I have a 2000 ZX3, about 3 weeks ago I had the AC charged, they put the dye in to see if there is a leak etc. Since then the water temp. gauge in the dash, goes to the red while my car is idling, When I drive the car it starts to level back out, but is not going into the red and past. I checked to see if the coolant was low, or if there were any leaks that could be seen, nothing. I have about 96,000 miles. I replaced the water pump, I have never replaced the thermostat or had my radiator flushed. What would you recommend? Is there anything I can do on my own.

Re: Water temp gauge going into RED
The ac work that you had done wont do that,start the car ,let it run for a little bit,with a glove on,or a rag squeeze the top radiator hose ,once its full of pressure,when you see the fan go on it should make the hose soft,meaning the thermostat opened,if not change the thermostat,if the fans go on and your thermostats open,you have to have the radiator

For the gauge, replace the thermostat. For the A/C it could be low on freon. Parts stores will put freon in for you. Use at least one can with dye in it. If it goes low again fast. A garage can find the leak.
u need a leak test done-they put a dye in system then take a light to it--ur probly empty--compressor cud be bad too--bring it to a pro to hook up gauges--put in' ice 32 brand coolant' and u nevr hav to worry about it again
Pep Boys, Autozone, Advanced Auto, Napa, most all the major auto parts stores carry a recharge kit...a few Wal Marts even carry them---Or you can buy them online fom Amazon, Ebay, etc...
In most kits you'll find a can of refrigerant, a flexible rubber hose and a pressure gauge. Follow the instructions in the package to assemble the pressure gauge part of the kit. Usually you'll have the hose already attached to the gauge, such as this one.
Heres the problem, this car holds a total max amount of 25oz of feron (1lb 9oz). you dont know how much is in the system now and without gauges to read the highside and lowside you wont know how much to add, they sell the gauge with the yellow and green and red display but its not accurate. you just dont keep adding until its cold because will will damage the system. the right way is to have a certified ac tech to check and charge the system. there could be a small leak somewhere. to recarge the system correctly it must be evacuated and then vaccumed down then depending of how low the system is you add the right amount of oil. then you add a dye and the correct amount of freon to the system. the dye thats added is used to find the leak. when the system gets warm again there is a blue light and yellow glasses used to located the dye which will be where the leak is, after recharging and testing you then use a freon snifer to check all components and hoses for leaks. if this is something you cant afford at this time then you can try to recharge yourself but take note that just because the compressor is not on means its low on gas. make sure to get the little gauge the sell and read the directions so you dont overcharge the system. also dont use the sealer stuff they sell, only buy the freon with oil and dye in it and dont vercharge, watch the gauge they give you, you will be charging from the lowside which is the small valve, the hose will not fit on the highside, good day.
No , but whoever did your A/C probably put a Dye in the system to detect any leaks, an it is green, which is the same color as most coolant/antifreeze.. But if your coolant level is not getting low, i wouldn't worry about it, because it is probably the Dye. Now if your coolant level is getting low, you may want to have the system pressure checked.. Good Luck.. Also it may be your Heater Core.. On some vehicles, the heater core, an the evaporator( where a/c leaks), or sometimes in the same casing unit. But again, you will need to have your coolant system pressure checked..
To be able to find the leak,for sure,is to have some UV dye put in with the freon,then when it leaks down,and stops cooling,the mechanic can find the leak with a UV light,and glasses.The dye you buy to put in yourself,like red,or what ever is a waste of time and money,you will never see the leak.If this was at all helpful,please rate,thank you.
This one is a difficult one to say. You could have a bad ac unit on the cars engine. Also when it goes back to 72 degrees your car is just displaying the temperature inside the car one of the features of a digital adjustments on these types of cars. Also you could have a leak and therefore not getting the cold air you wanted.
