<FONT face="Times New Roman, Times, serif" color=black size=2>I have a problem with my heater, When i turn on the fan it starts to blow cool, like im sucking all the warm air out of the heater core and there is not enough water flowing in the system. I did have a problem with the cooling cap leaking out water but i replaced that so im not leaking any water out of the system anymore. Oh by the way we just had some cold days and snow and when i replaced my radiator last summer i guess i didnt put any anti freeze in the system and i did get some freezing in the radiator but no apperent damage because of early statment of no leaking , any help would be apreciated. </FONT>
