- Road test the vehicle if running to confirm the customers complaint. Install data scanner and engine analyzer. Run full diagnostic tests on the fuel, ignition, and computer control systems. The engine spins very fast indicating there is no compression being produced. Perform all necessary pin point tests checking the wiring, grounds, relays, and related circuit components to isolate the problem to a valve timing issue, most likely a timing chain component problem. The camshafts are not rotating which means a major mechanical problem has occurred and with this being an interference style engine, it is recommended that the engine be replaced due to the extent of repairing the existing assembly.
- Drain engine coolant and flush system in both directions with water to remove sediment. Hook flush equipment to the vehicles cooling system and forward and reverse flush radiator, heater core, heater control valve, and engine block. Remove the vehicles overflow container and wash out debris. Reinstall overflow and top off to capacity. Run engine on the flush equipment until the engine coolant is clean and the acidity is at an acceptable level. Top off cooling system to capacity with specified amount and type of new engine coolant. Run engine to circulate coolant and check freeze point and acidity to insure a proper mixture is in the system. Run engine to operating temperature and purge air from system. Check to verify that the electric cooling fans are operating within their specified temperature range. Check system for leaks and road test. NOTE: If the system develops an air pocket, the coolant level may decrease slightly. If this occurs, the customer should return to have the system topped off.
- Install refrigerant recycling equipment on the system and remove any remaining system pressure and oil. Clean all exterior connections requiring servicing to remove debris. Vacuum system for 30 minutes to remove any moisture. Fill system to capacity with new esther oil, dye, and refrigerant. Clean condenser fins and inlet and outlet air passages. Run engine to operating temperature and monitor system pressures. Check the operation of the condenser fan, blend door, and check and verify vent temperatures. Check for leaks using dye detection light and insure that all system components are dry. No leaks are present at this time. If the system performance decreases, the customer should return for additional leak testing.
- (See cooling system and air conditioning services) Remove all necessary brackets, vacuum lines, wiring harnesses, air conditioning compressor, alternator, power steering components, starter, water pump, and hardware to gain access to the engine assembly. Drain all fluids from the existing engine assembly. Remove the radiator and hood assemblies to gain clearance for the engine removal. Remove the engine mount hardware and support the transmission and remove the bell housing hardware. Remove the engine assembly from the vehicle and remove the accessories and all brackets from existing engine. Install the replacement engine into the vehicle onto the existing engine mounts and install all components previously removed into their correct locations. Fill engine with correct level and type of coolant and engine oil. Run engine to operating temperature and check for leaks. Adjust vehicles ignition timing and idle speed (if applicable) and road test to verify correct operation. Run the engine to operating temperature and run a full diagnostic on the computer controlled components to insure that all of the vehicles systems are working within parameters.
