Important information regarding assembly
A turbocharger is not specific to a specific car model. Selection requires verification of the dimensions, flanges, connections, and parameters of the turbocharging system in a given vehicle. Professional installation is recommended.
- Before installing a new turbocharger, the cause of the failure of the previous one must be determined and eliminated, e.g. insufficient lubrication, a foreign body in the intake system or faulty crankcase ventilation.
- The oil return line should be located lower than the turbocharger.
- In a petrol vehicle, a water cooling system must be used in accordance with the installation requirements.
- The exhaust outlet should be tightly connected by welding.
- The air filter element must be replaced, repaired or reconnected according to the manufacturer's instructions to reduce the risk of damage to the compressor wheel.
