[QUOTE="RubiconFreedom, post: 425805, member: 18741"] Follow Up: Just wanted to add, that I'm concerned with others who have this same issue. One way the fluid doesn't drain, could be due to the mixing of HOAT with OAT coolants. Mixing these coolants would cause a chemical reaction that turns the coolant into a gel, crystallizes then hardens. If the coolant doesn't flow as it should, then one could have this chemical reaction or metal/rust fragments in the system. I'm leaning towards the chemical reaction of different coolants. [/QUOTE]
