Amen. The recommended fluid change intervals are based on a lot of different variables which I won't go into here. For cars & trucks down here in Houston, TX take a manufacturers recommended interval time/miles and cut in half as a minimum. We have heavy duty conditions down here. Anti-freeze is just one component in our fluid inventory. I have a master mechanic friend of mine that has one of the best shops down here and he has many clients that bring their cars & big pickup trucks to him and they take the recommended schedule, cut if half, use BG Products and it's common that these vehicles get 250K - 400K miles on them, depending on the user. Fluid maintenance is everything in keeping things working right. Oh, and deep clean fuel injectors too, every 15K max.

As for me....everything flushed, renewed and changed out every 3-4yrs. max with BG products. If I put on a lot of miles it's 3yrs. It's pocket change to do this compared to what you'll pay to replace or repair any of these systems these days.

My 2 cents.

Don't know why Ford spec the post initial change interval less for both distance or time. Could be the water but I have yet to get my hands on the Ford published shop manual which would detail the procedure and such but I also use distilled for the final flush and dilution when I do a change with any vehicle.

I can not advise due to lack of info but I do know this.... GM has been experimenting with long life antifreezes, including at one time a completly sealed "Lifetime" Coolant fill that one was not supposed to change EVER. unless there was a problem (IE: busted radiator hose)

The person who suggested test strips may well have given the best advice.

Mine will be changed early next year..... No, did not blow a radiator or hose. blew an engine (Sad grin) so the coolant will be changed.
Home is where I park it!

On our Cummins engines, I have the cooling flushed about every five years. It is a little spendy, but a lot cheaper then having major engine work done.
