Review on 🔧 Irontite Additives Set - Thoro-Flush, All Weather Seal, and Ceramic Motor Seal (468-9190-16) by Eric Ross

So far so good. (I hate to say this because I've jinxed Jobs before.) But I have to say that applying this product to the Ford Expedition required LESS work and effort than I thought it would. (It helps if you have a vacuum pump and tank to drain the system after the ceramic treatment.) All in all, I'm glad I took the advice of an older mechanic (my father-in-law) who remembers that he has successfully used these products. in his machine shop a few decades ago (like half a century ago PLUS). I'll see how this car holds up and post a report in a few months. A few years ago I had a North Star Cadillac that had blown head gaskets and overheated due to a design flaw caused by stretched head bolts (original design). was for hardened studs and nuts, but GM designers are smarter than the original designers) and I'm glad I ventured into machining and installing hardened studs in this application. With this Ford Expedition, I have a lot more hope. We'll just see each other.
