I have replaced my thermostat,put all new hoses,and it is not leaking any where but when I go about a mile down the road it jumps hot in a split second I can't figure out why because the thermostat is not sticking it is opening right when it heats up like it's suppose to and I flushed the radiator out.Any ideas what it could be????? And water pump is working right it's pumping water but still getting hot.
