In the event that it over-heats and seizes, then yes.
If your cooling fliud is plain water, and the engine hasn't frozen, then lack of antifreeze should not affect things in the short term. It is obviously desirable to have antifreeze in cold weather so the the enginge doesn't freeze. As above, if there is no cooling fluid at all, the engine will over-heat and sieze up.
the most common cause would be a stuck closed thermostat.
cracked head or bad gasket
A bad head gasket is the most common cause of antifreeze mixing in the oil. The antifreeze will dilute the oil and it will eventually cause your engine to seize up.
it could do
If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown. If it is transmission fluid in your antifreeze, then the radiator is leaking from the transmission cooler ----- although usually that would cause antifreeze to be in your transmission fluid.
no Yes, it can cause the belt to squeak and slip.
Something has bound the shaft or crank on the engine to cause the key to pop. Could be if it backfired - that will cause the shear pin to break - or if you caught something underneath it with the blades that would cause it.
in some case it will. the composition of antifreeze is different by colour. in some engines the chemicals react with the engine parts (i.e. gaskets or seals) and cause the parts to fail. use the proper antifreeze for your engine.
Thermostats determine when antifreeze enters the main cooling system. If the thermostat isn't working correctly, the antifreeze could enter the engine to late, (or not at all) resulting in an over heating engine. Another problem of having antifreeze enter the engine late, is that if your engine is very hot, possibly a little warmer than common, when the antifreeze enters the engine, the cold fluid could cause the engine block to cool down quickly, causing a cracked engine block.
When antifreeze is poured into your oil, it weakens your oil cause it to break down prematurely and can cause your engine to fail by spinning an engine bearing and even smoke. This is also a sign of a blown head gasket.
Internal engine antifreeze leak what else could cause besides headgasket? there is no antifreeze in the oil it is clean
It could be that your head gasket is shot. It may cause your antifreeze to leak, and your engine will overheat.
