I found one of those long clear funnels, mine is like 24" long. I have seen them at all the major parts store chains, walmart, lots of places.
I cut the funnel on the bottom till it was just under the diameter of the opening (for flow) then I jam it in the radiator opening, it locks in and does stay still.
The problem with just putting fluid in is when it first heats up and starts expanding, more fluid is ejected from the radiator than should be... making a mess for one and shorting the cooling system of needed fluid.
Using the funnel... first fill the radiator then put the funnel in.
As the truck heats up you will see the fluid rising in the funnel. Then when the thermostat opens it will suck it in quickly. This is when you pour more fluid in the funnel, just till you can see it on the bottom just below the radiator opening.
This will happen 2 or 3 times because the first time it sucks it in the cold fluid it sucks in will close the thermostat!
You might see as much as 8" of fluid rising in the funnel before it sucks down.
When you put the fluid in it and it stays under the funnel with the temp gauge where it normally is... then it is OK to remove funnel and put the cap on. Since the funnel is translucent you can even see the coolant flowing just under it!
No mess, no fuss, no expensive vacuum filler devices... all is well.
Don't forget during this to turn your heater on even if it is summer. This allows the fluid to fill the heater core also.
