'04 Series 60 getting fuel in my coolant

Lame-hopefully it will be a fairly quick job once they get around to it, I know that's frustrating though.

 

If you are using DCA4 coolant additive that is the cause of it eating the copper sleeve.
Just a thought!

 

The additive eats copper? What kind of additive should be used in these engines?

 

I had same on mine. 24 h in the shop and 1700+tax bill

 

I have opened a lot of engines and the best at reducing liner pitting and the internal corrosion of Aluminum and Cooper is Nal-cool, Power-cool. I became a believer when a customer drought in his truck and had us do a flush, and add Nal-cool to his near new 3406B, these trucks hauled chips and went 22 hours a day two trips over two mountains, each way. They had a head gasket failure at 700,000K which was totally normal. We had multiple engines apart at the same time all the time cutting the blocks to lift #4, 5, and 6 liners and having the head modified to get more coolant flow. To do that you have to remove #3, 4, 5, and 6 cylinder kits. When I removed the ones that had DCA4 they were pitted severely, heavily corroded at the upper band area and lower seal area, and coated in green slime at the top of the liner area. A completely normal finding.
The ones with the Nal-cool were like new with very little pitting, and no corrosion in the seal area. The water pump cover that we regularly replaced, as a normal replacement item was like new, the thermostat housings were not corroded.
I was very impressed, I got a bottle and added it to the wife's Caprice, it is a 1993 305 with an aluminum rad the original one. I, and 90% of all original equipment dealers use Dex-cool, Power-cool, or Nal-cool, coolant. You really want a filter, to get rid of the sediment that is in all new units, and from coolant additive drop out. If it is an older unit it takes a long time to clean out the scale, green slime that is in the system and you need to do a flush with restore to help the process along then use Arm and Hammer Washing soda with a little Dawn dish washer soap to clean it out. When it comes out clean, do a couple of flushes with clean water, then add the Coolant. You buy test strips, cheap and replace the filter with either a additive package or a 0 filter.
I have seen newer trucks with DCA4 corrode out the injector tubes in a year in N14's, and Cummins did not want to cover it even though it was their engine and coolant additive.
Just a thought!

 

Wow, that's crazy. They should've been able to do a whole inframe by now. I feel for 'ya.
