Note. Below are the procedures for checking for fluid and lubricant leaks.
1. Before starting the engine, check the levels of oil and engine fluids. If not enough, top up to the correct level.
2. Check for fuel leaks as follows:
- Turn the ignition switch to position "ON" (without starting the engine). After the fuel lines are pressurized, check for fuel leaks at the connections.
- Start the engine. Increasing the engine speed, again check for fuel leaks at the connections.
3. Let the engine run to check for increased noise and vibration.
Note. If the hydraulic pressure inside the chain tensioner drops after removal/installation, slack in the tensioner shoe can cause a rattling noise all the time and immediately after starting the engine. However, this does not indicate a malfunction. The noise will stop after the pressure is built up.
4. Warm up the engine thoroughly to ensure there are no fuel or engine fluid leaks (including engine oil and coolant).
5. Remove air by pumping from pipelines and hoses of hydraulic systems that have been disconnected (e.g. engine cooling systems).
6. After the engine has cooled down, check the engine oil/fluid levels again. If necessary, top up to the correct level.
Checking the oil groove of the intake camshaft sprocket
Attention.
- Perform this test only if the CONSULT-III detects DTC P0011 on self-diagnosis.
- To avoid scalding from escaping engine oil, check only when the engine is cold.
1. Check engine oil level.
2. Perform the following procedure to prevent the engine from starting unexpectedly during the test:
- Relieve fuel pressure (see chapter "Supply system").
- Remove intake manifold (see chapter "Intake and exhaust system").
- Disconnect the ignition coil and fuel injector connectors.
3. Remove the intake valve timing solenoid valve.
4. Turning the crankshaft of the engine with a starter, make sure that the engine oil flows out through the hole of the intake valve timing control solenoid valve (A). Stop rotating the crankshaft after checking.
1. Plug.
Note. The arrow in the figure shows the front of the engine.
Attention.
- Be careful not to touch rotating parts (drive belts, pulleys, etc.)
- Use rags to prevent splashing of oil on the person doing the work, on the outer surfaces of the engine and body surfaces. Be especially careful not to get oil on the rubber parts of drive belts, engine mounting pads, etc. If oil does get on the surface, remove it immediately.
5. If engine oil does not flow out of the intake valve timing solenoid valve hole in the cylinder head, perform the following checks:
- Remove and clean the oil filter.
- Clean the oil groove between the strainer and the intake valve timing solenoid valve.
6. Remove the components between the intake valve timing solenoid valve and the camshaft sprocket, and then check all oil grooves for blockages.
7. After checking, install the removed parts in reverse order.
