When the temp rises and falls , it is almost always a head gasket.
Yes, the heat rises to the top of the engine.
The engine may cut out when the temperature rises because the engine could be overheating. It is best to have a mechanic inspect the car and make any necessary repairs.
no, it is powered by heat. heat rises.
This is because your vehicle's engine is almost at the highest operating temperature as you drove a long drive and you may have shut the engine down without letting it to cool for a minute or two. here what happens is your engine is hot and the heat is exchanged through the radiator to atmosphere when you stop the engine it does not do as it runs. the stored heat energy in the engine rises the temperature and boils coolant when you shut the engine off immediately after a long drive. this habit is especially not good for some of the engine parts such as turbocharger, oil seals and rubber gaskets. I guess this is your case as i guess all other parts of your engine works perfectly.
Check the motor mounts
Possibly as an engine aquires miles oil consumption rises. Depending on how and where you drive would determine this also. Hard driving and mountains will increase oil consumption as well as leaking gaskets which are also common in a high milage engine. At least you are keeping an eye on this as some don't.
When engine temperature rises, the brake sees vacuum and pulls the choke open.
Yes, when the a/c is used the engine works harder which rises the temp of the engine then turn the fans on to cool the radiator.
Efficiency would increase.
Automobile cooling fan can cool the automobile engine when the temperature of the automobile engine rises, ensure the normal operation of the engine and protect related parts, and reduce automobile failures. If the car cooling fan is not used, after the engine is started, the temperature of the engine rises during the driving of the car, which may easily cause the car to malfunction and even cause the car to spontaneously ignite.The above answer is provided by Suzhou Santian Precision Mould Manufacturing Co., Ltd.
do you have a/c switched on when this is happening a/c makes engine idle up and down as it cycles on and off
The pistons are running in the cylinders of the engine, so when the rpm of the engine rises, the pistons quickley build up speed. It is this rapid acceleration of the pistons that casue the car to shake.
