OE Viscosity Synthetic PAG Oil 46 for mobile A/C systems. For use w/ R-134A only.
The receiver drier stores excess refrigerant filters out any contaminants that may be in the system and removes moisture from the liquid refrigerant to protect the system from internal corrosion.
Under normal operating conditions, the drier canister should be warm to the touch. The presence of frost on the canister indicates an internal restriction.
The receiver drier should be replaced anytime the a/c system is opened and never leave the fittings uncapped prior to installation. When performing any service on the HVAC, always make the receiver drier the last component replaced.
Fast-evaporating product designed to assist in the removal of debris, oils & moisture from A/C systems. It is an environmentally-desirable product as it contains no chlorinated solvents or ozone-depleting compounds (ODCs). Contains no ingredients that will cause corrosion of metal surfaces.

Typically, a good working system will have cooling vent temperatures 2-30 degrees lower than ambient.
Get to know what the sound and feel of your AC is like when blowing on maximum. If the temperature is low, but the airflow is slow when set on maximum, it could be that your Cabin air filter is blocked. Locate and replace.
Whenever a system stops working and the compressor has "locked up," it is very likely that particles of metal have been distributed throughout the system.
This dirty oil and powder must be removed from the system entirely before replacing parts.
If the vehicle is fitted with a micro-bore parallel flow condenser, it must be removed. Similarly, the receiver drier or the accumulator drier should be removed.
The system can then be flushed with the vehicle manufacturer's recommended flushing medium. The use of non-compatible flushing solvents may damage the system seals, and residues may interact with the system lubricant.
It is best to use a specially designed flushing machine with a selection of fittings to attach the forward and reverse pipes. The system sections should be flushed in the reverse direction to normal flow.
Solvent-based flushes should be removed by evacuating the system at a minimum of 29.9 in Hg for at least 45 minutes. Oil-based flushes cannot be complexly removed; therefore, the flush must be compatible with the refrigerant oil that will be used in the system.
A new condenser and drier should be used to replace the ones removed as they cannot be adequately cleaned. Faulty system parts should then be replaced. New seals used where old seals have been disturbed.
Did you know that Most clutches fail due to low voltage which causes them to slip and create extreme heat?
If the clutch face is discolored that is possibly the case. You may also see some epoxy from the coil windings that may be there as well. To see if this is the problem, start the vehicle and turn all of the accessories on. With a voltmeter check the voltage to the clutch and make sure it's to the manufacture's specifications. If the voltage is all right then there is a problem with high head pressure.
This kit protects a Compressor Clutch from failure due to low or varying voltage. If voltage drops below 12V, the relay picks up charging voltage from + starter post. Will not protect due to a charging problem.

The expansion valve is a refrigerant metering device that creates a temperature/pressure drop.
It also divides the system into two zones, high pressure and low pressure. The most common block valve failure is a loss of gas charge inside the power element head. Plugged up expansion valves cannot be flushed out and must be replaced.
When replacing a capillary type expansion valve make sure the capillary coil or bulb is properly attached to the outlet side of the evaporator line and well insulated with prestite insulation tape.
