back flushing the coolant from the block

[LaGrasta]

Is the plug on the exhaust side of the block meant to be a place of input for back flushing? Thus far, I only removed each hose and blasted water in from the garden hose until it ran clear.
I didn't use any radiator flush products as I didn't want to loosen scale and clog the radiator.

LaGastra, From the plug you refer to, I installed a "T" for my water temp sensor as well as for the 5/8"dia. heater hose that runs from my carb spacer to the heating core. I have a 200cid engine. In the 5/8" hose I installed the "Tee" for flushing the engine and radiator. That puts the "T" before the thermostat; so I believe that would cause the water to flow in the opposite direction (than it flows under normal driving conditions) for the purpose of flushing the system!???? Anybody else??? Good Luck, Jim

So maybe I can unscrew the plug, install an adapter for the garden hose, and flush away? Sounds liek essentially what you are doing. Anyone else?

To properly "back flush" your cooling system you remove the thermostat,and use a pressure flush tool that uses air pressure +water.
Disconnect the lower hose before doing the reverse flush.

Check with a marine supply house,or a truck stop for the type of inline coolant filter that you want.
Be prepared for sticker shock.

A drop in anode will help with chemical reactions in the radiator.

Hey superheat, there's an Aussie company called "TEFBA" who sell one that's pretty well regarded. With shipping, it would run close on $90 I'd guess.

Hi mustang6 that type is nice,but if you will notice it will let fairly large pieces through the filter screen.
The type that I was referring to is the type that WILL remove ANY debris in the cooling system,INCLUDING mold sand which is released from the cast iron for the life of the casting.
Whatever that casting may be,if it is exposed to water or other liquid.

The biggest hurdle with the Gano type (IMO) is that they're not so easy to empty out as the TEFBA. "Jag Lovers" did a bit of a write-up on a few filter types and while the Gano was OK, this got a bigger vote.

Website is a bit hick, but the product not bad.

Az might want to think about carrying these.
