New Fan and Cowl, Properly Spaced. Replaced the Thermostat, plenty of fluid and no leaks. I put in a new water pump about 6 months ago.
Overheats (boiling) after short 10 minute drives. Takes longer to overheat while idling. Any Idea what it could be or ways to find out what it could be?

It sounds like you might have an obstruction in the radiator. Each of the 'rows' of a radiator carries a small amount of the coolant and affords lots of surface area to dissipate the heat. If the radiator has ever been 'repaired' it is not uncommon to solder some of the passages closed in order to wall off leaky areas. This reduces the radiator's capacity. Also, it is very common for an older radiator to become plugged up from calcium deposits and metal corrosion. This has the same effect as soldering parts of the radiator closed to avoid leaky areas. I would take it to a radiator shop and have them test it. They can 'boil' out any obstructions and find any inoperable areas of the radiator. This is usually a very reasonable repair, even if they have to totally rebuild the radiator. The radiator is very likely NOT completely obstructed which would mean you are circulating coolant, just not getting enough of a cooling effect from the impaired radiator.
Once you are sure the radiator is doing its job, then you can determine whether there is any other problem in the system such as a poorly performing pump (not uncommon in cheaper, aftermarket pumps) or thermostat.

Well the next thing is see if the radiator is plugged the easy hill billy way disconnect your lower radiator hose and use a garden hose to let the water go through it it should be coming right out if that works the take of the upper hose and stick the hose in there see if it still flows good if yes then. Move to your heater core Does the car blow good heat? If no then its problem plugged to trouble shoot pull both lines off of the water pump and try to put water threw it or blow threw it I blow that's me. If you think that's plugged but your not really sure then you can take one of the pieces of heater hose and loop it on the water pump so it bypasses the heater core then . If none of this works my friend well Then trouble shoot for a bad head gasket or cracked head. It will be blowing alot of white smoke and will overheat really fast as you described good luck. hope all is well.

in the previous assuming that's a blown head gasket, what does your coolant appear as if, sparkling green or milky? additionally, as a manner to get rid of any doubts of your cooling fan/grasp, stress for the quarter-hour at fifty 5 mph, and if it nonetheless overheats it has no longer something to do with the two of those. As stated past, it does sound as in case you're able to desire to have a thermostate project. to make certain, eliminate yours and place in a warm water tub it fairly is basically above the specified beginning temperature and if it does not open, walaa. an selection, replace your thermostat besides because of the fact they do no longer seem to be that expensie. additionally, does your overflow refill interior the 1st 5 minutes of idling? If there is intense/untimely overflow tank filling, you ought to probable to get your radiator cap stress examined (unfastened at maximum interior sight vehicle factors shops). the only different project i can think of of is which you will have air bubbles on your cooling sytem and out of your description this sounds very achieveable. i don't be conscious of myself, yet i might suspect that there could be an extremely particular technique for draining and filling your cooling device and you're able to desire to have left an significant step out and thanks to which you're seeing some air on your coolant.

i own a repair shop,and you might need to take the radiator off and have it flushed out real good,it sounds like its not letting the coolant circulate all the the way through it real good,that why the top is hot,and the bottom is cool on it,all of it should be warm,that's probably the cause of your over heating right there good luck with it.

Assuming you put the thermostat in right side up, your radiator may be completely plugged.
ADDED:
Coolant should be flowing quite fast when the thermostat opens.
I'm sticking with plugged radiator........

If you're sure that you don't have a failed new part (I've seen new parts that were bad) then I'm going to have to agree with the radiator being the most likely cause.

There is a good probability that the radiator is at fault. It must need to be reamed out.

You could also have a "vapor lock". This is where there is large airbubble trapped in your cooling system. It would need to be suctioned out.
