Engine Assembly: Inspection
WARNING: This page is about a different car, the 2023 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
INSPECTION AFTER INSTALLATION
- Check wheel alignment. Refer to Inspection .
- Adjust the neutral position of the steering angle sensor. Refer to Description .
Inspection for Leakage
The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.
- Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to Fluids and Lubricants .
- Use procedure below to check for fuel leakage.
- Place ignition switch in the "ON" position (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
- Run engine to check for unusual noise and vibration.NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may generate a pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise will stop after hydraulic pressure rises.
- Warm up engine thoroughly to check there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.
- Bleed air from lines and hoses of applicable lines, such as in cooling system.
- After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.Summary of the inspection items:
