The refrigerant gas used in a vehicle’s A/C system is dependent on the model of the car and/or the manufacture year. To check which refrigerant gas your vehicle uses, locate the manufactures identification sticker under your bonnet.
To find the low-side port, first locate the A/C compressor. Two metal tubes come out of the compressor. The smaller tube is a high pressure line that runs to the front towards the radiator. The larger diameter tube which runs back towards the passenger compartment is the low pressure line. Follow this until you find the port. Some service port caps are marked with a “L” and “H” to distinguish between the high and low ports.
Readings between 45°-60°F indicate a properly charged system.
STP® Air-Con Cleaner cleans and deodorizes automotive air conditioning systems, including the vents, ducts, evaporator core, and drain pan. It effectively eliminates odours caused by microbes while providing a clean, fresh scent.
YES! The STP® Air-Con range allows you to properly maintain and service A/C systems without the need for expensive equipment and training. This 10- minute A/C recharge job is as simple as the rest of your car maintenance: checking oil, tyre pressures and topping up screen wash.
You need to wear gloves for a couple of reasons:
1) As you release refrigerant from the can into your vehicle’s A/C system, the can will become very cold to the touch
2) You are working around a running vehicle. There will be hot surfaces that could possibly burn you. In order to protect your hands from the cold can and possible burns, always wear cloth-lined gloves as well as safety eyewear.
Refrigerant does not break down, expire or get used up. If the A/C system is low on refrigerant, it’s because there is a leak! If your car is more than five years old, then chances are that the O-rings and gaskets have become brittle and inelastic causing small leaks throughout the system. STP® Auto Freeze, EZ Chill or Advanced R-1234yf Auto Air Con Recharge can help top up lost refrigerant and restore cold air. Check which refrigerant gas your vehicle uses by locating the manufactures identification sticker under your bonnet.
Yes, not only is overcharging your system potentially dangerous, an overcharged system will not function properly and can seriously damage your A/C compressor or other components. The symptom of an overcharged A/C system is exactly the same as a system that is undercharged: warm air coming out of the vents. In order to prevent overcharging, it is important that you measure the A/C system pressure before charging and follow the respective instructions as per the reading. If your A/C system is overcharged, seek professional assistance to have the excess refrigerant recovered from the A/C System.

STP® Auto Freeze and STP® EZ Chill are R-134a refrigerants, specially formulated with an advanced additives package to help top up lost refrigerant and restore cold air to an automotive air conditioning system. The patented ICE 32® additives package contains active chemistry to help remove deposit build up on the interiors of A/C system pipes and tubes, therefore increasing the cooling efficiency. The specially designed formula also includes leak sealers and O-ring conditioners to help minimise refrigerant loss and prolong A/C system performance. Using STP® Auto Freeze and STP® EZ Chill Air-con Recharge is easy. This 10-minute recharge job is as simple as the rest of your car maintenance: checking engine oil, the tyre pressure, replacing screen wash.
STP® R-1234yf Advanced Auto Air-Con Recharge is a R-1234yf refrigerant, specially formulated with an advanced additives package to help top up lost refrigerant and restore cold air to an automotive air conditioning system. The specially designed formula contains premium compressor lubricant to reduce friction on seals and metal components which help extend the vehicle’s A/C system life. It also includes UV dye to detect leaks in metal & rubber components, helping identify areas where refrigerant is escaping from the system. Using STP® R-1234yf Advanced Auto Air-Con Recharge is easy. This 10-minute recharge job is a simple as the rest of your car maintenance: checking engine oil, the tyre pressure, replacing screen wash.
Yes. The dye will not affect A/C performance.
Check your A/C system pressure using a STP® Reusable Trigger & Gauge or STP® R-1234yf Gauge & Hose and determine whether a top up of refrigerant is required. If the pressure reading indicates the A/C system is low on refrigerant, it is possible that there is a small leak. This will allow the system to blow cold, but just not as cold as it has before. Topping up the system with additional refrigerant will help restore cold air in this instance. If the A/C system pressure is correct, adding additional refrigerant will not make the system blow out colder air. On the contrary, it will overcharge the A/C system and result in warmer air blowing from the vents.
In 2020, we are launching a hybrid and EV vehicle compatible formula for STP® Auto Freeze and STP® EZ Chill Air-Con Recharge. Check the front of the label on either product to confirm whether your canister contains the Hybrid & EV vehicle compatible formula.
No, currently STP® R-1234yf Advanced Auto Air-Con Recharge is not hybrid or EV compatible.
