a few things you should know when you change antifreeze you need to drain and flush the system
so you dont end up with with a mix of old and new ,mixing the two will decrease the life of the new
there are three types of antifreeze
1 conventional [with ethylene glycol base with inhibitors added}
this protects from freezing,overheating,rust and corrosion for the modern engine
2 extended life antifreeze {ethylene glycol base with carboxylate additives}
the only thing that is diferent are the additives for a longer life becouse of
the breake down process are slower and extend the life of the antifreeze
{note both 1 and 2 are harmful or fatal if swallowed or inhaled.
3 and a non-toxic antifreeze that doesnt containe propylene glycol and additives
for controling ph and corrosion
Antifreeze additives do several things:
They can act as buffers to control the PH of the coolant.
Corrosion inhibitors protect the metals in the cooling system.
Some additives reduce foaming.
There are also certain additives that prevent cavitation and tiny bubbles.
These Additives Have Some Drawbacks:
The antifreeze it self does not break down but its additives do. All of these additives have been in use for many years but they do have some drawbacks.
The additives are unstable and deplete fairly quickly:
The Ph buffers and corrosion inhibitors are depleted sometimes in a matter of months.
Some additives break down and come out of solution. The silicates can polymerize and form gels.
Insoluble Salts from the phosphate and silicates are formed and attach to the interior surfaces of the cooling system.
As these deposits grow thicker they act as insulation, which decreases the heat transfer efficiency of the cooling system.
Silicates in solution can become abrasive to water pump seals.
Conventional AntiFreeze
Conventional antifreeze has an ethylene glycol base. It uses some combination of the above additives and their drawbacks. It is harmful or fatal if swallowed or inhaled. Also animals seem to like it and have been known to drink it if left out. Some of the problems of the additives can be addressed by using different formulas (combinations of the old additives). I use antifreeze that is labeled as a low silicate formula. There are also antifreezes that are non-silicate formulas.
Extended Life Antifreeze is completely free of Silicates, Borates, Nitrates, Nitrites, Phosphates or amines.
There may be some problems with Extended Life Antifreeze in old vehicles!
When you change to extended life antifreeze there is some evidence that you could do more harm than good. They say that residue silicates and phosphates still in the system could coat the inside of the cooling system and act as insulation which decreases the heat transfer efficiency of the cooling system. Probably the best approach is to use a traditional antifreeze, the type the system was designed to use.
what ever you deside to go with is up to you just remember to look and see if the color is right if it has lost its color well it's time to change it
thought you would like to know this and I would like to thank "Richard Bahnke at Texaco Products" for help on this info
hope this helps some of you and sorry so long winded
