Premier Lexus Repair Services in Jackson

Water Pump Failure

The water pump pushes the coolant to circulate throughout the engine, enabling the cooling process. A malfunction in the water pump can cause severe engine overheating, leading to head gasket failure, warped cylinder heads, or complete engine seizure. The primary causes behind its malfunctions are;

• Age-induced wear and tear in old bearings and seals.
• Corrosion due to old or incorrect coolant type.
• Degradation of plastic impales, found in some old designs.

Diagnostics and Repair: The diagnosis at our shop in Jackson includes visual inspection, pressure test to identify leaks, stethoscope check, and temperature monitoring.

The repair process starts with removing engine covers and components to gain access to the water pump. The engine’s old coolant is safely drained, and the damaged water pump is carefully removed. The mating surface on the engine block is thoroughly cleaned, and a new, high-quality Lexus or OEM-equivalent water pump is installed.

This is followed by reassembling and coolant refilling. Here, a crucial procedure is done at Automotive Perfection in Jackson, called bleeding, where any remaining air bubbles are removed from the system.

VVT-i System Malfunctions

Lexus features Toyota’s Variable Valve Timing with intelligence (VVT-i) system, which optimizes valve timing for improved performance, fuel economy, and emissions. Malfunctions in this system affect engine efficiency and performance, causing a rough idle, fuel inefficiency, and increased emissions. The underlying causes behind it are;

• Clogged oil control valves
• Faulty VVT-i actuator/sprocket,
• Low or contaminated engine oil, and
• Electrical Failure

Diagnostics and Repair: Lexus-specific scan tools are used at Automotive Perfection in Jackson to accurately read DTCs, analyze live data, and determine the origin of the malfunction. Additionally, visual inspection, OCV testing, oil pressure testing, and engine oil condition checks are also performed.

Our technicians in Jackson provide accurate repairs based on the findings from the diagnosis of the malfunction. This includes OCV replacement, engine oil flush/change, and VVT-i actuator/sprocket replacement. After the repairs are completed, the malfunction codes are cleared, and a test drive is conducted to verify the effectiveness of the repair.

Suspension Malfunction

When crucial suspension components, such as struts, shocks, or bushings, malfunction or wear out, the ride quality and handling are degraded, causing suspension malfunctions in Lexus. This results in a harsh ride, creaking noise, uneven tire wear, poor handling, and leaking struts. The factors behind this malfunction are;

• Normal wear and tear
• Accelerated component degradation due to bad driving conditions
• Age-induced corrosion in rubber bushings and fluid-filled struts

Diagnostics and Repair: Our technicians at Automotive Perfection in Jackson perform visual inspections, bounce tests, road tests, and alignment checks as part of the diagnostic procedure.

Depending on the malfunction, components such as struts, shock absorbers, control arm bushings, or sway bar links are removed using specialized tools at our shop in Jackson. In their place, new, genuine Lexus or high-quality OEM-equivalent components are installed. This often includes new mounting hardware, boots, and bump stops with struts.

The torque specification and reassembling follow this. Then, a wheel alignment service is conducted, as it is absolutely critical after suspension services to ensure correct steering geometry, optimize tire wear, and restore handling.
