Q: How to remove and install Engine on Honda Civic?
A: It is therefore relatively laborious to undertake engine removal on these models especially for the independent mechanic. Because of its structural configuration the engine and transaxle must be withdrawn from the bottom as a single unit which is most effectively accomplished and safely done using a frame contact type vehicle lift. Start with placing the car on the hoist and the engaging the arms with the jacking points, pulling them up until they are touching the vehicle, but not the wheels. Open the fuel cap, depress the fuel pumpprime switch, remove the negative battery terminal and the fuel line. The outer and inner fenders splash shields; the engine and hood splash shields and the hood must be removed while the fenders and the cowl area must be blanked off. Empty the cooling and lubrication systems, then; uninstall the drives/belts, intake resonator, air filter housing, battery and battery tray. All vacuum lines should be clearly blanked off, the emissions hoses, the wiring harness connectors, and the fuel lines should be similarly disconnected and the parts marked with masking tape where necessary. Take out the PCM; unplug the positive cables and electrical connectors of the fuse/relay box; take off all ground straps as well as the other electrical connectors. Loosen the front wheel lug nuts, lift up the car and then take off the front wheels. Remove the heat shields, the brackets and pipes which attach to the exhaust manifold, take off the alternator and, also, disconnect the electrical connection close to the steering gear. Retain only the rear end of the exhaust system, remove any floor brace if fitted and disconnect the lower hose from the radiator. Lower the vehicle to remove the heater hoses at the firewall, upper morn radiator hose, cooling fan or fans, the shroud or shrouds and radiator. For manual transaxle models, the clutch release cylinder and hydraulic line are to be detached, while for automatic type, the shift control cable should be disconnected. Take out the front brace mounting bolts, get rid of the links in the stabilizer bar and ball joints in the lower control arms, then expel the drive axles as well as the downstream oxygen sensor connectors. Disconnect and unbolt the air conditioning compressor; this was done by unscrewing the bolts on the hoses, and then fastening it to a bracket. Place a lifting sling or chain to the engine to counterweight with the transaxle or be equal to it. Disconnect the through bolts of the front and rear engine/transaxle mount and then the mounts. Inspection for any connection before the removal of subframe mounting bolts as well as the removal of the subframe from the chassis and engine/transaxle assembly. Lower the assembly down so that no hoses or wiring are trapped and then use more blocks of wood or another jack to hold it up whilst removing the transaxle. Remove the lifting chain and reconnect it to the engine then bolt it to an engine stand. Installment is the reverse of the removal process, where attention should be given to worn out mounts and correct reconnection of the transaxle to the engine as well as subframe mounting bolt tightening, required fluids, battery reconnection and a road test to check proper running and mechanical fluid leaks.
