Location of the Thermostat in a 2006 Chevy Uplander
The thermostat in a 2006 Chevy Uplander is located on the lower, passenger-side corner of the engine. If you have the 3.5-liter engine, it is located just above the air conditioning compressor. If you have the 3.9-liter engine, it is almost in the same location, but directly above the oil filter housing. The process for either engine is the same. It’s important to properly fill and bleed the cooling system to complete the repair.
If you’re changing the coolant and the thermostat in a 2007 Chevy Uplander 3.9 liter engine, the thermostat is located on the engine either at the inlet or outlet radiator hose connections and is part of the cooling system. This unit is designed to stop the flow of coolant from the engine to the radiator.
A malfunctioning thermostat can cause the engine to heat up slowly or not at all, affecting the engine’s performance and the heater. If the thermostat doesn’t open or won’t stay open, the coolant won’t move to the radiator, and the engine will overheat, potentially causing damage to gaskets and internal engine parts.
The thermostat replacement cost for a Chevrolet Uplander is estimated to be between $663 and $723 on average.
I hope this information helps you locate and understand the thermostat in your 2006 Chevy Uplander!

Can a bad thermostat cause an engine to overheat?

Overheating is the most common symptom of a failing thermostat. Due to corrosion or aging, your car’s thermostat can get stuck in a closed position. If this happens, the thermostat will not let the coolant reach the radiator, and, as mentioned above, the engine will overheat, causing severe damage.

Where is your thermostat located?

Ideal Thermostat Placement
The best place for your thermostat is on an interior wall, away from all the areas we previously discussed (direct sunlight, air vents, your kitchen, hallways, windows and doors). Ideally, it should be placed toward the center of your home.

Is my car overheating or is my thermostat bad?

If it continues to read too cold or registers too hot, then there is the chance that the temperature gauge should be replaced.

How do you test a car thermostat without removing it?

There are several ways to check the health of your car’s thermostat and you don’t necessarily have to remove it: observing the coolant flow or measuring the temperature of the upper and lower radiator hoses with an infrared thermometer. Check if the thermostat is stuck closed.

How do I know if I have a bad thermostat?

A bad thermostat can be detected when your AC or furnace is not turning on, your HVAC systems are not turning off, the thermostat not responding, your HVAC system is short-cycling, the room temperature not matching the temperature displayed on the thermostat, and the programmed setting resetting themselves.

How do you tell if a thermostat is stuck closed?

If you see the coolant flowing through the radiator, then the thermostat opened and is working properly. If not, then it is most likely stuck closed. If you can’t tell if the coolant in the radiator is flowing, shine a flashlight inside so you can see it better.
