I just had my waterpump replaced with a genuine gm water pump in my 97 Corvette. It appears to have been replaced with the 2004 version going buy the shape of the thermostat housing. On the freeway temp will start out at 198 works it way up to 208-210 work its way back to 198 stay at 198 for awhile and work its way back to 208-210 and so on. Before the new pump was put on, it would run at a steady 189 to 196 and stay there. What could cause this?
have the same problem?
