Continental 40012 Engine Timing Belt

Continental 40012 Engine Timing Belt

The Continental 40012 engine timing belt is built for precise valve train synchronization in compatible applications. It uses EPDM construction with trapezoidal teeth to maintain consistent engagement with cogged components, while the belt profile is engineered for stable contact and long service life.

Key Features

• EPDM material for resistance to heat, abrasion, and ozone exposure
• Precision-molded trapezoidal teeth for accurate cog engagement
• 91 belt teeth for timing accuracy in the specified application
• 1.000-inch top width and 45.500-inch belt length
• No timing marks

Product Details

Continental 40012 is an engine timing belt designed for vehicles that require a 91-tooth, trapezoidal-tooth belt with a 1.000-inch top width and 45.500-inch length. The EPDM belt construction helps resist shrinking and elongation, which supports consistent timing performance over time. This part number is used in select 1975-1977 Chevrolet Monza, 1976-1977 Oldsmobile Starfire, and 1976-1977 Pontiac Sunbird applications. This part cross-references Hella 912 for the same application.

What It Helps Address

• Timing belt wear from heat and ozone exposure
• Loss of belt tension caused by elongation
• Inconsistent tooth engagement with cogged pulleys
• Valve timing issues related to belt deterioration
• Noise or drivability concerns tied to worn timing components

Installation Notes

Verify tooth count, belt length, and width against the original belt before installation. Because this belt has no timing marks, alignment should be confirmed using the engine’s service procedure and timing references. For 1975-1977 Chevrolet Monza, 1976-1977 Oldsmobile Starfire, and 1976-1977 Pontiac Sunbird applications, confirm engine configuration and pulley alignment before final assembly. Continental 40012 should be installed as part of a complete timing system inspection when wear is present on related components.

Quality Assurance

Continental uses premium polymer construction and precision-molded tooth geometry to support durable timing belt performance in demanding engine environments.
