What causes the temperature gauge to go down while you are driving?
The core, and thus the heating system, gets its thermal energy from the engine’s cooling system. Thermostat valves can fail in one of three ways: open, closed or stuck halfway. If the valve sticks in the closed position, coolant will constantly recycle through the engine without going to the radiator, causing the engine to overheat.
What does the gas gauge read when the tank is empty?
Most older sending units are a “0-30” or “0-60” ohm sending unit, meaning that when the tank is at empty, the resistance will read 0ohms, where at full, it will read 30, or 60ohms. To test this, simply put your mutl-meter to ohms (resistance) setting, and touch off one probe to the sending terminal, and the other probe to ground.
What should I do if my fuel gauge does not sweep?
If it does not, the issue is with the fuel gauge directly. However, if the fuel gauge needle does its sweep as it is supposed to, you need to perform further tests to properly diagnose the problem. The next step after performing the cluster test is to check the fuses.
What should the temperature of the automatic gearbox be?
TOPIC: Automatic gearbox temperature. Automatic gearbox temperature. As I understand it, the one thing that can kill a vehicle when towing is the automatic gearbox oil temperature. I want to find some sort of gauge that will give me a referance temperature, i.e.

How does a gas gauge work in a toilet?
The best way to explain the mechanics behind a gas gauge is to visualize a toilet float valve. Inside of your toilet’s tank there is a float arm. This float arm is how your toilet knows to shut off the water valve after you have flushed and the tank has refilled.
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.
When does your car run hot or cold?
If you are like most drivers, our guess would be almost never. Most drivers look at their temperature gauge so rarely that many vehicle manufacturers don’t even include temperature gauges any more but just lights that will come on if your car is either extremely cold or extremely hot.
Why does my car have a low coolant temperature?
Consistently low coolant temperatures could only mean one thing; fortunately, the required parts are fairly cheap and easy to install. An engine’s cooling system starts in its water jacket, which consists of a system of empty chambers placed around the cylinders and in the cylinder heads.
What should car temperature be at highway speeds?
Car temperature drops to a little less than 1/4 at highway speeds. Any reason to be concerned? Car is a Mk1 Golf. Driving around town the temperature behaves normally – it sits at the middle of the gauge, sometimes goes a little higher if I’m sitting in traffic but not much.
When does it get hot on the highway?
Thank you for your time around town it’s fine in 110 plus degree weather only on the highway around 70 ish mph for more than 15 miles is when it starts getting hot however when stuck in stop and go traffic it runs perfectly cool so I’m stumped. This says your dealing with a circulation issue.
What causes a car to overheat on the highway?
A plugged radiator will allow the engine to operate normally in town and on surface streets, but when driving at highway speeds with the engine running at a higher speed all the time, then the radiator cannot cycle the fluid fast enough and causes the engine to overheat.
Why does my car cool down at highway speeds?
Colder outside air means more cooling from the radiator. As your your other question, “could any serious damage have been done with the engine below operating temp at highway speeds…” The answer is probably not. You may have lost some fuel economy, but cooling an engine too much shouldn’t be too much of a problem.
