My daughter has a 2001 Nissan Sentra with the 1.8L engine. Does this engine have a timing belt or timing chain? The concern is that if it is a belt, it should be replaced soon (100,000+ miles).
And, is it the design such that if has a belt and the belt fails, the engine does not get damaged (destroyed)?
Thanks,
Dave C.
If it's the QG18DE engine, then it's a chain, not a belt.
You don't need to do that much research. All Nissan 4 cylinder engines since about 1990 use timing chains. The last belt they used was in the first version of the V6 quest minivan and that is now a chain as well.
