02-7 1116-01 Engine and accessories ▶ Engine has a lot of precise components. The specified tightening torque and correct procedures should be kept during service works. And, the working area is always clean and well prepared. When disassembling the engine, related parts (bolts, gaskets, etc.) should be stored as a set. Carefully read the disassembly and reassembly procedures in this manual before starting the works. Clean the components completely with engine oil before assembling if needed. Fully drain the engine oil, coolant and fuel from the vehicle and seal the inlets with the plugs before removing the engine. All the interference should be eliminated before removing the engine. - - - - Tightening the fastener ▶ When reassembling the parts to G20DF, use the angle tightening as a final step. 1. Clean the mating surfaces before tightening. 2. Place the marks with paint to tighten by angle if the angle wrench is not available. Exhaust system ▶ Wear the protective gloves before removing the exhaust pipe. The exhaust pipe is very hot immediately after stopping th engine. Check if the exhaust pipe is fully cooled down before servicing the exhaust system. - - Cooling system ▶ Scalding hot coolant and steam could be blown out under pressure, which could cause serious injury. Never remove the coolant reservoir cap when the engine and the radiator are hot. - The position and direction of the componets is based on the rear view. Do not tighten the fasteners with excessive force. Especially, the threads of cylinder block could be damaged. The self screw bolt makes the thread itself when tightening it. Do not apply excessive force. Do not reuse the bolt that has been tightened with angle tightening method. |
