    Get one thing fixed something else happens....

    OK today when I am driving home my temperature gauge starts to head towards the red. This has never happened before on my ZX2.

    Luckily I'm not that far from home. So I crank up the heater and I make it home. When I turn on the heater full blast the gauge did come down a bit. Does this mean that its not the Thermostat?

    I am having a small leak of antifreeze I am unable to locate. I think its coming from the water pump but not positive. I was planning on having that changed with my new timing belt next month.

    Could this issue still be just the Thermostat? or the water pump failing? :|

    Replaced thermostat today.

    I haven't had time to road test it but while idling it will go towards H and then come back to the middle.

    Before the over heating started it stayed in the center of C and H all the time.

    Fixed.

    Any tricks in finding a coolant leak?

    If you can't find where it's coming from there are a couple "tricks" to help track a leak down. I have a stant pressure tester that you hook up to the radiator and pressurize the cooling system to try and reproduce the leak without the car running. This will usually show the leak. You can "rent" one of these from most parts stores, you pay the full price and then get a full refund when you return it. They also make a dye you put in the coolant and use a black light to find it. I've used this with oil before and worked great to find a leaking intake gasket.

    Check your hoses and also look around the radiator. The side tanks are plastic while the core is aluminum. Coolant is notorious for small leaks around the seams from expanding and contracting during the lifecycle of the radiator.

    It hasn't been leaking lately for some reason. The only thing I did was replace the thermostat. I thought I saw some fluid coming from the water pump area. I am assuming its a gasket on that. I am going to replace the pump and timing belt here in a couple of weeks. Hopefully that will fix the mystery.

    How much fluid was trickling out of the water pump?
    Is the pump getting noisy?
    The temp gauge can be tricky on our zx2's.
    Car can show serious overheating on the gauge when its only the temperature sensor,located underneath the thermostat housing.
    In fact its a very common,cheap to fix problem.
    Another leak prone area is the plastic thermostat housing,easily cracked when replacing the thermostat.

    I'm not sure exactly where the leak was coming from. However, it was in the area of the water pump. I had to add fluid weekly but not much. It stopped after I changed the thermostat.

    I changed the water pump last weekend. And the o-ring was in bad shape. Hopefully after I finish installing the timing belt there will be no leak.
