General Information

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.

CAUTION: To avoid possible chain damage, loosening and tighten camshaft, oil pump and fuel pump sprocket bolts with the aid of the spanner wrench.

It is very important to avoid loading the chain while loosening and tightening the bolts on the camshaft, fuel and oil pump sprockets. Always hold the sprockets with a suitable tool (A) when loosening or tightening the bolts with a suitable tool (B).

NOTE: If there is a lack of tension on the fuel pump or camshaft timing chains after removing the front cover, this does not indicate chain tensioner failure. The chain tensioners are fed oil pressure to keep tension on the chains. During removal, the chains may not be under full tension, this does not warrant replacement.
