No No No No No .... oldman. I never make anyone spend money unless it's their time to buy the next round of drinks. AND it's your turn !!!!!

You're old enough to remember .. In the old days, Chevy lever actuated fuel pumps and Fords water pumps went out about every time you need to do taxes. Ford got better with cleaning process over the decades. But as long as everyone does sand casting for the block, it will always have sand hung up in the inner walls that can, in time, break out and travel in the coolant. Not much, not like sand in the ocean waves on the beach. But one or more grains over time. This will break down and be finer for sanding surfaces. Bearing faces for one. I've changed out my coolant a few times on this truck, and many more on my prior trucks, but the filters have indicated over time that I am happy using them. If I have the time when I pulll the old ones off, I will cut the can open and see what's there. The last filter had a slight amount of gritty debris in 4 areas. I remember this because my wife 'had to see' what I was doing and had to know why.

But like I mentioned above, this does two things I like. It filters the coolant for clean fluids AND I (recommend) putting the coolant outlet from the block between the #5 and #6 cylinder on the head. This allows more coolant flow which helps in cooling that area more. Plus the filters are cheap.

You don't have to do anything. I just wanted you to know what I found over the years .. and you go from there.


After all I learned this from and oldman,
.. and now I'm and oldman, and if someone reads this and it helps,
.. when they become and oldman, they can pass it on.
.. all this from the original old man who taught me ?
