How to Prime a Turbocharger Using Pre-Lubricant

Turbochargers are essential for boosting engine performance, but they require proper lubrication to function efficiently and avoid premature failure. One critical step before starting a newly installed or rebuilt turbo is priming it with pre-lubricant. This ensures the bearings and oil passages are properly lubricated, preventing dry starts that can cause damage.

In this guide, we’ll walk you through the steps to properly prime your turbocharger using pre-lubricant.

Why Priming a Turbocharger is Important

A turbocharger spins at extremely high speeds (up to 150,000 RPM or more). Without proper lubrication:

• Metal-on-metal contact can occur, damaging bearings.

• Heat buildup from friction can warp or seize components.

• Premature failure leads to costly repairs or replacements.

Priming ensures oil flows through the turbo before the engine starts, protecting critical parts.

Tools & Materials Needed

• Pre-lubricant (turbo-specific oil or assembly lube)

• Oil can or syringe (for precise application)

• Clean lint-free cloth

Step-by-Step Guide to Priming a Turbocharger

Step 1: Remove the oil feed line (if the turbo is not yet installed)

Step 2: Apply a small amount of pre-lubricant directly into the oil inlet port of the turbo.

Step 3: Manually rotate the turbine wheel to help distribute the oil inside the bearing housing.

Additional Tips for Turbo Longevity

✅ Always use high-quality synthetic oil (turbo-specific if recommended).
✅ Allow the turbo to cool down after hard driving (avoid immediate shutdown).
✅ Regular oil changes prevent sludge buildup in the turbo.

Final Thoughts

Priming your turbocharger with pre-lubricant is a simple yet crucial step to ensure longevity and performance. Skipping this process can lead to catastrophic failure, so take the extra time to do it right!
