I have replaced the engine temp sensor and the thermostat. The temp gauge goes up to halfway or a little above when idleing and the cooling fan does not come on. The fan works if I turn on the AC. What kind of problem do I have and do you think it could be a water pump and if so ho do you test it on a sys tem like the saturn without a radiator cap. thanks
