Why does my car take so long to get up to temperature?
The most likely scenario is that you only have a single malfunction: your thermostat. If it’s open all the time, the engine will take much longer to get up to temperature (as you’ve noticed), and some/most AC systems are completely paranoid when the engine isn’t at it’s operating temperature or isn’t cooling normally.
Why does the AC blow cold air when the car is moving?
My car has an automatic transmission. When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation. To maintain airflow when the car is in stop and go traffic, or is completely stopped, condenser fans will come on automatically.
Why does my car air conditioner spin when I turn it on?
Normally, the compressor can freewheel and spin, but when you press the button to activate the air conditioner inside your car, there’s an electromagnetic clutch that activates and causes the whole compression wheel to spin as a unit.
What happens to the coolant when the engine is too hot?
The rest of the hot coolant is regulated by the thermostat, which maintains a consistent engine temperature that does not rise above or fall below the engine’s normal operating temperature. If the engine is too hot, the thermostat will open to allow the flow of coolant into the radiator.
Why does my car’s temperature get high when I turn the AC on?
Dashboard gauges are not very accurate. If the needle goes a little higher than normal when you have the A/C on and as long as it stays within the normal range (i.e not in the red) then that is normal. Particularly if you have a smaller engine like a 4 cylinder, it has to work harder when the A/c is on.
When does the AC go cold in a Honda CRV?
1998 Honda CRV Replaced the AC compressor. AC is cold only when the engine is revving above certain rpm. When at a stop, the air is warm…but if I put it into neutral and rev the engine to, let’s say, 2000+ rpm, AC gets colder…or when Im driving, obviously.
Why does the AC blow warm air while idling?
During idling however, the AC starts blowing warm air and it gets warmer and warmer the longer the car is not in motion. It cools the car again when I drive. The system has been charged.
Can You Set Your air conditioner to whatever temperature you want?
We tend to think that we can set our air conditioning thermostats to whatever temperature we desire and have the air conditioner do its job no matter what.
