What's the replacement cost for a 2002 GMC Envoy engine ?

The cost for an engine swap on a 2002 GMC Envoy largely depends on whether You want a new engine, or if You'll accept a junkyard one. Reports of "preowned" engines for the '02 Envoy typically place it around $500 to $800 for something with around 100,000 miles. On the other hand, You'll be looking to pay about $3,000 in parts alone if You want to opt for the new. If You want to undertake the job Yourself, expect it to last a week or more if You're working alone. If You have good help, it's possible to do an engine swap over a long weekend.
