CAUTION: ¼ Always replace exhaust gaskets with new ones when reassembling. ¼ With engine running, check all tube connections for exhaust gas leaks, and entire system for unusual noises. ¼ Check to ensure that mounting brackets and mounting insulators are installed properly and free from undue stress. Improper installation could result in excessive noise or vibration. ¼ Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one. ¼ Before installing a new oxygen sensor, clean exhaust system threads using oxygen sensor thread cleaner tool and apply anti-seize lubricant. ¼ Do not overtorque the oxygen sensor. Doing so may cause damage to the oxygen sensor, resulting in the MI coming on. ¼ Be sure to use genuine exhaust system parts which are designed especially for heat resistance, corrosion resistance, and shape. ¼ Perform the operation with the exhaust system fully cooled down because the system will be heated just after the engine stops. ¼ Be careful not to cut your hand on the insulator edge.

After the repair, bleed air from the piping by pumping the priming pump up and down until it becomes heavy. To start the engine, rotate the starter for a maximum of 30 seconds. To start the engine more quickly, crank the engine while pumping the priming pump (requires two workers). If the engine does not start after rotating the starter for a maximum of 30 seconds, stop it once, and pump the priming pump again until it becomes heavy. Rotate the starter again until the engine starts running. After the engine starts, let it idle for at least 1 minute to stabilize the behavior. When air is bled completely, the pumping of the priming pump suddenly becomes heavy. Stop the operation at that time. If it is difficult to bleed air by the pumping of the priming pump (the pumping of the priming pump does not become heavy), disconnect the fuel supply hose between the fuel filter and the injection pump. Then, perform the operation described above, and make sure that fuel comes out. (Use a pan, etc. so as not to spill fuel. Do not let fuel get on engine and other parts.) After that, connect the hose, then bleed air again. Start engine and let it idle for at least 1 minute after performing air bleeding.
Checking Priming Pump
NLFE0024
Before checking priming pump, make sure that fuel filter is filled with fuel. 1. Disconnect fuel supply hose. Place a suitable container beneath hose end. 2. Pump priming pump and check that the fuel overflows from the hose end. If not, replace priming pump.
