My 98 catera is leaking water.
For two weeks no visible leaks could be found, but the radiator resivor was going down about a pint per day. Recently, when I stopped, water would drip from the front right side of the radiator area. I check the hoses and all appeared well. Today water was pouring out of the same area when I parked after about a 15 min. drive- it lost about 1 gal. of fluid. But about a half hour later after a similar drive no leaks were detected. The water dash guage has never indicated excessive temperature. Is it likely a water pump or a crack in the radiator? The car has 68,000 miles. What is it likely to cost to replace each? Thanks.
