yes
A refrigerant (freon) is required for an A/C system to cool. Therefore, no, the A/C should not work is the freon is removed.
compressor maybe sticking which doesn't filter freon through the system
Connect a freon gauge and freon tank to the low side ac port. With the engine running and ac on high, open the freon tank to fill the system to the full line on the gauge.
No. Dex-cool is an engine coolant. Freon (134r) is a gas used in the automotive AC system.
Yes your ac just won't be cold
Assuming it is the same type of "freon", yes. The freon would be removed from the old system with a recovory/recycling machine.Assuming it is the same type of "freon", yes. The freon would be removed from the old system with a recovory/recycling machine.
No, Freon is no longer used in vehicles' cooling system. Should you take your car in for maintenance, the mechanic will use a special vacuum to remove and properly dispose of the Freon. The mechanic will then use R-134, a replacement for Freon.
The freon has to be removed and the pressure released from the ac system. Then the valve can be removed and replaced. The system will need to have a vacuum pulled and freon put in again.
2-5lbs
Freon is added in the low pressure port of the ac system. It is under the hood close to the ac drier.
Connect a freon gauge and the freon can to the low side ac port. With the ac running on high and the engine running, open the freon. Let it flow until the gauge shows that the system is full.