Automotive A/C systems are closed systems that are subject to harsh weather and road conditions. Your A/C has plenty of places for leaks to occur – in metal components like the condenser, evaporator, accumulator or receiver/drier; as well as in the rubber components like hoses, O-rings and gaskets. The refrigerant in your vehicle’s system only gets lower because the system has developed a leak, which over time, causes you to feel warmer air blowing from the vents. Typically, refrigerant leaks occur in cars that are over five years old because the rubber O-rings and gaskets that seal the different components of the system have become brittle and dried out, allowing the refrigerant in the system to leak past. Using STP® Reusable Trigger & Gauge or STP® R-1234yf Gauge & Hose allows you to measure the A/C system pressure to determine whether refrigerant has leaked from the system.
While in the air conditioning system, STP® Super Seal remains a liquid lubricant and contains additives to penetrate and rejuvenate O-rings, gaskets, and other rubber connectors to prevent leakage. The chemical formula also includes a drying agent that eliminates any moisture that may occur inside the air conditioner. In metal components, refrigerant leaves the system through the leak and chills the outside air, resulting in condensation. This moisture activates STP® Super Seal fluid to form a scab on the exterior of the metal component and patch up the leaking area.
STP® Super Seal is designed for use in R-134a A/C systems. It is not compatible with vehicles that have R-12 or R-1234yf systems.
One can of STP® Super Seal is all you need to seal pinhole-sized leaks in your system. If the system is leaking slowly and holds a charge for more than two weeks, STP® Super Seal should seal the leak(s). However, if your A/C system cannot hold a charge for 24 hours, this may indicate an abnormal/large leak. Seek assistance from a qualified technician in this situation.
A canister of STP® Super Seal contains enough fluid to seal multiple pin-sized holes in both metal and rubber components in a single application. However, if your A/C system cannot hold a charge for two weeks, there may be an abnormal/large leak. Seek assistance from a qualified technician in this situation.
STP® Super Seal will take effect within one day of installation.
It depends on the nature of the leak but any leak fixed by STP® Super Seal during a recharge will create a permanent bond that will last approximately 12 months of A/C usage. In addition, STP® Super Seal will continue to flow through the A/C system as a lubricant and seal any new leaks that may develop, which makes it great for preventative maintenance.
In this case, seek help from a qualified technician.
One can of STP® Super Seal is all you need to seal pinhole-sized leaks in your system. In order to determine the size of your leak, use the following rule of thumb: If your car can hold a refrigerant charge for two weeks before blowing warm again, then STP® Super Seal will be able to patch your leak. If your vehicle is losing refrigerant in less than two weeks, then you may have an abnormal leak and using two cans of STP® Super Seal will not help. In this case, you should seek help from a qualified mechanic.
No. The chemical formulation remains in a liquid state inside the A/C system until it detects moisture at the leak point and self-seals. STP® Super Seal contains a drying agent to prevent any sealing activity while in the system.
1. Start engine and set A/C to maximum cooling with system on re-circulate. Allow to run for 2 minutes, ensuring the air conditioner’s compressor is running and clutch is engaging.
2. Turn air conditioner & engine off.
3. Turn the valve handle of the recharge hose counter clockwise until the piercing stem is in the up-right position. This will prevent the accidental piercing of the STP® Super Seal can. Caution: do not add STP® Super Seal through a manifold gauge & hose set. Use only enclosed recharge hose.
4. Carefully screw the top of the STP® Super Seal can onto the end of the recharge hose with the valve hand.
5. Locate the low side service port and remove the protective dust cap. The low side port is located on the larger diameter aluminium tubing, between the evaporator and compressor.
6. With the A/C switched off and whilst wearing goggles and gloves, pull back the sleeve and attach the hose by pressing the coupler down onto the low side port. Make sure fitting is tight. NB: the coupler will only fit low side port ??” do not force.
7. Holding the can up-right, turn the valve handle on the recharge hose clockwise until the piercing stem has punctured the canister. 8. Turn the valve handle counter clockwise, until you hear the refrigerant moving from the car A/C system into the STP® Super Seal can.
9. Wait 10 seconds and turn valve handle clockwise to close valve. 10. Do not remove the can, but shake the canister to allow refrigerant to mix with STP® Super Seal.
11. Start engine and set A/C to maximum cooling with system on re-circulate.
12. Holding the can in an upside-down position above the service port, turn the valve counter clockwise. Shake lightly until can is empty.
13. Disconnect the recharge hose from the low-side service port.
14. Ensuring there is no residue in the can, disconnect the can from the recharge hose and discard. Turn the valve handle on the recharge hose until the piercing stem is in the up position.
15. To prevent STP® Super Seal from sealing the service port, immediately flush the charging port with STP® EZ Chill or STP® Auto Freeze recharge product.
16. Allow the A/C system to run for 15 minutes to let the STP® Super Seal and refrigerant circulate.
