Talk:Antifreeze

message: This page is all about automotive (blue) antifreeze. There's also pink RV antifreeze which is a non-toxic antifreeze and used in eg plumbing in boats and RV's when not in use.

replies: text:  BioImages2000, don't bother make changes to this entry, because the f***-wit moderator (Wtshymanski I'm guessing) that think they own this entry will revert it at a wink. I added well considered carefully placed information regarding three common (automotive) glycol antifreezes / additive packages which are ALL incompatible with one another (IAT, OAT and HOAT), what happens should any be mixed - sludging or jellying that blocks heat exchanger cores and narrow passages. Also that colour of the die is ABSOLUTELY NO INDICATION of the type of antifreeze. It was reverted in minutes. BTW, there are other variations on the three above packages. In the end, there is no easy way of identifying compatibility without knowing exactly the installed product / manufacturers technical advice (flush and replacing may be the safe cheap option). They even use pretty much the same stuff for ground deicing of aircraft. Please see my comment below about moderator reversion. Whoever is doing it is a James Hunt (Rhyming Slang).  — Preceding unsigned comment added by 81.141.151.243 (talk) 18:44, 23 October 2021 (UTC)

thread_title:  All about "blue" antifreeze. 

message: What f***ing d**k-wad moderator is reverting edits to this innocuous article which give brief, pertinent and carefully placed information regarding the dangers (to equipment) mixing any of the three most commonly used automotive (and other applications) incompatible Glycol antifreeze types (IAT, OAT and HOAT) that causes sludging / jellying (blockages). People using Wikipedia for a subject like this are most likely interested in the pit-falls or to understand the many caveats Antifreeze and equipment manufacturers give, extolling their products while warning of danger, mixing incompatible product (for fear, uncertainty & doubt - FUD to boost market share / sales). I spent several hours from many sources to understand the reasoning for not mixing the different glycol antifreeze formulas. S**t-for-brains moderation like this is why I will never ever financially contribute to Wikipedia, and probably why so many people find this supposedly open encyclopaedia an absolute slanted waste of time. Whoever you are, may you rot in hell, you sad, sad git. Get a life!  — Preceding unsigned comment added by 81.141.151.243 (talk) 18:03, 23 October 2021 (UTC)
thread_title:  Moderator Reversions 

message: A general guide to vehicle Antifreeze (colour does NOT necessarily indicate type!) different manufacturers use various colour dies. Never ever risk mixing different types (IAT / OAT / HOAT) or go by colour when topping up, it will cause chemicals to form sludge or jelly that block passages. If in doubt, flush and install manufacturers recommended, strength etc. Note that some manufacturers (e.g. Comma) do not label their products terribly clearly such as "Comma Super Coldmaster Concentrate" (Blue) which is in fact mono ethylene glycol IAT.   The three most common types of antifreeze are...
:OAT Inhibitor Antifreeze-
::1998 onward vehicles use propylene glycol base (less toxic) with Organic Acid Technology (OAT) inhibitors. Often Red / Orange colour. Typically offers good corrosion protection, 5+ years 100,000+ miles. No silicates, nitrates used in IAT phosphates in IAT banned by EU. Even after FLUSHING, HOAT SHOULD NOT be used in systems calling for OAT.
:HOAT Inhibitor Antifreeze-
::Propylene glycol base with HOAT - Hybrid Organic Additive Technology has a special cocktail of inhibitors (OAT and small number of IAT silicates) though still can not be mixed with either. Often yellow in colour. HOAT silicates protect against rust. After FLUSHING OAT will work fine for systems calling for HOAT. HOAT coolant used in certain systems from 2002 on. HOAT, often referred to as "global, meeting / exceeds G-05 specification and G-11 or G-12 Volkswagen and Audi". Typically replaced after 3 years.
:IAT Inhibitor Antifreeze (older vehicles) - 
::Cars prior to 1998 usually use ethylene glycol (pretty toxic) with Inorganic Additive Technology or IAT, containing silicate / nitrite inhibitors (phosphates banned by EU). These additives protect various different metals and seals etc. used in older cooling systems. Typically replaced after 2-3 years. — Preceding unsigned comment added by 81.141.151.243 (talk) 21:07, 23 October 2021 (UTC)
