The car overheated to the point it set off the warning alarm. No fluid showing in the radiator reservoir. Fluid was below themostat. Antifreeze was added to radiator reservoir and restarted without letting the engine cool completely. Heard a metal pop sound. Then the metal clinking sound. Out mechanic thinks it's a broken valve spring. Running a little rough and you can hear the constant clinking of metal. The car has 179,000 miles on it. Is it worth repairing?

Hello,
when the car overheats, is there still water in the radiator?
If
there is water in the radiator and the car overheats, then it means
there might be some dirt or blockage in the radiator or condenser.
When
the car is on the motion, air passes through the front and assists the
fan to cool the engine. There are situation whereby air doesn't have
free flow because of blockage in the radiator and condenser. Dust and
debris can cause blockage. If this be the case, have your radiator
washed thoroughly and cleaned.
If there is no water in the radiator
when the car overheats, then there is a probably a leakage from the
water pump. Or maybe your fan isn't blowing properly. The fan might be
blowing weak air.
The above are what could cause your engine to over heat.
So
start the check from the radiator. Poor water into the radiator, wait
for some minutes, look under the car and observe if water is going to
leak. If there is a leak, it might be from the water pump or a leaking
hose.
If water from radiator has no leak, have your radiator washed
and clean the condenser has they might block air that is suppose to cool
the engine.
Also, make sure your fan is blowing properly or well enough to cool the engine.
Make sure you have the above checked thoroughly as they are the major causes of problems like this.
This
overheating problem could lead to a burnt gasket and this can dry the
engine oil which will eventually knock the engine. So have this problem
fixed to prevent further damage that will cost you more money.
Lastly, remove the hose that connects the radiator to the engine, water from the engine will come out. Pour water into the radiator, the water will flow through the hose down to the ground. Do this severally. Now connect the hose back to the engine, pour water into the radiator. Start the engine, the water in the radiator will reduce, add more water till radiator is full.
In summary, the major cause of over heating problem is from the radiator, fan, water pump, blockage in the hose, and dirt in in/on the condenser. These are area you need to concentrate on.
I forgot to mention that the acceleration meter or engine meter on the dash board shouldn't be more the 5. It should be below 5. If it is above 5, it can cause overheating. I hope you understand what I mean.....
Regards.
