Cavitation???
I just sold my 86 F250 with the 6.9, and prior to that had an 84. One thing I was real careful about in those trucks was the maintaining the SCA level in the coolant to prevent cavitation. I just bought an 05 F250 with the 6.0 about 3 weeks ago (and have already put 3k miles on) and was curious if that is an issue with the new diesels. Also, this being my first new truck, does anyone have any other tips or info that might be of some use????
Thanks,
Sean
BTW- saw diesel the other day for $3.39 gal!!!!!! Why is gas consist. $0.20 less???

Use diesel kleen in your truck keeps everything from cloggin up...as far as cavitation goes I dont think it is a big issue with these newer trucks...someone that knows more than me will probably answer that a little better than i can

I have heard that with the 6.0 Ford doesn't recommend even changing the coolant until 100k. I have never heard of anyone having cavitation problems with them so I guess they fixed that problem.
WWBeast is right about the Diesel Kleen. I have run additive in every tank except the first and mine runs like a champ.

The short answer to your question is yes there is cavitation, but that is true of all diesels. But in your new truck, no need to add SCA's as your coolant has a long life additive to prevent damage from cavitation. Just change it with the specified YELLOW coolant as directed. Don't mix coolants and DO NOT ADD SCA's it will neutralize your yellow coolant additives. No reason to cheap out and save $20 on coolant and destroy a $5000 engine.

I think the lower compression of the 6.0 reduced cylinder wall flexing, and the need for SCA's

Lower compression? The 6.0 runs 18:1 compression... the 7.3 ran 17.5:1.
No additives are needed as the coolant has been improved, probably since many people didn't remember to dump the necessary additives into the 7.3.

Actually, Ford was one of the last manufacturers to adopt long life no additive needed coolants for diesels. Caterpillar uses OAT as do many other makes. So I'm not sure where you get the strange idea that no one else uses it. Again, these coolants do not mix well with each other.

So if everyone switched to these long life anti freezes there would no longer be a market for SCA additive? Just switch to long life, and eliminate that bothersome maintainance routine? Save time, and money?
