Re: truck take forever to heat-up Top Post.... Hers one for ya...What is the ratio of coolant to water in your system...If you have more water in freezing weather it will slush up....Deending on the ambient temp outside pluse the windchill factor.......you may only need to flush your system and replace the coolant using aroung a 80 to 20 mixture 80 being coolant 20 water...Unlike popular belief you need water to activate the antifreez..thus keeping it from freezing or slushing up.....Its like the salt thing where you throw salt on ice it melts...ok but it has to be above freezing to do so right because it will just keep freezing what it melts....

May be that the ending unit is not reading right, had it happen to me, didn't think it was right that the truck was only running at just over 150° in the middle of summer. See if there's some other way of reading the temp., or replace the coolant temp. sending unit. Mike, Working off gauge on dash. Bottom line though, takes forever to warm-up, to put out heat. I don't need a gauge to know that I'm freezing! I Do though believe the gauge is close enough, it does seem to corespond to temp of the thermostat, once warmed-up. Thanks, Mr Ranger
Hi, I'm new to the group but thought I'd put in two cents worth here. There are properties of liquids known as boiling point elevation and freezing point depression. These properties are evidenced when two liquids that are mixed together have a lower freezing point and higher boiling point than either of the original liquids. The freezing point depression property is what is happening when antifreeze and water are mixed in the cooling system to protect it from freezing. Additionally, freezing point depression is also shown by adding soluble solids to a liquid; adding salt to water is an example. If one looks at the charts in the link provided by The Nolalu Barn Owl,

one will see that the Methanol/Water Mixture chart shows the effect. In regards to a jug of antifreeze freezing or not, the actualtemperature at which the antifreeze in the jug will freeze is determined bythe concentrations of various components. Unless the antifreeze consist ofone pure component the freezing point will be depressed from the freezingpoint of the primary component(s). Loyd
