What causes temperature fluctuations in a Chevy Venture?

The most likely cause of a temperature fluctuations is either a flauty temperature sending unit , air in cooling system or a defectective cooling fan . If the engine temperature is stable when driving at highway speed and temperature rises when idling or in traffic , the fan is the cause .

Where is the temp sensor on a Chevy Venture?

Some thermostats can be put in upside down, so pay attention to the arrows on the thermostat. The water should flow from the engine towards the radiator. The temp sensor I think is in the rear passenger side of the engine on top.

Why is the thermostat on my Chevy Venture not working?

Pam, your problem seems similar to the original question. If the engine’s temperature will not stabilize around 160° to 180°, regardless of whether you are moving or not, this usually is caused by a stuck open thermostat, or a thermostat that was replaced incorrectly.

What should the coolant temperature of an engine be?

It depends on the ambient air temperature and whether or not the AC is being used. Once the thermostat opens the engine coolant temperature can run from 210-230 degrees.

What causes a car temperature gauge to stay on low?

What could cause the temperature gauge to stay on low? The most common causes of why the temperature gauge stays on cold are faulty coolant temp sensor, faulty temperature gauge, broken wires, bad thermostat , and air pockets in the cooling system.

What causes an engine temperature sensor to go off?

1. Faulty Engine Coolant Temperature Sensor. The most common problem when it comes to a faulty engine temperature readings is the coolant temperature sensor itself which is sending the information to the cluster.

How can I tell if my Chevy Venture has a cold engine?

One check you can do without unbolting anything, (ONLY DO THIS WITH A COLD ENGINE) is to remove the radiator cap, make sure the radiator is completely full, start your COLD engine and see if the water in the radiator begins to move immediately.

Is there a problem with my GM venture?

It is a common problem for 1997 to 2002 GM products that have the 3.4L engine. It affects Chevrolet Venture and Pontiac Montana vans also. In the winter, the van would take forever to heat up and when it did there was little heat coming out of the heater. When it gets to -20 below, the heater would put out luke warm air.

However, most temperature gauges are integrated with the instrument cluster on modern cars. In some cases, you can replace the temperature gauge or repair any bad solderings if you find any.

Why is my engine temperature reading so low?

The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself, sending the information to the cluster. Some cars have two temperature sensors, while other car models have one.

What should coolant temp be when engine is hot?

With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.

What are the symptoms of a bad coolant temperature sensor?

Hence, it is advised to have your car inspected right away to avoid any serious problems. Here is a more detailed list of the common symptoms of a bad coolant temperature sensor. One of the first symptoms you will notice is that the check engine light will activate.
