i am a pizza delivery guy and i rely on my car both day and night because i put almost one hundred miles on a day. here are some of the problems that i have. i have to constantly put antifreeze in it. not alot but enough that i have to buy a gallon a month. now, there isnt any in the oil, the exhaust condensation isnt antifreeze. i can sorta smell the antifreeze smell after running it for a while. im thinking maybe it could be the radiator cap, but not positive. another problem i have is my a/c just up and quit working, worked fine all summer and then just died. the engine races with the air conditioning on and races to 2,000 rpms and stays there until you turn it off. thanks for the thoughts and the time to read this guys...

 

your water loss is probably coming from your thermostat housing. the ones installed on cars after 1998 are made of cheap plastic and break at the gasket then slowly leak out the coolant
