Works for peace of mind
I had been told by a mechanic that my Rolls Royce needed head gaskets at a cost of between £6000-£8000. I bought this and tested myself and it has proven the mechanic wrong and given me peace of mind. Well worth buying and checking yourself before spending loads of money!

You definitely need to reduce the coolant in your radiator or tank as it will suck up fluid once the car is started and the cooling system starts to flow if it is at normal to high levels. Test is very simple to run and gives very quick results.

المنتج أدواته ممتازه ولكن السائل غير فعّال ولا يؤدي الوظيفة المطلوبة و من الممكن أن السائل منتهي الصلاحية.

Block tester is Straight to the point, works great. Save me money time and guess work. My coolant kept rising during the test, so I let the steam in and fluid turned green. Suggest it’s a smaller gasket leak. So I’m removing the blocks to have them checked and resurfaced, and install a new gasket kit.
