Yes, you can spray carb cleaner into a turbo, but the method and timing are critical and depend on whether the engine is running.
When the Engine is NOT Running
If your engine is not running, it is generally advisable to spray a foaming carburetor cleaner directly into components such as the turbo, throttle body, or EGR (Exhaust Gas Recirculation) valve. This allows the cleaning product sufficient time to penetrate and break down carbon deposits and grime effectively without the operational risks associated with a running engine.
When the Engine IS Running
Spraying typical foaming carburetor cleaner directly into a turbo when the engine is running is generally not recommended. Foaming products can create issues or risks within a running engine's system if introduced directly.
However, if you are unable to remove components for cleaning while the engine is in operation, an alternative method involves using a suitable carburettor cleaner, such as Wynns Carburettor cleaner, by spraying it into the air stream after the air filter. This approach allows the cleaner to atomize and circulate through the system with the airflow, potentially helping to clean the turbo and even the EGR valve indirectly.
Summary of Carb Cleaner Application to Turbo
| Engine Status | Recommended Method | Notes |
|---|---|---|
| Not Running | Spray foaming carburetor cleaner directly into the turbo. | This is the optimal time for foaming products to effectively clean carbon deposits on the turbo, throttle body, and EGR valve without operational risks. |
| Running | Avoid spraying typical foaming cleaners directly. | If parts cannot be removed, spray a suitable cleaner (e.g., Wynns Carburettor cleaner) into the air stream after the air filter. This allows for indirect cleaning while the engine is in operation. |
Always ensure you are using the correct type of cleaner for your vehicle and application, and carefully follow the product's instructions to prevent any potential damage.
