Why does my AC temperature go down? A clogged filter is often at the root of many performance issues. Blocked condenser: The condenser (the outdoor unit) of an AC needs to be clear on all sides so it can exhaust heat. If the condenser is blocked or excessively dirty, the air conditioner will not be able to cool down its refrigerant low enough. What does high evaporator Delta t mean in AC? High evaporator Delta T means that the incoming temperature and outgoing temperature is excessively large. It’s usually caused by low air flow across the coil, which includes problems...

Where is the coolant temperature sensor located in the engine? Where is the Coolant Temperature sensor located? Engine Coolant Temperature sensor is primarily located in the coolant passage of the liquid cooled engine; typically near the thermostat valve. The engine temperature sensor connects either to the temperature gauge or to the temperature indicator in the dashboard. Where is the outside air temperature sensor located? The outside air temperature sensor is normally mounted behind the grille or at the base of the windshield. Majority of these sensors work just the same as the engine air temperature sensor. However, some use an...
