Review on 🔍 UView 560000 Combustion Leak Tester: A Reliable Tool for Efficient Diagnosis by Jeremy Rodriguez

While I'm sure this product works with some leaks, I've seen this product not work on PZEV vehicles 3 times in a row. Just not enough smoke. I'm a Subaru technician and have used this on 3 cars so far that had obvious head gasket symptoms (and were fixed by replacing the gasket) but the fluid stayed blue during testing. I gave it 3 stars because it works on older home cars and other cars that aren't as eco-friendly as new cars, but the formula needs to be changed to detect PZEV head gasket failure.
