The tester was created to eliminate suspected damage to the head gasket and the head itself in internal combustion vehicles with petrol, diesel and LPG engines cooled by liquid. If the gasket is leaking and CO2 is getting into the cooling system, the reaction fluid changes its colour to yellow or green.



The principle of operation of the instrument is based on measuring CO2 concentration - in case of increased concentration the reaction fluid reacts with CO2 and changes its colour.



 



The kit contains:

• 
  
  
• C2 reaction fluid 10ml (enough for 5 tests)
  
  
• Conical universal adapter 25mm-55mm
  
  
• Measuring tube
  
  

 



The black measuring adapter (25mm-55mm) gives the possibility to check 6 times more different coolant filler diameters than in testers with one white adapter. It allows to check among others cars, trucks, tractors, excavators, motorbikes, forklifts.



The adapter is made of a special rubber mixture resistant to high temperatures and appropriately soft - thanks to which it fits tightly to the filler and the tester's tube guaranteeing 100% tightness during the test.



 



Instructions for performing the test:



1.Fill the instrument with reaction fluid to the level between the chambers (approximately 2ml).



2.Connect the tester to the opening of the expansion tank or radiator.



3.Start the engine, put it into high revs to obtain higher combustion pressure.



4.Leave the engine at slightly increased rpm and observe the reaction fluid behaviour



5.A change in the colour of the reaction fluid to yellow or green within a few minutes of the test indicates a defective head gasket or damage to the head itself.



6.Carefully dismantle the instrument after testing is complete.



 



Test results:



1.Change in colour from blue to green in a diesel engine - indicates damage to the head gasket or the head itself.



2.Change of colour from blue to yellow in a petrol/LPG engine - indicates damage to the head gasket or to the head itself.



3.Reaction fluid colour blue - No CO2 detected in the system.



 



Safety information:

• 
  
  
• During the test on the radiator reservoir it is mandatory to take extra care when unscrewing the cap on a warm engine and during the test itself - risk of burns!
  
  
• Do not allow coolant to mix with reaction fluid during the test - the test may be invalid!
  
  
• Keep out of reach of children, wash hands thoroughly after the test!
