<font color=blue>If you do have to add anti-freeze, make sure it's for diesel engines</font color=blue>
Okay, Mike. I'll bite...
What makes antifreeze different for diesels than any other engine? Is the cast iron in the block any different? ..or the aluminum parts? ...or is it high compression anti-freeze? /w3tcompact/icons/smile.gif I think someone is "pulling your leg" on this one, but hey, I've been wrong before.

It has additives to prevent cavitation. <A target="_blank" HREF=http://www.tractorbynet.com/cgi-bin/compact/showthreaded.pl?Cat=&Board=oil&Number=173168&Search=true&Forum=All_Forums&Words=cavitation&Match=Entire%20Phrase&Searchpage=0&Limit=50&Old=allposts&Main=173168>Here's</A> another thread that discussed this a couple of months ago.

Mike, I stick by my previous assertion that for our tractors, there is no need to put in additives. As a matter of fact, my TC45 owner's manual only specifies winter/summer coolant at a 50/50 mix. What it does say is to drain and flush the coolant system on an annual basis. I did this as a result of busting a hose, but otherwise I'd probably not noticed it in my manual. Also, TSC sells their own brand of antifreeze (Traveller) which has the following notice:
Meets or exceeds these specifications: ASTM D-4985, Caterpillar, Cummins 90T8-4, Mack Truck, John Deere H2481, H24C1, and SAE J1941.
This antifreeze also has corrosion inhibiters and defoamers. I do not know this for a fact, but I would be willing to bet that all major brands of antifreeze meet the diesel manufacture's specifications. If you are in the antifreeze business like Prestone, you are sure not going to miss the segment of the market driving diesels. It's my opinion that you can find someone who makes an additive for almost every kind of fluid you add to a tractor. You'll also find folks who use it and say you "gotta have it." Since my owner's manual doesn't call it out, I'm not going to use it. If your manual says you should use it, by all means, use it as prescribed.

Actually, I'm not sure Prestone sells a diesel-specific antifreeze, but link with an explanation for why there's a special antifreeze for diesels with wet sleeve liners. If the antifreeze meets the manufacturer's specs then it's the right one. Since I can't remember all the specs, I just pick up a gallon of FleetGuard. I know it meets them.
Correction: I received an email back from Prestone and they said;
Yes. We do make antifreeze coolant for the Specific Diesel application. This product is called Prestone Heavy Duty Antifreeze Coolant (AF-977 HD)

Well Mike, I've certainly learned more about antifreeze than I ever thought I would, but there are still a couple of questions I have to answer before I give you full credit and sit down to eat my plate full of crow. /w3tcompact/icons/laugh.gif I'm wondering if our under 2-liter diesels are the "heavy duty" engines talked about in the specification, ASTM 4895, and also if we have pressed in wet sleeve liners in our small engines. I'll have to go to my repair manual to find out unless someone knows this and "chimes" in with the info. You might say that the Fleetguard antifreeze is good for everything, but Cummins has stated that the Texaco extended life coolant (TELC) may be causing problems with silicone seals. What's that all about? /w3tcompact/icons/shocked.gif Does the Fleetguard and Texaco coolant use the same SCAs?
So, you are absolutely correct that there are special formulations of antifreeze for heavy duty engines. I didn't know it, but now, thanks to you, I do. I'm just still not sure their application is needed. As I said before, the TSC Traveller brand meets ASTM D4985 and it doesn't cost a fortune. If I use that and change antifreeze on a yearly basis as suggested by all manufacturers, I'll probably never see a coolant system failure associated with antifreeze. What do you think?/w3tcompact/icons/eyes.gif

I wondered about these 2 items too. I did a little searching on NH, JD and Kubota sites. The only one that mentioned sleeve type was JD. All of their Compact Tractors, up to the 4710, use cast in block liners and not wet sleeve. Their Utility tractors are the first class that uses wet sleeve liners. So, maybe we're both right, there is special antifreeze for diesels, but compact tractor owners don't need to use it. /w3tcompact/icons/smile.gif
