Hello, My car gets hot really fast now. If I start it up for a minute or two, the gage is near 225 so I have to turn it off. I have the cooling fans set to run at all times and I also have an overheat protector from DMC Joe on it. I used to get a ssssss noise when I removed the overflow cap but I no longer do.(when it stayed cool) someone mentioned the water pump. how can I test it to see if it is working correctly? the system is full of coolant and I have about an 1-1/2 inches in the overflow bottle. I checked everything out and I dont see any leaks. any ideas on what this could be would be greatly appreciated. Thanks David
