It opens wide open sooner to try and keep the temp cooler.
If you change to a lower one I believe you need to have the tune adjusted or you will get a code for it not functioning properly.
As far as the cap, make sure its sealing and its not damaged. Make sure the gasket (or in this case I believe they use an O-ring to make a seal) is in good shape and not damaged.

Dang I appreciate it,sucks I don't live near anyone on here. But anyways I went with the Napa Heavy duty fan clutch and a Napa thermostat but I'm still nervous about the fan clutch. After I bought it I called about the warranty and then the guy said the heavy duty is for the towing package and I don't know if my truck is the towing package( no hitch but has the towing button on the shifter) but I keep hearing their loud and power robbing and they don't cool as well

Ok, in the name of getting some things straight and not really helping your situation, I see misinformation happening on how a fan clutch works.
Spinning after the engine shuts off while hot is BAD. If the clutch cannot turn by hand when the engine is off, you might (very rarely) have a seized clutch, or the clutch could be very hot (perfectly normal for the clutch, but means poor cooling by radiator), but either way you are getting air pulled through the radiator. If the fan does any freewheeling while the cooling system is hot, you have a defective fan clutch. It shouldn't spin more than a couple of seconds after shutdown and have a very stiff/gooey feeling when you turn it by hand.
As far as this:
Whoever is telling you this information is incorrect. Logical fallacy. "Loud" and "Power Robbing" do not go along with "Not Cooling Well". Both Loud and Power Robbing means it's spinning the hell out of the fan and moving a crap ton of air. A crap ton of air moving means a crap ton of thermal transfer happening at the radiator. Generally, a crap ton of cooling at the radiator means a cooler running engine.
The fan clutch works by detecting heat coming from the water pump shaft, which is heated by moving hot coolant around. When it gets hot enough the fan clutch (which uses a viscous coupling) begins to engage from partial to full output depending on how hot the clutch gets. Full output means the water pump is getting very hot. Partial output (gooey feeling and not a lot of noise) means the system is running at an optimal temperature. Freewheeling means the system is cold and the fan is not required.
Now as to your last question, there is no difference between the two clutches except that the Heavy Duty clutch will engage slightly sooner than the regular clutch, to keep airflow up at lower speeds while towing. Since you have a truck I recommend you go with the HD clutch and just live with the noise...or swap to e-Fans and live with the noise. Noise = airflow = cooling.
he guy who does most of the work on my truck said the clutch was bad, whenever I cut the engine off the clutch cut the fan off immediately when he said it should have kept spinning
