A very good quick test to help identify a combustion gas leak into the coolant system.
Very good kit. If you already have a coolant pressure tester kit with the quick release caps it fits them allowing you to connect this to more types of coolant reservoir tanks. Only issue is it comes with no instructions on what section to actually put the detection fluid in.

Supplied with bad test fluid
The hardware of the tester I have no issue with, it was as expected. The problem is with the supplied testing fluid. It should be blue but the fluid I received was already yellow making it impossible to perform an accurate test. A bit disappointing to receive with bad fluid and there seems to be no easy way to get in contact with the seller (EURAKOP-UK) directly to arrange for the replacement test fluid to be sent out. If EURAKOP-UK read this review I urge you to reach out and rectify this issue.

Pas de notice d'utilisation; Efficace; M'a permi de confirmer mon probleme de joint de culasse; Ne détecte pas (bien sûr) un probleme d'etancheité huile/Liquide refroidissement, seulement Etancheité LdR/chambre de combustion; Il faut bien le savoir.

Like it and tested my car on spot to decide the next action

Worked very well, thanks to its system, you can prevent liquid entering the upper part, so you don't need to remove any coolant from the system before the test, or at least that is what I believe.
