What are the costs to replace the engine in a 2002 Highlander?

The cost to replace a 2002 Toyota Highlander's engine can vary depending on which part of the country You're from; You're typically not going to find a new engine, but rather find a "donor" engine from somewhere like a junkyard. Because of this, prices can fluctuate quite a bit, but most would say that the fair range is between $700 for a used engine alone, and $3,500 for parts and installation (labor). It's also important to ask what components You'll be getting with the new engine. A swap is typically more seamless and quicker if You get ahold of several related components; this can also save You some headache down the road. Overall, Your experience with engine swapping is going to vary greatly; just don't let anyone take advantage of You, and know when to say no if the procedure is going to cost You more than the value of the Highlander.
