    I have a 2000 Escorts ZX2. The temperature (I have had it for a month and it has been sitting in a gaurge for a year with previous owner) take a while to heat up. The heat and A/C works normal. Any advice will be appreciated.

    My 1992 Escort also takes a while to heat up.
    Actually all of the cars I have owned took a while to heat up.

    Does the coolant look green? Is the heat hot?

    My zx2 takes a little while to warm up and I just replaces thermostat and cooling and flushed system.

    Give us a temperature, wind speed and rough estimate on how long it takes. What you're discussing could be normal.

    Have ooened up the cooling ststem at all recently. May have a air bubble or blockage. I would flush system and chenge thermostat for beginners. Very simple to do.

    Well the temp gauge barley stays in the normal range. For the gauge to reach normal level I need to get on the interstate and stay at 65mph for a for minutes. once I get off the interstate and drive for 2-3 minutes at 25-30 mph the temp gauge drops below normal.

    From the symptoms I would think the thermostat could be stuck partly open; i.e. not closing all the way. But then I dont know how that 'bypass' thing works.
    With my 2nd gen thermostats, if you have one of them off the car and shake it, you hear a soft rattling sound.

    Flush the system with a garden hose. You may try running a warmer thermostat

    The OEM thermostats were 190f I believe. If the cooling system is okay, it will handle that temp with no ill effects; regardless how hot the weather is.

    At least once each year, on some toasty warm day in the spring, I start up each of my Escorts and let it sit idling in the driveway. The purpose is to let the engine get hot enough for the radiator fan to cycle on once or twice. If the fan is not going to work for any reason, I dont want to find that out while sitting in a traffic jam in some Metro area, or being in the line of cars creeping back across an international bridge from Mexico into the USA.
    I stay close to the car until I hear the fan come on, then I check the temp gauge; to find out where it is pointing when the fan starts. That gauge reading will vary from one Escort to another, but should at least happen consistently per vehicle.
    I have replaced the radiator fan motors on three of my Escorts, the first time because a bearing in the motor had failed, and later because the prices of replacement motors (or the entire fan and shroud assembly) had dropped greatly.

    I visited a (dirty) mechanic to have an exhaust flex pipe welded on. He saw that my gauge was reading cold, surmised to himself that the head gasket was probably blown, (common for early bimetal engines of the era,) proceeded to lift it to maximum height on the lift, then let it idle until the fan came on... which was at least 30 minutes. I knew what he was doing. I just stood there, right outside the bay door and watched him... for at least 20 minutes. He didn't say a word, I didn't say a word. I knew it ran cold and it would take forever for the fan to come on; I just wanted to see how patient he was. :whistling: Well, my patience was about five minutes from running out when the fan finally activated. Only then did he move to bring the car back down. Needless to say if it were going to overheat, short of having stilts, no one would know until it started spewing coolant.

    I don't visit a mechanic unless it's tires, paint or welding. (or warranty work) Since that time I've learned the magic words: "NO INSPECTION"

    This condition... increased airflow over the radiator, typically results with the opposite reaction. Quite odd. The temp and RPM seem to have a direct correlation, regardless of the airflow over the radiator. I'd be interested in verifying whether the gauge is reading accurately. Do you have or can borrow an infrared temperature reader... point it different parts of the engine and at the (non-reflective) metal parts of the thermostat?

    It was otherwise physically intact?
