Racecorr Posted January 16, 2018 Share Posted January 16, 2018 Hey fellas, just to give you guys a little refresher, 07 E7 AC I've had 5 radiator failures. I've had an in frame done with new liners, pistons, and 2 new heads, a new EGR cooler, new air compressor, updated expansion tank, and countless bits of advice. The one thing I found intriguing was someone suggested that a blocked oil cooler screen could be the culprit, I had my mechanic check it out and he told me that the screen was about 15%-20% blocked. My question, is that enough blockage to cause all of these radiator issues??? Quote Link to comment Share on other sites More sharing options...

Well, not really a push, because it hardly ever pushed out of the cap. It's more like a surge or something that is causing the radiator to "bulge" and split open.

fjh Posted January 17, 2018 Share Posted January 17, 2018 (edited) Are the proper stats installed should be a 185 and 190 stat in there to eliminate the hammer of both stats opening at once! Just a thought Edited January 17, 2018 by fjh Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted January 17, 2018 Share Posted January 17, 2018 (edited) I still say you have a shop towel wedged somewhere. I have seen it done here locally. A guy put 3 new radiators in himself, they kept splitting. The fourth one Mack dealer put in and found a shop rag stuffed in a coolant line. The guy stuffed a rag in there to keep debris out while he swapped radiators. Edited January 17, 2018 by Dirtymilkman 1 Quote Link to comment Share on other sites More sharing options...
Racecorr Posted April 29, 2018 Author Share Posted April 29, 2018 Well fellas, after a flush that produced about a cup of some unidentifiable scale, and a new oil cooler inlet screen, my truck has been running the last 2 months with no problems. Thanks for all your help. Quote Link to comment Share on other sites More sharing options...
