WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- When using high-pressure water or steam cleaning equipment, to avoid the risk of personal injury from flying debris and hot steam:
- Wear appropriate eye protection and protective clothing including gloves and a face shield.
- When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
- Do not exceed 207 kPa (2.111 kg/cm 2 , 30 psi).
- Wear appropriate eye protection and protective clothing including gloves.
- Clean the exhaust manifold with solvent and dry with compressed air.
- Inspect the exhaust manifold for cracks or other damage.
- If damage is found, the exhaust manifold must be replaced. NOTE: If the exhaust manifold is damaged, check for charge-air leaks. A charge-air leak can cause progressive damage to the exhaust manifold.
- Inspect the exhaust manifold heat shield for cracks.
- Replace the heat shield if damage is found.
- Use a suitable tool (A) to check the exhaust manifold (1) mounting surfaces for flatness.
Limit
: Refer to EXHAUST MANIFOLD .
- Lay the suitable tool on the edge across all ports and measure the flatness with a feeler gauge.
- If any port measures out of specification, replace the exhaust manifold.
