What does it mean when the left side of your radiator was smoking and it damaged the radiator cap when you took it off there was a lot of coolant in the radiator?

Your water pump might be broken or your thermostat might need to be replaced. You obviously don't have a leak so somehow the fluid isn't moving through the engine. If the thermostat is broken it will not let fluid into the engine and then the engine will overheat and the radiator will release smoke.

Why isn't the Radiator not getting hot?

Do 8 cylinder diesel trucks need a thermostat?

If, by "thermostat" you mean the radiator flow valve that controls engine coolant temperature, yes. All liquid cooled engines need such a thermostat.

How do you unplug radiator plug?

If you mean a freeze plug, that is usually in the engine block, not in the radiator. Maybe you mean a clogged radiator. If that is the case. First you would flush it out with water. You can remove the hose from the bottom. Then reattach the hose and add water and a chemical radiator flush product that you can buy from the auto supply store. Drive for about an hour of more. Then flush out the radiator again. Refill the radiator with water and see if your engine runs cool enough. If all that does still does not work go to a radiator shop and have them rod it out. If they can't do that, you may have to put in a new radiator. Good luck. One more thing. You may also want to check the thermostat.

What does it mean when radiator cold and engine run hot?

It means that the coolant is not circulating. Either from a lack of coolant, a stuck thermostat, a failed water pump, etc. **The water path from the radiator to the engine is blocked somehow. First look at your thermostat. This devise will regulate your water intake into the engine, if it is weak or gone bad, it will not work properly to regulate your cooling system. Check your hoses too, they can collaps and cause no water to flow. Then there is your water pump to check.

Where is the thermostat in a 1988 Chevy cheyenne?

If you mean cooling system thermostat, it is at the end of the lower radiator hose at the engine side. You will have to remove the hose at the engine end to see it.

What does it mean when temperature gage moves but not running hot?

Most likely the thermostat spring is weak, or the thermostat is sticking, causing the thermostat to open too early and stay open too long. This will cause water to circulate to the radiator, causing the temperature of the cooling water to fall below the target temperature, and so the temp guage falls. then eventually the thermostat closes some, and the temp starts to rise again (and so on)

What does rust coloured water in the radiator mean?

There is rust present.

What does it mean if the radiator cooliat in a car is not moving when the car is on?

If the engine is not overheating and the temp gauge reads normal, the thermostat is doing its job. If the engine is overheating, the thermostat may be stuck and in need of replacement.

What ff14 means is that there is a fault with the coolant temperature sensor. This could mean a blockage in the system (radiator, thermostat, water pump, etc), the temperature switch, or a loose connection.
