Expert Engine Repair for Swedish Auto Owners in Austin

Timing Chain Tensioner Failure

The timing chain tensioner is responsible for maintaining a properly secured timing chain, which should be precisely aligned with the engine. It usually compresses the chain to prevent it from getting loose or slipping off its track, ensuring the engine valves open and close at the correct time so that the entire engine can function seamlessly and effectively. However, neglecting regular oil changes at recommended intervals, using low-quality oil, or experiencing some inherent faults can eventually cause the timing chain tensioner to malfunction, impacting overall engine efficiency and performance. As a result, your car starts showing warning signs, such as a strange rattling noise from the engine compartment, especially when the ignition is on, poor engine operation, or a glowing or flickering check engine light on the dashboard.

Regardless of the situation, please reach out to our repair hub located near Austin, TX, and let us inspect the timing chain and tensioner for any signs of physical or internal damage. If we identify any ongoing issues, we will consider replacing both components with new, upgraded parts. This will be followed by draining the old oil and replenishing the engine with premium-quality oil, thereby restoring peak engine performance. You can also contact us regularly for routine oil changes, as specified in the manufacturer’s manual, to prevent further engine complications.

Carbon Deposits on Intake Valves

In simple terms, the intake valves are engineered like doors that open and close at the correct intervals to pass the right amount of air-fuel mixture into the combustion chamber, allowing for optimal combustion and subsequent ignition. This way, the fuel is directly injected into the combustion chamber without coming into contact with the intake valves, thereby preventing the accumulation of carbon and other deposits from the crankcase ventilation system on them. This not only causes rough idling and engine misfires at low RPM but also results in high fuel consumption due to improper engine operation and reduced power.

Experiencing any of the above issues? Feel free to reach out to our auto shop near Austin, TX, so we can safely use the walnut blasting method to remove the carbon buildup formed on the intake valves. The process typically involves blasting crushed walnut shells into the intake ports to thoroughly clean both their internal and external areas, restoring optimal engine performance and enhancing your vehicle’s fuel efficiency.

Water Pump Troubles

The primary role of the water pump is to distribute the liquid coolant evenly throughout the engine’s cooling system, preventing the entire engine from overheating, maintaining an ideal temperature in its compartment, and providing a calm environment for the internal engine parts to function at their peak. However, the plastic impellers used in most European cars wear out over time due to aging and frequent usage, and start showing various abnormalities, such as excessive heat generation, coolant leaks, or odd grinding sounds coming from the front part of the engine.

Do you think the faulty water pump is the real culprit? If so, please connect with our professionals at our garage near Austin, TX, as we can verify whether the water pump is malfunctioning and replace it immediately with an all-metal impeller version for enhanced durability and improved performance. Next, we can also perform a pressure test to spot leaks or weak hoses in the cooling system. Identified leaks will be sealed, and faulty hoses will be replaced to get everything back on track.
