Antifreeze Tester Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9403
Jlab Export is a leading Antifreeze Tester Manufacturer,and suppliers in India
Engine coolant needs the right strength of antifreeze so that it neither freezes in winter nor boils over in summer. This tester checks permanent (ethylene glycol) antifreeze solutions and the boiling point of summer coolant. A quick test tells the mechanic whether the mix in a radiator needs more concentrate or more water.

Cooling System Practicals for Students
Students make up coolant samples of known strength from ethylene glycol and water, test each one and plot the readings against the mix. They see that freeze protection improves as glycol is added, up to a limit beyond which a stronger mix protects less. The boiling point rises with the glycol too. They then test coolant from a training engine such as the Diesel Engine Test Bed and work out the correction.
A full cooling system check also uses the Universal Radiator Pressure Tester to find leaks and test the radiator cap. Students learn that the cap pressure and the glycol both raise the boiling point. That is why a weak cap or a weak mix can each lead to boil-over.
Frequently Asked Questions
When should coolant be tested?
Test before winter and before the hot season, and after the system has been topped up with plain water, which weakens the mix. Take the sample only when the engine is cold. Never open the cap of a hot cooling system.
Does it work on propylene glycol coolant?
It is meant for permanent ethylene glycol coolant. Propylene glycol coolants give different readings at the same strength, so they need a tester scaled for them. Mixing the two types in one radiator also makes any reading hard to trust.
Why does antifreeze matter in summer as well?
Glycol raises the boiling point of the coolant as well as lowering its freezing point. A mix that is too weak can boil over in hot weather or under heavy load, even where frost is never a risk.
What do I do if the mix is too weak or too strong?
If it is weak, drain some coolant and add concentrate. If it is too strong, add clean water. A mix that is too strong also carries heat away less well. Run the engine to blend the coolant, let it cool and test again.
Does the tester show whether the coolant is worn out?
No. It shows the strength of the glycol mix. The corrosion inhibitors in coolant wear out with age even when the strength is right, so coolant is also changed at the interval the vehicle maker gives.
