How would you add a coolant additive like "water wetter" to your system? I mean its a closed loop system right? So, would it be ok if you added the additive to your resevoir? or Should it be added during the refill after a flush? I got a 2005 K1500 w/ 190K. Yea shes old but she still runs awesome. BUT she gets a little hot on those long drives. So, I Just had a cooling flush and new thermo installed but can't get it lower than 200-210. Brand new it stayed at 195 or less. I know 200 is ok since 195-197 is the norm. Any thoughts? Thanks ahead this forum has been a great help!

You would have to remove the same amount of coolant from your reservoir. Go to auto supply and buy a suction gun to remove the fluid and then add back the amont of additive. CAUTION-Cooling system under pressure when HOT.
Very few people wash the outside of their radiator (the cooling fins), and they should. Dust, bugs, u-name it, and also bent fins, inhibit the cooling. Don't use a pressure washer because it can cause damage. Instead, use a garden hose and try to spray from inside the engine compartment to the outside, in the opposite direction that the debris entered.

What I would do after making sure that the motor has been thoroughly flushed, is as follows (one step after the other, only if the problem continues):
a. Clean the radiator passages as noted by another poster above.
b. Have a technician (or yourself if you know how), check the radiator cap to make sure that it's holding pressure. Also, to make sure that the pump is working properly. A pump not working properly can result on overheating conditions.
c. If the right thermostat was installed, then I would double-check the antifreeze/water ratio instead of adding chemicals to the antifreeze. In fact, I would completely drain the radiator and motor and start from the beginning with a new mixture of antifreeze/distilled water. Sometimes having too much antifreeze or too little water can cause a motor to run warmer than usual. If you have used pre-mixed antifreeze from the store, this one usually is mixed at an antifreeze/water ratio of 50/50. In this case, try adding enough distilled water to make the ratio something like 40 antifreeze/60 water and see what happens. Just stay close to the proper mix ratio for cold, temperate, or whatever region you live at.
d. If everything fails, then pay attention to the wind when you drive. Is it windy outside, and are you driving against the wind direction? If you are driving against the wind, driving uphill, or just towing, the results are the same: higher engine temperature.
