Is flushing the coolant so hard that you need a flush fill connector?

I think the best theory I’ve heard behind those is that they’re best for letting off trapped air bubbles. If that’s the case it should be the highest point in the system, which guessing from your username is a 2F (although some things look different in the photo). Maybe a PO was trying to flush one of the heater cores? There are better and easier ways to do that though…
 
it's a 3FE, and that's an excellent theory.. getting the air out of the system. It does look like a garden hose connector fitting, so perhaps there's a garden hose involved as well.

either way, it's going bye bye and I'm putting in a rear heater bypass as some of the lines going to the back are leaking. It's daughter's project car so her friends can be semi-cold in the back.

Installed the bypass hose from @cruisermatt but need to buy some plugs now for the lines going back and one of the exits in the rear heater piping on the side of the engine.

Oh shoot, that should have been included in your kit. My bad. Shipping one out now.
 
I have nice rear hardlines if you want to keep the rear heater

Oooo... nice, which ones do you have? the leaky ones were the very back ones. I feel like I need to get the engine started first before I spend too much money on this thing. I'll hit you up when it's running.

No it's not. Those flush kits were a thing back in the day and a lot of rigs wound up with them. If you sell something, someone will buy it after all.

Not at all needed. I have never encountered a Cruiser that retained air bubbles anywhere in the system. To be honest I can not really see that happening. But *if* you did have that, or you are just really anal about fluid changes and you are not willing to just check levels a couple of times in the next day or three after a fluid change, then that fitting might serve some purpose for you.

Mark...
 
I got them all

Not in the least.

I hate those things. My old man had put one in my 62 before I got it and I replaced the hose at the first opportunity.
 
we used to use those back in the 70's. Besides that cut in fitting to connect a garden hose, there was an outflow nozzle that snapped into the radiator cap fitting. I remember parking my car over the storm drain and flushing everything down the drain. This was in California and today this type of behavior is not tolerated!

Edit: I guess Prestone still makes these kits! https://www.amazon.com/Prestone-AF-...&hvlocphy=&hvtargid=pla-4583451663267410&th=1

You might hurt the smelt!
 
I still say flushing the coolant through the engine drain cock is best, gets all the particles out from the bottom of the engine.
