Is it normal for coolant to evaporate over time? A little less than a year ago I did a flush and fill of my cooling system and now I notice it is about two inch's low! Now I'm not sure if this happened all of a sudden or has been going over time and I just didnt notice till now, but could there be any other place for it to be going?

(PS there is no oil in the water)

 

Maybe check the weep hole on the water pump...I had an old mazda and coolant was disappearing. I could't figure out where it was going but it was slowly dripping out of the weep hole because the bearing in the WP went out.

 

Fill it back up, and see how if it goes back down anytime soon...

 

are you low in the rad or the overflow tank?

 

Overflow. Radiator is to the brim. Does this make a differance? If its there its there not its not right? No?

 

as long as the rad is too the full mark, youre ok. the antifreeze water mix should not evaporate quickly, but over time it will. and the overflow tank is just that, overflow. on my torino there isnt even a tank, just a drain hose! make sure the rad is at the full mark, then add a 50/50 mix of antifreeze to the overflow until its at its mark. for 99 you probably still use the standard green coolant.

bottom line is, your ok
