What is the rear differential fluid capacity of a 2019 Chevy Colorado?
The rear differential on a 2019 Chevy Colorado typically holds about 2 quarts of gear oil. For most models, the fill volume centers around two quarts, though the exact amount can vary slightly depending on the axle configuration. Always verify the precise specification for your truck in the owner's manual or on the axle tag.
Understanding the capacity requires noting that the Colorado offered two rear-axle configurations: the standard 8.6-inch axle and, in the ZR2, a larger Dana rear axle. While both configurations generally fall near the two-quart mark, the exact drain-and-fill quantity should be confirmed from official documentation or the vehicle’s axle tag. This article summarizes typical figures and best practices for maintenance.
Axle configurations and capacity expectations
Below are the general expectations for rear differential capacity on the 2019 Colorado. Use these as a guideline, and verify against your specific vehicle to ensure accuracy before servicing.
- Typical capacity for most 2019 Colorado rear axles: about 2.0 quarts (roughly 1.9–2.1 qt, depending on the exact axle model).
- ZR2 configuration (Dana rear axle) capacity: generally in the same 2.0-quart range, but always confirm the exact amount from the axle tag or GM service data.
Concluding this section, plan on having approximately two quarts of gear oil on hand when performing a drain-and-fill. Exact figures should be confirmed using the vehicle’s axle tag or the official service documentation.
Lubricant type and refill procedure
Proper lubrication hinges on using the correct gear oil and following the fill level guidance. Here are the key points to keep in mind.
- Oil specification: Use 75W-90 synthetic gear oil that meets GL-5 specifications, as recommended for typical GM rear axles. Always check the owner’s manual or GM service data for the exact spec for your axle.
- Limited-slip considerations: If your rear axle is equipped with a limited-slip differential, include the appropriate friction modifier as directed by the oil manufacturer or GM guidelines.
- Refill procedure: After draining, clean the drain and fill plugs, replace any gaskets as needed, and refill to the correct level as indicated by the fill plug or the owner’s manual. Avoid overfilling, which can cause foaming or leakage.
Bottom line: using the recommended gear oil and adhering to the specified fill level helps ensure proper lubrication and longevity of the differential.
Summary
The 2019 Chevy Colorado’s rear differential capacity is typically around 2 quarts, with slight variation by axle type. Always confirm the exact figure from the owner’s manual or the axle tag before servicing, and use the recommended gear oil (75W-90 GL-5) with any necessary friction modifier for limited-slip units. Following the proper refill procedure helps protect the differential and prolong its life.
