Where is thermostat on 3.4 liter engine located?

There's no single answer to where the thermostat is located on a 3.4L engine. The location varies significantly depending on the *make* and *model* of the vehicle. The 3.4L engine was used in many different cars and trucks over the years by different manufacturers (Toyota, GM, etc.) Each had its own unique design.

To find your thermostat, you'll need to:

1. Identify your vehicle: Know the make, model, and year.

2. Consult a repair manual: A repair manual specific to your vehicle will show you exactly where the thermostat is located and provide step-by-step instructions for replacing it. You can usually find these online or at auto parts stores.

3. Search online: Search online using your vehicle's make, model, year, and "thermostat location." You might find pictures or videos showing its location.

Without knowing the specific make and model of your car, it's impossible to provide a precise location.
