Reply to "Vacuum Fill Cooling System"

OaksterMember

I just did this on my 1972. I had pulled the engine and trans to address numerous leaks, upgrade the water pump and thermostat, and really clean up the engine compartment.

I used the Astro 78585 bleeding kit that I purchased off of Amazon. You need an air compressor to create the vacuum but it worked great. Car now runs nice and cool.

I have a LS swapped 1967 Camaro that will be right behind it to be vacuum filled.

Make sure you have a 5 gallon bucket full of coolant that start and that you keep the hose submerged in coolant so you don't suck air into the cooling system.

Just wish I knew about this tool sooner.
