Any suggestions on best practices to remove rust from cooling system? In process of installing new radiator but would like to clean out the block of any rust prior to the install. What products would you recommend to flush the system?
This was a few months after flushing and cleaning. I even took it to an oil change place for a "power flush". Took forever until the fluid ran clear.mORE LIKELY its old anti freeze over time it turns to a rusty looking muddy substance.

The rust comes right back.
I'm going to try the citric and maybe the evapo-rust. I've used that stuff before for other rust removal and it works pretty good.

Anything magical about having the ground at the back of the head? I have a ground strap from the engine block to the frame at the front. Nothing really going from the head to the firewall.If that is after a flush.
I would make sure your engine ground is good. It is located at the back of the passenger side head and connects to the firewall. It needs to have good metal to metal contact. So you may need to remove a little bit of paint.
I use a little dielectric grease between the ground wire, head, and firewall, it seems to keep rust away. I also do not use the stock cable. I make a cable out of black battery cable.
JMO.
That is where Ford thought it should be on almost every vehicle they made. The braided ground strap/wire they used usually rotted away though.Anything magical about having the ground at the back of the head?

A ground is a ground. Don't matter where it is. Ford chose the back of the head. The block to frame would work just as well.Anything magical about having the ground at the back of the head?
