π§ A Simple Test That Can Reveal a Big Problem! ππ¨
Ever wondered how we can check for a possible head gasket failure without taking the engine apart? π€
Here's a quick demonstration of one of the tests we use in the workshop!
Using a combustion leak tester, we draw gases from the cooling system through a special testing fluid.
π§ͺ If combustion gases are present, the fluid changes colour, giving us an indication that gases from the engine's combustion chambers may be entering the cooling system.
A positive result can point towards a failed head gasket, cracked cylinder head or another internal engine issue.
It's a relatively quick and simple test that can provide some really useful information when diagnosing coolant loss, overheating or excessive cooling system pressure.
Of course, no single test tells the whole story, but it's a great place to start! π§
