Cooling system.....revisited

[Jeff Balazs]

Hank;

I covered the ps question as best I could. Now if you talking about flushing the block in place then really about all you can do is pull the tap and the welsh plugs and hope for the best. I did all this last year and while I got a lot out ...obviously it is not all that effective. There is just too many places inside the block for it to settle into.

 

In my situation I think about the only way to really reduce the rust particles left in the system is going to be a fairly frequent drain down and flushing. I have a large plastic tray that they sell at Home Depot that is used for mixing concrete etc... I will just keep draining the system into it. I can filter and reuse the coolant mixture and flush with water until I get it as clean as I can. I don't see any other way at this point. I did not anticipate this much effort........but it isn't that big a deal. And it doesn't really cost anything.

 x 2 on that Jeff. My block was hot dipped, but leaving it sit too long probably caused most of my issues with flakey pieces in the system. I feel that regular flushing, combined with additives in the coolant, should eventually see a major decrease in the particles flowing around in my cooling system. The guys at the radiator shop have been getting less and less out of the cooling system each time I visit them for a full flush. Although, I do feel that their flushing method is a lot more thorough than what I could do here at home - given that they use high pressure mixed air and water to flush through the system. I know that one thing is for sure, I now have the temperature gauge in the truck sitting right about where I want it!

Can't recall 100% but I changed every bolt in my engine and I didn't need any special sizing or thread, I'm sure their a 3/8" by 2 1/4 or 1/2?? Something you can definitely get at the hardware store, only difference for me was I used coated grade 8's

 

that sounds about right.
