What should the coolant temperature be in a car cooling system?

What should the coolant temperature be in a car cooling system?

As a general rule, cooling systems are designed to operate with a coolant temperature of about 190 degrees F at the radiator inlet and have about a 10 degree F temperature drop through the radiator at rated power and rated coolant flow. This will result in a bottom tank temperature of 180 degrees F.

Can a radiator change the temperature of coolant?

That is, for a given heat load and coolant flow rate, the coolant temperature drop through the radiator will be constant, and nothing anyone can do to the design of the radiator can change that. Adding rows or finsor face area or whatever will not change the temperature drop through the radiator.

Where does the coolant go when the engine is running?

When an engine starts and is run up to rated load, the coolant begins to heat up. When there is no thermostat in the system, the coolant flows from the engine through the radiator and back to the engine.

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.

What should the temp be on my GMC Truck?

After getting it back from having leaking intake gasket replaced, the temp would go up to 260 before it went back to 170 and then would sit for a little bit, go back to 210, back to 170, back to 245 or so, then back to 170, but It never seemed to run hot. I changed the thermostat with a brand new 190* from NAPA and it seemed to cure a little of it.

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.

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.

Why is the temp on my radiator going up?

As the temp gauge rises, check to see if the radiator fan engages. If it doesn’t, there’a a problem in the fan circuit. This could be a bad fan motor, bad fan relay, bad coolant temp sensor for the fan, or a blown fuse for the fan circuit.
