<div> <font size="2">Engine coolant temperature will be determined by the thermostat and the radiator cap relief pressure. <br>
</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Also depends on the ambient temperature and heat from the engine, cooling side fouling, the heat transfer around the radiator. <br>
</font></div>

</font></div>
<div><font size="2">Ideally the overflow tank should be large enough to handle the volume change of the coolant from cold to hot. Typically this is about a quart and tanks are usually 2-3 times that. <br>
</font></div>

</font></div>
<div><font size="2">Do a good flush, Run on distilled water for a bit so scaling is removed, drain, then fresh antifreeze mixture. <br>

<div>Will increasing the size of the radiator overflow tank increase coolant volume, thus help keep temperature cooler?</div>
<div><br>
</div>
<div>Thanks!</div>
