Volvo XC90 Supercharger Reseal

Volvo XC90 Supercharger Resealing Repairs in Seattle

The second-generation Volvo XC90 T6 is the family vehicle to rule them all, offering a comfortable, safe mode of transportation that can still overtake any other car on the freeway. The engine necessary to achieve this feat is the B4204T27, which is a 2.0 liter, twin-charged, four-cylinder motor, meaning it is equipped with both a turbocharger and supercharger. This innovative design delivers exceptional power and efficiency by eliminating the dreaded “turbo lag,” which is the delay in acceleration experienced as the turbocharger spools up before supplying compressed air to the engine. However, one common issue on this engine is that the supercharger system tends to leak air and/or oil as the supercharger housing plastics warp with heat and age. In these cases, the only solution is to replace the leaking parts and reseal the supercharger system. 

The Role of the Supercharger in Your Volvo

In the XC90 T6’s twin-charged system, the supercharger plays a critical role. Unlike the turbocharger, which uses exhaust gases to produce additional power, the supercharger is mechanically driven by the engine’s crankshaft. This allows it to deliver instant boost at lower RPMs, ensuring consistent power delivery and smooth acceleration. However, many of the air pipes and housings for the supercharger system are made of either rubber or a glass-reinforced nylon fiber material that is subject to wear and tear and, of course, subsequent leakage.

Symptoms of a Leaking Supercharger

It is critical to be aware of the symptoms of a leaking Volvo XC90 supercharger. If any of the following symptoms are detected, it’s time to bring your vehicle to Precision Motorworks for a professional inspection. Most commonly, Volvo XC90 owners will notice a “Check Engine” light appear on the dash in tandem with reduced performance and lacking engine power. There are many sensors throughout the forced induction system that detect even the slightest changes in air pressure, temperature, and vibration. If a malfunction is detected, fault codes will trigger in the Engine Control Module (ECM) and a check engine light will appear. Additionally, it is not unusual to see oil leakage on the ground or low oil levels present when the supercharger area leaks. It is vital to be aware of the oil level inside the engine and to periodically check the floor for any signs of oil drips. 

Why Prompt Repairs Are Essential

When a supercharger leaks, especially in a twin-charged system, other areas of the engine begin to wear as well. For example, fuel injectors will often over-exert themselves when air is leaking from supercharger housing pipes and oil often leaks into areas it does not belong, resulting in contamination of various engine components.
