My first guess would be that your water pump is not pumping an adequate supply, check the serpentine belt to see if it's extremely loose. If you have a '94-900 and you have not changed the belt or upper idler pulley in 50K miles, you should probably replace them. However, unless the belt is very, very loose, (problem with tensioner) you probably have another problem. I think you'd see other problems if it was that loose. Does the coolant get used up every time you run it ?
