Automotive workshop business - A new concept of car air conditioning services without removing parts & turning it into a profit center









We change our engine oil frequently to avoid expensive overhaul. 

In our car air conditioning, there is a compressor oil that works to lubricate the compressor to prevent it from overheating. 


90% of car AC problem is caused by this compressor oil not change regularly. It is extremely cumbersome & difficult to remove this compressor oil using traditional ways.

With our KoolTec AC Concept, full compressor oil replacement service job can be done in just an hour.  

And what if you can answer & provide a "8 items" report to your customer in just 20 mins for an assessment of his car's air conditioning problems ?

Can you see opportunities ?

90% Of Cars' Air Conditioning Failures Are Caused By Compressor Oil Not Changed Regularly




In the good old days, we frequently see automobiles having to go through overhaul of engine.  The lubricant companies began to educate workshops & car owners to replace engine oil at recommended service intervals.  Now, we hardly see our car going through the cumbersome engine overhaul piece of work.  We diligently replace our engine oil at 5000km or 10,000km. 

                              AWARENESS = ACTION = HEALTHY CAR ENGINE

The primary purpose of lubricants in general are (1) Lubricate to reduce friction (2) Remove frictional heat (3) To absorb dirt.  Over time, it would loose its viscosity, its ability to lubricate & it would turn acidic.  There are now specific service intervals for engine oil, ATF, manual gear oil, differential axial oil, brake fluid, power steering fluid & radiator coolant.  

Replace compressor oil (PAG) every 20,000 km

The service interval for replacement of compressor lubricant is between 20,000 km to 30,000 km depending on the driving condition.  The modern car ac system uses PAG( Poly-Alckylene-Glycol ), which is synthetic, compressor oil & refrigerant R134a.  The PAG oil mixes 100% with the R134a & it flows through the entire system lubricating the compressor.  The amount of PAG oil & R134a a car ac system needs is specified by the car manufacturer & it differs from manufacturers.  

PAG oil - correct amount to use 

Unlike engine oil, where we use a large amount to lubricate(in the range of 4 liters) , the PAG oil used is usually in the range of 70ml to 200ml.  This makes the PAG oil quantity or amount very critical to obtain a cold temperature. Here’s a way to picture this.  If your car engine needs 4L of oil, if we add in an extra 2L or drain out 2L of oil.  This would adversely affect the performance & protection of the engine & eventually lead to serious damages. Too much PAG oil or too little of it would similarly affect the performance of the compressor & its lifespan.

PAG oil replacement - A pain in the ass!

Traditionally, it is a very difficult & time consuming task to remove the compressor oil.  The compressor, condenser, evaporator & expansion valve must be removed & flushed separately.  And the dash board must be removed to get to the evaporator & expansion valve.  Now there is a Cool & Simple Way to Make your car AC Cold” - KoolTecThe AC compressor oil can be removed & replaced with new oil in just 1 hour & no parts are removed in the process.  Check out your nearest KoolTec service centres for a free diagnostic check.

Replace your car’s ac compressor oil every 20,000 km to enjoy a cool & fresh cabin & avoid expensive repair cost!
