I am not familiar with the Audi, but on most cars, the thermostat is at the point where the top hose leaves the engine to go to the radiator. A bad thermostat can make your car overheat. If it has not been changed since 1992 it should have been changed long ago.
No
The answer depends on the thermostat setting as well as the kind of heating system that you have.
The radiator may be plugged up. There are products available to help clean the cooling system, and the cooling system should be backflushed after using them.
If your old thermostat is not working properly, you should consider replacing it with a new one to ensure proper functioning of your heating and cooling system.
I realize this is written for a Ford Taurus; however, the steps should be exactly the same:http://www.taurusclub.com/forum/index.php?showtopic=52556
Even though you have already replaced the thermostat, there are other issues that can cause your Nissan Maxima to overheat. Your fan may be stuck and not operating as it should.
Yes, a furnace thermostat typically requires a constant 24 volts for proper operation. This low voltage is supplied by a transformer connected to the heating system and is necessary for powering the thermostat and controlling the heating equipment. If the thermostat does not receive a steady 24 volts, it may malfunction, leading to heating issues. Regular checks of the power supply can help ensure the system functions correctly.
When setting up a Nest thermostat, use the RH wire if you have a heating system, and use the RC wire if you have a cooling system.
To connect the RH thermostat wire to the heating system, you should match the wire to the corresponding terminal on the heating system. Typically, the RH wire connects to the R terminal on the heating system. Make sure to turn off the power before making any connections to avoid electrical hazards.
YES!! And also change the thermostat while in there. i have to agree... its not real expensive when you already have the timing belt off... i got one for $60 (new)
If your fan clutch is working properly and your thermostat is good then it should not overheat.
