Internal combustion engines run on heat, the fuel and air mixture is ignited to produce thermal energy, which pushes the pistons, spins the crankshaft and drives the vehicle. The hotter the engine runs, the more efficient it becomes, but there is a limits to that, eventually the engine will overheat and damage will be rendered. Normal operation temperature range for most engines is 195 to 220F, at these temperatures the thermostat should be open all the way to fully utilize the efficiency of the radiator. Keeping the engine at constant temperature is also important for fuel economy and proper performance of your vehicle. Every time you engine overheats, there is a chance it will undergo a significant amount of damage, which can result in very serious consequences, and eventually you can kiss you engine goodbye. The most common result of overheating is detonation, you will experience hammer-like blows that will damage engine components. Some of the common damage engine parts may be, rings, pistons, rod bearing, head gasket, and valvetrain components.

There are many things that can go wrong in the engine bay, that will result in the decrease of the radiator's ability to absorb, transport and dissipate heat. Anything that will prevent the mixture of water and ethylene glycol, or antifreeze, from performing it's normal cooling cycle; where it passes through the engine block and gets heated, and then through the radiator where it loses the heat through the atmosphere, and eventually goes back to the engine block to cool it. Water pump, thermostat, or loss of coolant are the more common reasons that cause the constant circulation of coolant to be disrupted, after which temperatures begin to rise, and the inevitable happens. Insufficient performance of the OEM radiator, under different circumstances, however, is probably the most common cause of overheating for performance vehicles that are put through strenuous heat cycles and endurance situations.

Factory radiators are designed for performance in vehicles with OEM power output and daily-driven conditions. Once you start upgrading your vehicle with aftermarket performance parts, and pushing the limits of your vehicle with strenuous activities on and off the track, the heat generated by you engine increases, therefore making the OEM radiator unable to perform the sufficient enough task as a "heat exchanger" to adequately cool your engine. The plastic end tanks attached to aluminum cores in OEM radiators are vulnerable to steam erosion and corrosion. When internal corrosion takes place, over time the radiators tubes get fully plugged from rust and sludge, deteriorating on the coolants normal cycle, resulting in overheating, yet again. Unable to perform a sufficient enough task of pulling atmospheric air through the radiator at slow speeds, factory fans that come with the OEM radiators can also be the reason for overheating. Their task just, like the thermostat, is very important: to help maintain a constant engine temperature for optimal performance of the car.

Upgrading you current OEM radiator and fan to an aftermarket branded, lightweight, high-quality aluminum radiator and fan can help you solve most heating issues in your performance vehicle, and also reduce a significant amount of weight in the engine bay. Most aftermarket radiators are designed with internal tubes that are 1 to 2 inches in diameter, compared to factory ones, which use.5 inch tubes. Large in sized, and flat in dimension, internal cooling tubes increase capacity and surface area, this results in effective heat dissipation and more efficient cooling. Fins are also an important factor in aftermarket radiators, perfectly optimized fin-density is essential to obtain maximum air travel through the radiator to aid efficient cooling. Mishimoto radiators are top of the line performance radiators that have the right balance of fins and tubes to make it an ideal cooling system for your vehicle. Mishimoto radiators are made from 100% brazed aluminum, they are very slim and therefore will easily fit in place of your OEM radiator without any modifications and are designed to increase cooling efficiency, boost engine function, and protect your performance vehicle from overheating. It is highly recommended to use Mishimoto aluminum fan shroud kit for optimal cooling performance, it will deliver that so important amount of air to the radiator and suck the excess heat from you engine.

The last factor that can increase your aftermarket radiator efficiency is diversion panel. Diversion panels are installed to cover the open area between your car bumper and the radiator, above the radiator and sometimes below. Their full purpose is utilized at freeway speed, by diverting the incoming air to pass through the radiator, instead of gathering in front of the radiator and escape to the space above and below. When the car is at lower speeds this task is performed by the fan behind the radiator. By directing the air at high speed thought the radiator, you achieve maximum radiator performance and can lower your temperatures by those important few degrees.

What makes Engine work?

Engines are supposed to be the most important part of a car. It is not possible that you can run your vehicle without a proper engine installed. There it is supposed to be the most vital part of any vehicle. There are certain parts in an engine which are highlighted here. A proper blend of all these parts will make the engines perfect.

• The spark plugs are one of the important parts of engines. They help in the initiating the engine and thus a car. It is very important they spark plugs work properly. Make sure that these are smoother enough. The spark plugs are required to be replaced in proper time gaps so that it works properly.
• You have cylindrical shaped components here which are named as pistons. They move in an up and down trend. They basically work for the purpose of compressing the air along with the mixture of the fuel that is filled in the cylinder.
• Another part of the engine is piston rings. As name suggest these are placed in the region of pistons and they stop the air and fuel to come out of the cylinder at the time of combustion.
• Valves are another part of engine which is generally of two kinds. One is the intake valve and another exhaust valve. As the name suggest intake valve allows the fuel to come in during combustion and the exhaust valve opens to let all the air out after combustion.
• Apart from this you also have crankshaft in an engine which operates alike to pistons but with a difference that they move in circular motion so that it can help the pistons working which are connected to the crankshaft.
• You have a flywheel that is located behind the engines part crankshaft. It fluctuates the engines during the ignition time. Thus it allows the car to start properly.
• Another part is the connecting rod which is made up of metal. The work of the connecting rod is to connect the crankshaft along with the piston. It helps in proper motion of the crankshaft and the piston.

These are certain parts of an engine which are important to be in sync so that it works properly thus allowing the car to initiate properly. So now that you know about these parts, you will be able to analyze it is a very proper manner.

460 motor rebuild. crankshaft wont spin at piston #7?

I'm trying to get my engine to run. I bought the truck like this. It is a 460 ford motor. I have 2 motors, one for parts and the other is the one I'm keeping. I took them both apart. The one I'm keeping had the valve brake and broke the piston. I replaced the piston with the parts motor onto mine with the connecting rod attached. This is the number 6 piston from both motors. I had loosened up all the connecting rods before but after I tightened them, the crankshaft wont spin when I turn it with a wrench in front. I thought that it was tweaked so I replaced that crankshaft with the crankshaft from the parts motor. The same thing happend. Now, I have all the connecting rods tight to torque specs (45 pounds) except for the #7 piston. When I tighten #7 to about 30 pounds, the crankshaft gets real hard to turn and at 45 pounds it wont spin at all. After this, I replaced the connecting rod rings with better ones from the other motor, and lubed it, like all others,, and still the same. Help.

Sounds like you need the bearings replaced. Check the bearing in the #7 connecting rod for proper measurement and damage. Tough without seeing it but it sounds like the crankshaft is getting clamped by the con rod and bearing.
