6. Turbo Test: The leakage of coolant would cause the engine to report high water temperature.

7. Various Pipe Fitting Test: smoke testing of brake hoses, power steering hoses, cooling system hoses, air conditioning system hoses, turbocharger hoses, fuel hoses, intake, and exhaust system hoses, etc.
