Verify fitment against your OE number or VIN before ordering.

How to Confirm This Part Fits Your Vehicle

Reference/cross-reference numbers vary by engine, transmission, chassis and production date — not by number alone. Before ordering, compare your original OE number against 3L8666 number by CATERPILLAR listed above, and check the dimensions or specifications against your original part.

If you’re unsure, contact CarBus24 with your VIN or the number printed on your original part and we’ll confirm the correct match before you order.

Frequently Asked Questions

How do I know if a part matching 3L8666 number by CATERPILLAR fits my car?

Compare your original OE number against the OE Reference Numbers listed above, and check the dimensions or specifications against your original part.

What is the difference between OE and aftermarket parts?

OE parts match the original manufacturer specification. Aftermarket parts are cross-referenced to fit the same application, usually at a lower price.

Can I search by my vehicle instead of an OE number?

Yes — select your vehicle from the sidebar to see parts confirmed to fit your car.

What if I'm not sure which OE number I have?

Send us your VIN or the number printed on your original part and our team can confirm the correct match before you order.
