Reply to "Cooling System Tank Modification"

The -8AN fitting on the bottom of the header tank is used in conjunction with 1/2" ID hose, that's not all that small. I doubt if the outlet of your funnel is any larger.

Filling a Pantera is not something you can rush through, its about a 5 gallon system, and the radiator is at the opposite end of the car from the fill point. As you fill the system you'll begin to realize just how many places there are where air can be trapped.

After filling the next step is burping the air from the system, and that takes time too and it can be a headache. You start the motor so the coolant warms up and the thermostat opens, then you raise the rear end, raise the front end, back and forth until you think you've burped all the air from the radiator and the engine. With the vent system working that headache will be eliminated, just start the engine and let the system purge itself.
