Q: How can the engine and transaxle be removed and reinstalled as a single unit on an 1995 Acura Integra?
A: You must take the entire engine and transmission assembly off as one piece to complete the work. Start with three steps: allow air into the fuel system, disconnect the negative cable from the battery, and get your radio activation code for vehicles with anti-theft systems. Separate the positive cable, and take off the ends from all other cables. First save the front parts of the car, then lift off the hood. To open up the engine area of an lntegra, you need to remove the engine compartment strut brace, air cleaner, and the air intake duct all at once. Mark your tools as you take them off, using tape labels and sketches to show how everything connects back together later. Turn off all the electrical connection wires, pull out the main wiring, unravel all fuel and vacuum tubes, and cut the ground connection. Start by draining your car's cooling system and pick up the reservoir tank, fan shroud, cooling fan, and whole radiator. Take out all drive belts, move the idler, disconnect the accelerator controls, and cruise control wire, then unscrew the power steering pump while keeping the hoses hooked. Also, loosen the air conditioner compressor but don't remove the tubes. Carefully take the alternator and frame loose, lift your vehicle, block it securely, remove the splasher, drain engine oil, and replace the filter. If your car uses an automatic transmission, remove these three things: throttle control cable, shift cable, and coolant lines connecting to the transmission. Pull off the crank crankshaft pulley, cut loose the exhaust system, stand the transaxle with a jack, and hang an engine lift from hooks on the engine. Keep yourself safe while working with the engine by moving the hoist into place, tightening the sling till there's no slack left, and don't put yourself under the engine at any time. Take off the driveaxles first, then loosen the clutch release cylinder nut for manual transaxle cars, slide the transaxle shift linkage off, and remove the bolts that attach the engine to its brackets. Rerun the checks to see if anything's still connected, lift up the motor a bit to let the mounts slide off, then carefully lift the whole engine/transmission piece out of the engine bay without anything sticking. Place wood blocks beneath the engine-transaxle assembly, lift it down to the floor, take out the clutch and flywheel or driveplate, and mount the engine on a support stand before disconnecting the transaxle. If any of the mounts between the engine and transaxle are worn or damaged, you'll need new ones. For cars with manual transmission, put the clutch and pressure plate on correctly, applying special high-temperature grease to the inner shaft of the clutch. Join engine and transaxle by fitting them together, without relying on bolts to make them stick, and when working on automatic transmission cars, set the torque converter slowly and carefully. First, place the engine mounts correctly with the frame. Now, place bolts, fasten them tight, and use the engine/transaxle assembly to pull down into the engine area. The rest of the assembly process goes backward following the steps for removal. Pour coolant, oil, power steering, and transmission fluid into the right places, start the engine to find out where any leaks are, make sure all features work properly, put the hood back on, and test drive the car. If your car's air conditioning system released gas, send it to a professional who can safely remove and refill the system.
