The waterpump on my nissan 200sx is just about shot. The car is a 95 and runs great when it runs right. It has had a very minor leak in the waterpump for some time but all of a sudden it just dumps the water when i turn off the car or if im stopped to long, when its running it retains most of the water. Well, what im really trying to figure out is how much a shop might charge to replace it because i simply don't have the time. I usually do all my own work, changing axels, and clutch and what not. Also could it be just a seal and be able to put some sealant on it to stop the leak. I would love to get it fixed quick seeing as its getting cold and i would like to warm up my car in the morning.
