What is a freeze plug?

freeze out plugs are metal plugs in the block and heads of your engine. they are are there if the coolant was mixed wrong with to much water and the vehicle freezes they will pop out allowing expansion of freezing liquid hopefully saving the engine Part 2: You will see these called freeze plugs, casting plugs, welsh plugs and probably other terms. The holes they plug are part of the cylinder block casting process to allow molten steel/iron/aluminum to rapidly flow into the block casting mold. The fact that they will pop out if the coolant in the engine freezes can be serendipitous but in most cases the plugs go bad due to galvanic action: the steel plugs installed at the factory are dissimilar to the engine block metal and will start to corrode (rust) and will start leaking after a while. This is why most antifreeze manufacturers claim they have anti-corrosion protection; it is also why 99% of replacement plugs are brass. Three points to remember: 1) before replacing plugs do your research and find out EXACTLY how many plugs your engine has and where they are. 2) if you have to replace one plug, replace them all. 3) if you are rebuilding an engine it is cheap insurance to replace the plugs.


What is the different between V6 and In-line 6 ingine?

An inline engine has all the cylinders in a straight line. A V engine has 3 on one side and 3 on the other with the cylinder block actually in a V shape. The V shape was originally used to save space because a V engine is a little shorter than an inline engine. In the old days it was believed that an inline engine would produce more torque and a V engine would produce better horsepower and higher RPM's because of better balance. In today's world with computerized manufacturing we are back to more about space than anything.


Why does headgasket blow?

I interpret your question to be: Why do head gaskets (on an engine) blow-out? There can be several problems: The engine head itself might have been tightened incorrectly (misstorqued). This can happen when the engine was first assembled or after a repair. When this happens the pressure on the gasket in not even and not tight enough in places, so the gas pressure of the engine finds the weak spot. The gasket might be defective. Most gaskets have multiple layers bonded together. If the bonding is not correct or a gasket layer was misscut, again, the gas pressure will find the weak spot. The engine head or cylinder block could be warped. This can happen when an engine severely overheats. The two components will not bed the gasket properly and the result can be a blown gasket. The gasket could have simply worn out. They do have a life expectancy and require replacement when the engine ages.


What is the difference between a big block engine and a small block engine?

The difference is in the design of the head. Also due to the head design, the physical size of the motor is larger even if CID (displacement) is identical. The best visual example I can think of is Ford 351 windsor which was a small block: http://www.mustangsteve.comW351_65.jpg and a Ford 351 Cleveland which was a big block: http://thunder-performance.com/images/Tony\'s%20351%20Cleveland%20(1).JPG Generally you can tell the difference by looking at the valve covers. if they are long, narrow and rectangular, it's a small block. If they are fat squat and irregular shaped, you're looking at a big block. There are other differences too, for example bore and stroke. A small block generally has a shorter stroke and is thought to rev higher, whereas a big block has a longer stroke with more torque. There are other disputed difference between a small and a big block. And for the most part, you can simply tell by the displacement. Generally, anything larger than 366 CID is a big block.

Does water remain in engine block when cars not running?

There is coolant in the engine block when the engine is not running. The engine block, heater, hoses and radiator remain full when engine is not running.


What is heavier an air cooled car engine or a water cooled car engine?

The water cooled engine will typically be heavier, because you have to add in the water pump, the radiator and the water/coolant. The engine block itself may be lighter as there are passages drilled out for the water/coolant to flow through.


What temperature does an engine block crack?

Marine engine blocks will crack when the water in its passages freezes and subsequently expands. If the passages are full of water inside an engine, the frozen water needs somewhere to go sotheoretically it makes room by cracking the block, hence making it bigger. If an engine was subjected to a constant 32 degrees over long enough time to freeze entirely that would be enough. However, the manufacturers install "freeze plugs" in key spots so they give before the block. This buys some time. A few cold nights wont crack a block, but winterize the engine with antifreeze before the long cold winter sets in.
