Back flushing the radiator

[bluesman31]

You need to protect the radiator because it has the smallest orifices in the entire cooling system and acts just like a filter. In order to protect the radiator from clogging you have to filter the fluid before it enters the radiator top and clogs the tubes. The design of the gano is like a lobster trap that doesn't allow the grit to fall backwards out of the trap. I put the nylon hose on the side next to the radiator at the final stage of the filter as the fine mesh traps all the small stuff and then is trapped by the funnel shaped gano mesh from falling backwards. It works amazing. It is a pain to remove and a pain to clean because it doesn't come apart (takes about 15 minutes total), but works like a champ and I anticipate only having to use this setup for the first few hundred miles after the flush and clean. I have also added a temp gauge to watch in case I clog up the filter, but so far I am running at around 175-185 degrees measured at the head and top water inlet on an 80 degree day.

I agree that a coolant filter should be used. See #16 in my "Radiator Cleaning and Mess"
This is a cheap and easy filter to make.

I plan on posting pictures soon

What's one of these filters cost? They look real interesting.

An online search shows them to be about 60 bucks

I would love to see some more "home made" filter options. The GANO design, as it's lobster trap design keeps things from falling back into the engine, sounds like it would catch more stuff than the nylon home made filter.

The nylon drier sock ends in the upper tank the way I have it installed, so it will trap everything before it can plug the tubes, and it will hold any junk in the last few inches without it falling back.

I have seen cars over heat and boil because a Gano screen was fouled with fines that could not be seen by looking at it from inside the engine compartment. I think a nylon sock inside the radiator is a better bet because it is a filter with more surface area, hence less likely to plug up as fast as a small filter screen.

Any filter has to be checked periodically or it may clog and cause an overheat. If the filter wasn't there eventually the car would overheat anyway due to the radiator clogging. At least with a filter in place you don't have to remove and rod out or replace the radiator. Either way if you have a cooling system full of crap it is going to clog something. I choose the filter.

I was surprised how huge the mesh is on the Gano. If I didn't add the nylon sock I din;t think it would have trapped squat
