Diesel engines are heat-generating sources. They are cooled by circulating a water-based coolant through a water jacket, which is part of the engine. The coolant is circulated through pipes to the radiator to remove the heat added to the coolant by the engine and then back to the engine. Where is the thermostat on a diesel engine? The thermostat is a temperature-controlled valve placed at the engine coolant outlet on most engines.
An encapsulated wax-based plastic pellet heat sensor is located on the engine side of the thermostatic valve. As the engine warms, heat swells the heat sensor. What do modern electronic thermostats use to sense temperature? Electronic thermostats utilize an electronic heat-sensing element and circuitry to sense temperature changes and turn on heating or cooling equipment. How much is a radiator for a Nissan Altima? This sounds normal. As long as the temperature gauge does not go past the "normal" range then the quicker it gets there, the better that is.
We want the engine running at what is called, operating temperature. This is where it is most efficient so again, as long as it is not going to the hot range, this is okay. Please let us know if you have more questions. Thanks Was this answer. When I start my car in the morning to let it warm up, it never warms up while sitting idle.
No matter how long I let it warm up it never does until i've been driving for about 15 minutes. Could this be a problem with the thermostat? Yes, most likely the thermostat is stuck open or missing. Does the gauge show snything after 5 minutes if engine running? When it's sittin still the gauge does not move, but after driving for about 10 minutes it starts to move Was this answer.
This might be electrical instead of temperature problem. It could be the gague that is causing the problem. My switch on the panel is stuck it does not go from cool to heat.
I had noticed it was sticking about half way but then I had to force it to the warm side and then he wouldnt go back to the cool side. But when I turn the fan on it blows out cool air even though the thermostat is on the warm side. Not sure if because it is stuck which is causing me not to have heat or if the heating element is bad.
Look to make sure this black sheathed steel cable is attached to via a metal clamp and most importantly snapped onto the plastic "gear" to move forward back the round gear.
Reattach or perform fix below. The "knob" in the control panel attaches to a small steel cable in the back and the plastic clip in the back is most likely broken. Notorious design flaw.

Where is thermostat located? In most cars the thermostat is placed under a housing near the water pump on the cylinder head ; the housing is connected directly to the top radiator hose.
In a few cars the thermostat is housed near the bottom hose. Test the thermostat quickly by starting the engine from cold. Hibernon Coith Teacher. How much is a radiator for a Nissan Altima?
