Cooling System
For cooling system maintenance, you need measuring tools like a refractometer or antifreeze tester. Filling and bleeding sets prevent air in the circuit. When ordering, check the connection size and the OEM number you replace. That ensures the adapter fits your vehicle. Use these tools for the correct fluid ratio and a smoothly running engine.

Cooling System Testers and Filling Equipment
Which size or version do you need?
To test antifreeze, use a refractometer or an antifreeze tester. These measure the freezing point and concentration of the fluid. Check beforehand whether the tester suits the type of coolant you use. Some testers only work with ethylene glycol, others also with propylene glycol.
Where ordering goes wrong
Adapters and filling equipment must fit the vehicle's cooling system. Always check the OEM number of the original part. A wrong adapter leaks or does not fit. Also measure the diameter of the filler neck. This prevents you from returning a set.
Why a bleeding set matters
Air in the cooling system causes overheating and a poorly working heater. With a bleeding set, you fill the system under vacuum and draw the fluid straight in. This saves time and prevents air pockets. Afterwards, use a tester to check the ratio. This keeps the engine at the right temperature.
