Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failing control unit may be intermittent engine performance issues or illuminated dashboard warning lights. If ignored, these issues can become more persistent, leading to reduced power and increased fuel consumption. Left unaddressed, a faulty ECU can prevent the engine from starting or cause it to stall unexpectedly.
Before replacing the ECU, ensure the battery voltage is stable and disconnect it to prevent electrical surges. Avoid forcing connectors into place, as this can damage the pins and lead to further electrical problems.
Inspect the engine wiring harness and associated sensors for any signs of damage or corrosion before installing the new control unit.
