If a truck gets hotter after you shut it of is it the thermostat I have a 4x4 Nissan pickup with a 4 cylinder engine.?

All vehicles get hotter under the hood after you shut off the engine. This phenomenon is called "soakback" and is just the engine dissipating heat without benefit of air flow. Some cars with electric fans keep the fan running for a while to fight soakback. If you have an electric fan and it doesn't run after you shut the engine down, the fan relay may be broken.

What temperature thermostat should be used on a 350 Chevy?
It's dependant on what you want. If you live in a hotter climate, select a lower temperature thermostat; that causes the thermostat to open sooner, keeping the engine a little cooler... hopefully. If you live in a climate that is either normally cooler or seasonably cooler, a hotter thermostat can help the heater work better. A hotter thermostat has been demonstrated to be SLIGHTLY (almost insignificantly) at helping the engine run more efficietly.
Whats the normal engine operating temperature for a 83 Monte Carlo with a 305 and auto trans?
190 It is dependent on what thermostat you have in your engine. The engine will normally run hotter than the temp the thermostat opens at.
1947 Mercury with a 460 engine It runs hot no obstruction to the radiator The temperature runs up 210 to 215 it has electric fan- radiator fan was designed for this engine.has not bowled over?
My question is, where is the engine coolant temperature sensor located, in a cylinder head or in the intake manifold close to the thermostat? If it is in a cylinder head it will give you a hotter reading than if it was in the intake manifold.
Can you leave your thermostat out on a ford tempo?
yes 2nd answer: Yes, BUT, your engine will run hotter. Reason, the thermostat helps to slow the flow of coolant and therefor give it a chance to actually cool in the rad. thus letting the engine run cooler.
Your 1998 seems to run hotter in the winter now than in the summer just past--is that a computer control issue or do you have a problem that will show up later?
Engine temperature is controlled by the thermostat. An engine can often run hotter if the thermostat has started to fail or if the radiator is partially blocked. The computer is not involved in temperature control. Have the rad and cooling system flushed and change the thermostat at the same time. Have the heater core pressure tested and flushed out.
Why does your 1992 areostar overheat in -30 temp?
The coolant could have frozen in the radiator. If that happens the coolant in the engine will just get hotter. It could also be the thermostat.
How can you make your hot tub hotter?
hotter water turn up the heat using the thermostat on it
Why is the temperature keeps running hot in a 1998 Ford Contour?
It could be a stuck thermostat. If the thermostat is not opening fully it will not allow the coolant to move freely through the engine, making it run hotter than normal.
If you have a internal combustion engine and it was operating at peak horse power if you were to lean the engine out would cylinder temperatures increase or decrease?
Engines always will run hotter the leaner they are.
Can a 1985 Honda magna v-30 motorcycle run without a thermostat?
Any engine without the thermostat in place will run hotter. Reason is, the thermostat actually slows the flow of coolant so that it will have time to be cooled when it passes thru the rad. The stat also regulates the temp. of the engine and gives a more even temp.
How do you know if you need a thermostat in your car?
1. If the engine is running hotter than usual. 2. If the vehicle's temperature gauge is showing the low. 3. If upon inspection you see an open thermostat valve Symptoms like these likely indicate you need a new thermostat
Can you drive your 1995 lebaron with the thermostat removed?
You can but it is a bad idea. The thermostat helps the engine to reach it operating temperature and is necessary especially on computer controlled modern engines. It is a Myth that a cool engine is a happy engine. Actually, the hotter an engine is, the more efficient it is. It makes more power, lasts longer, and uses less fuel. Energy can either be used to turn the wheels or dumped as waste heat? Energy will tend to "follow the path of least resistance." If there is a large temperature differential between the combustion gases and the cylinder walls and head, the thermal energy in the gases will flow readily into the cool engine parts. If you reduce that temperature differential by making the engine parts hotter, less energy will flow. A hot cup of coffee in a refrigerator will cool down quickly and will cool to the temperature of the 'fridge -- a big temperature drop. On the kitchen counter, it will cool more slowly and will fall less (only to room temp). In a 200 degree oven, it won't cool at all. Same thing in your engine -- make the cylinder walls hotter and the thermal energy won't flow into them as readily. But that energy still has to go somewhere. Some will stay in the combustion gases and go out the tailpipe, but some will go into turning the wheels. So by trying to keep the engine temp low, you're throwing away perfectly good energy (and money)! A thermostat determines only the MINIMUM operating temperature, not the maximum temp. Under normal conditions, a cooling system in good repair can shed heat faster than the engine can produce it, so you need something to limit the capacity of the cooling system to dump heat. That's the thermostat's job. So you see, a thermostat cannot prevent overheating. It only prevents overcooling. A thermostat can only be the cause of overheating if it is defective and doesn't open as it should. The fix then, if your engine is truly overheating, is obviously not to put in a cooler thermostat or no thermostat, but to fix the fault in the cooling system. A cooler thermostat or no thermostat, is just a band-aid that at best can only temporarily mask the problem. Put the correct thermostat in your engine and if it is overheating, find and fix the problem. The fix is not to remove the thermostat.
