Check your owner’s manual. Cadillac Northstar engines use two or three timing chains. But, I don’t know if they have service intervals. Your owner’s manual will state if so.

That is because you have timing chains and they normally do not need to be replaced.

Is it a V8 Northstar? That Lotus designed engine uses chains. The older pushrod engines also use a timing chain with no service requirement.
