DCA\'s in TC\'s

Can anyone tell me if the engines in the Class Boomers have wet sleeve cylinders? Believe it or not, my dealer doesn't know if SCA/DCA should be added to the coolant like on a Powerstroke. /forums/images/graemlins/blush.gif I really don't care to drill pinholes in my cylinders due to cavitation. /forums/images/graemlins/mad.gif

Directly from the New Holland web site....
48hp - 55hp - The parent-bore engine design eliminates sleeves and the risk of seal failure. The cylinders are cast as an integral part of the engine block, providing added strength and rigidity.

If the 48 - 55hp models do not have sleeves, I can't imagine the smaller ones do, but it's not stated on the website.

Mike; They've ALL got class, but I meant the Class III's. /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif

None of the Boomers have wet sleeve cylinders. If you check your Operator's Manual, you will see the recommendation is for Permanent type antifreeze. If you do a search, you'll see that the proper antifreeze has been "cussed" and "discussed" in great detail in many forums. It's really your choice, but your engine does not have wet sleeve liners.

All right.....I'll bite. What are wet sleeve cylinders ???? /forums/images/graemlins/blush.gif

Re: DCA\'s in TC\'s

I'll try, someone will chime in if I'm off I hope. With wet cylinder sleeves, the cylinder is not an integral part of the block like in many gas engines. Instead the cylinders are inserted in the block, somewhat like valve guides used to be. The problem with this is that as the engine combusts the fuel/air mix, it sets up some sort of harmonics that causes the miniscule air bubbles in the coolant to act somewhat like tiny drills boring their way thru the cylinders until the coolant leaks into the combustion chamber when the engine is shut down. This causes "hydro-lock", in extreme cases the engine sometimes can't even crank over, we all know liquids don't compress. DCA/SCA are additives that prevent the "cavitation" from drilling your sleeves. They are cheap insurance. In some of the "big" trucks, there are sometimes coolant filters that a pill of DCA/SCA can be placed.

Somebody chime in if I didn't quite get it! /forums/images/graemlins/grin.gif

Jim; Thanks, I couldn't decipher that for some reason. Well, what can you expect from me, I'm only a misplaced carpenter! /forums/images/graemlins/grin.gif

Re: DCA\'s in TC\'s

Whether or not an engine is sleeved does not preclude it from cavitation erosion. Ford tractor (parent bore) diesel engines from the early 80's are the best evidence. Antifreeze with DCA additives should be used on all diesels. That is my recommendation. It may be worth what you paid for it.
