Antifreeze/Engine Coolant

TWINKLE_TOES · Nov 11, 2001

Patrick and John,
Thanks for taking the time to enlighten me further. Pat is right, not much to be found in the public domain (excluding TBN /w3tcompact/icons/smile.gif) I have some failures in high speed centrifugal pumps where the pump housing has been breached in the area of the impeller. The fluid is jet A. At first glance it looks like gauling as a result of mechanical failure. A closer look reveals a surface texture with wavelets around the perimeter of the impeller and the housing and very highly polished surfaces. Looks nearly as bright as electro polished aluminium. Many thousands of these pumps are in service but only two have experienced this problem./w3tcompact/icons/frown.gif

Here is a tid bit I got from my dealer last week. A couple of weeks back the dealer was having a presentation on JD parts and supplies. I wanted to go but could not. I called my sales guy last week on another issue and we started talking about the presentation. He said that the biggest problem that JD sees is caused by not changing the coolant on schedule and with the correct product. The dealer certainly knew about the problem caused by using the wrong type of coolent. He said they had a cylinder with the pitting as well as a hole(s) going through the metal.

FYI,

Check out the peak antifreeze site, www.peakantifreeze.com . The technical discussion talks about fleet charge. According to that you still need to perform sca maintence. What is that, add sca or replace antifreeze?

Does sound like you could use it in everything. Do the sca's make it a wetter antifreeze?

That's the first I've heard that you need to keep checking it. I use Fleet Guard and it doesn't say anything about having to check it all the time. It's not a wetter antifreeze but it's just additives to the antifreeze to prevent the cavitation effect.

I talked to the tech guy at Fleetguard this week and he said that you do have to chech it a few times a year. I run ES Compleat in my '95 PowerStroke. A convenient way to get samples to perform the check, and to enable flushing when you do change it out, is to add a John Deere coolant eye. It goes in-line in a heater hose , like a Prestone flushing tee, but sooo much more. = : ]

Yea they also have an inline filter that will release the additive into your antifreeze as well. That is the setup that Navistar has on the Ford engine in all other apps. For some reason Ford deleted that setup when they put the powerstroke into their pickups. Ford now has an ELC that they put in them.

What's an ELC?

ELC=Extended life collant

**Last I read Ford said No on the ELC on the powerstrokes. I have 1997 and Ford only likes the green stuff. I have no idea about 2002 models though.

I would check the SCA levels every 6 months. Cheep and easy.

Thanks
Mike

Mike,
Ford came out with an ELC this year for the powerstrokes. It's orange.

Thanks Richard. I would only hope that Ford is on the ball with coolant issues. Too bad 2002 is the last year for the 7.3 DIT. Then ford will be back to square one when they release there new 6.0 engine. Ford loves to stop making engines that work.

You are correct about Ford deleting the filter data from their books. Then they wondered why 60% of the 7.3 L diesel had liner problems.

**Orange ha...I guess they did not like the blue and purple coolants that Fleetguard has /w3tcompact/icons/cool.gif

Thanks
Mike
