Message: [QUOTE="PSDEng, post: 848133, member: 1228"] I've heard the same thing. I've been running the Fleet Guard red ELC in my truck for about a year and a half now. I was working on my truck last winter and my buddy seemed shocked that I had red coolant in it, which got me a bit worried. He gave his co-worker a call (who supposedly has been through tons of International training), and said as long as it's phosphate free (or maybe it was silicone free) that I should be ok. I remember the fleet guard bottle stating that, so I just figured I was alright. [/QUOTE]
