How hot ? not to be able to touch it ? Resistance (high resistance) causes heat. Lose connections, corrosions, wiring that has been open for a while. which caused green crusty (corrosion)Fuse / relay box has corrosion inside . Looking at wiring diagrams an using a volt ohmmeter to test electrical circuits is the way to a fix. You don't know that ,take it to a qualified repair shop.

There could be several reasons why your Corsa Lite is refusing to start when the weather is hot. Here are some possible causes:

1. Weak battery: High temperatures can cause the battery to lose its charge quickly, and if the battery is already weak, it may not be able to provide enough power to start the engine.
2. Faulty starter motor: If the starter motor is faulty, it may struggle to turn the engine over, especially when the engine is hot.
3. Clogged fuel filter: A clogged fuel filter can prevent fuel from reaching the engine, which can cause starting problems.
4. Vapor lock: In hot weather, the fuel in the fuel lines can vaporize, causing a vapor lock, which can prevent fuel from reaching the engine.
5. Ignition problems: If the ignition system is not functioning properly, the engine may not start, especially in hot weather.

To determine the exact cause of the problem, you may want to take your car to a qualified mechanic who can run a diagnostic test and identify the issue. They can then make the necessary repairs to get your car up and running again.

It is normal for an electric heater to feel warm to the touch when it is in use, but if it is suddenly hot to the touch, it may be a sign of a problem. Here are a few possible reasons why your Comfort Zone CZ650B 750/1,500-Watt heater may be hot to the touch:

1. Overheating: If the heater has a built-in thermostat and it is suddenly hot to the touch, it may be overheating. This could be caused by a malfunctioning thermostat, a clogged air filter, or a problem with the heating element.
2. Blockage: If there is a blockage in the heater, such as a piece of debris or a build-up of dust, it can cause the heater to overheat and become hot to the touch.
3. Electrical issue: If there is a problem with the electrical system of the heater, it can cause the heater to overheat and become hot to the touch. This could be due to a malfunctioning switch, a faulty power cord, or a problem with the wiring.

If your Comfort Zone CZ650B heater is hot to the touch, it is recommended to unplug it and stop using it until you can determine the cause of the problem. If you are unable to determine the cause of the problem or fix it yourself, it is recommended to have the heater inspected by a qualified technician. They will be able to diagnose the problem and recommend the appropriate repairs.

There could be a few different issues that could cause the temperature gauge on your 2008 Ford Focus to read hot when the engine is not actually overheating. Here are a few things to consider:

Failed thermostat: The thermostat is responsible for regulating the flow of coolant through the engine. If the thermostat is stuck in the closed position, it could cause the temperature gauge to read hot even though the engine is not overheating.

Failed temperature sensor: The temperature sensor sends a signal to the temperature gauge to indicate the engine's temperature. If the temperature sensor is faulty, it could cause the temperature gauge to read hot even though the engine is not overheating.

Wiring issue: If there is a problem with the wiring that connects the temperature sensor to the temperature gauge, it could cause the gauge to read hot even though the engine is not overheating.

To determine the cause of the issue, it may be necessary to perform some diagnostic tests and possibly replace some components. A mechanic or a professional auto repair shop will be able to diagnose the problem and recommend the appropriate repairs. It's also a good idea to keep an eye on the engine temperature and take note of any other symptoms or issues you may be experiencing. This information can help the mechanic diagnose the problem more accurately

missing a little and running hot are indicators that you could have a head gasket problem. have it tested for a bad head gasket. the missing could be caused by coolant leaking into the cylinder causing a misfire, because of a bad head gasket. running hot is another indication of head gasket. if the rad cooling fan working properly. I think these have what is called a clutch fan which means, when engine is cold the fan turns slower than it does when its warm. if its turning slow when warmed up like when its cold it could be the fan causing the hot running.

Hot starting problems are usually fuel related. When a hot engine is shut off, the temperature of the engine and everything on it continues to rise for awhile as the engine undergoes a period of "heat soak." This can cause fuel to boil inside the carburetor bowl, fuel lines and fuel filter. When you attempt to restart the engine, "vapor lock" obstructs the flow of fuel and the engine doesn't want to start.
This is much less of a problem on fuel injected engines because the fuel is usually under much higher pressure inside the injectors and fuel line. Even so, a fuel line routed near an exhaust manifold or a fuel rail that's exposed to a lot of heat may still suffer the same kind of problems.
Heat soak problems such as these can sometimes be cured by wrapping insulation around affected fuel lines, and/or installing an insulating spacer or heat shield under the carburetor.
A Seasonal Problem Hard hard starting tends to be a seasonal problem, but may be worse in the early months of spring when refiners are switching fuel blends. Gasoline refiners produce fuel with a slightly lower volatility rating (called "Reed vapor pressure") during hot summer months because lower volatility fuel is less likely to boil and cause hot starting problems. During the winter, they switch to a higher volatility fuel because it makes cold starting easier. But if you still have "winter" grade fuel in your tank when warm spring weather arrives, you may experience some hot starting problems. The problem will go away, however, as soon as the refiners in your area switch to their summer grade fuel.
Other Causes Hot starting problems can also be caused by cooling problems that allow your engine to run too hot (the pistons swell up and may scuff the cylinder walls), or excessive resistance in the starter motor that causes the engine to crank slowly. A starter "amp draw" test can be used to check the condition of your starter. Also, many starters have small "heat shields" to protect them from heat radiating from nearby exhaust pipes or manifolds. If the shield is missing, the starter may get too hot and bind up.

1) Make sure factory-supplied insulation and cover are reinstalled over thermostats, or cooler room temperature causes thermostat to under-approximate tank temperature, and this causes overly hot water.

2) Replace both thermostats.
Sticking thermostat can seem to act normally when tested, but when left alone it sticks, causing runaway overheating.

I know there are not that many sites--very few--that cover the informational guidance on the maintenance and technical difficulties of evaporative coolers, and so I feel compelled to share with you this very good, but rare, handyman site that does:

http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Coolers.htm

As you'll see, the link above has a section dedicated to evaporative coolers.

As to your specific problem of your cooler's blowing hot air, yes, the humidity is listed as one of six (6) possible causes of this cooler problem. To find out whether the other five causes are applicable to your situation, here is the direct link to the diagnostic article on hot-blowing coolers:

http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Coolers_Cooler_Does_Not_Blow_Cool_Air.htm

You should be able to review this article, and, one by one, determine what causes listed therein are not affecting your cooler in order to ultimately end up with one remaining listed cause that is the likeliest cause of your cooler's failure to blow cool air into your house.

This should help.

Good luck!

You will have to be specific about what problem the pump is having. It seems to pump ok for everything else. Could the hot solenoid be shorting and sending electricity down the water to bother the pump? Solenoids are not real expensive, try a new one.

Check electric fan on radiator if bad will cause this problem
