Changing the timing belt on a Honda CRV isn’t a straightforward job; it is rather more troublesome than remove the opposite drivebelts. The primary problem lies in attending to the belt itself, as there are a number of different components you may must disconnect. If doable, altering the timing belt is a activity finest left to knowledgeable auto professional.
Accessing the Honda CRV Timing Belt
Unplug the battery’s negative (black) cable. Apply the parking brake and block the rear wheels. Increase the front finish of the automobile on jack stands and take away the left (driver’s facet) wheel. Remove the splash protect under the engine by disconnecting its fasteners.
Remove the drivebelts by loosening the tensioners (rotate the tensioner bolt clockwise with a socket wrench). Unbolt and take away the facility steering pump with out disconnecting its hoses. Disconnect and take away the alternator and the valve cowl.
Assist the engine with a ground jack, putting a wooden block on the jack to forestall damaging the pan. Remove the engine mount bracket on the higher left aspect Place the engine’s primary piston at its prime down middle place as described in Part 2.
Disconnect the camshaft place sensor and the facet engine mount bracket so you may take away the higher timing belt cowl. Loosen the crankshaft pulley bolt with a socket and breaker bar, and take away the pulley from the crankshaft to take away the lower belt cowl. Remove the crankshaft place sensor.
Remove the spark plugs from the engine. Remove every ignition coil by disconnecting its electrical connector and remove its mounting nut. Use a ratchet with a spark plug socket to take away the plugs from the engine. Install a compression gauge into cylinder primary’s spark plug gap. Disable the gas system. Remove the gasoline cap, take away the engine cowl and loosen the pulsation damper by a full flip.
Connect a ratchet or breaker bar and socket to the bolt on the crankshaft. Flip the crankshaft till compression registers on the gauge. Slowly flip the crankshaft once more till the highest down middle notch aligns with the pointer on the timing belt cowl.
Changing the Honda CRV Timing Belt
Loosen the timing belt’s tensioner bolt on the middle pulley with the socket and breaker bar. Push on the tensioner to launch the strain and slip the belt off the pulleys. Be sure the sprockets are in the correct place. Align the camshaft sprocket so the half with the phrase “up” is on the 12 o’clock place. Quickly put the crankshaft pulley and bolt again on to show the crankshaft till its sprocket’s timing mark aligns with the pointer on the oil pump.
Install the brand new belt across the crankshaft sprocket first, adopted by the tensioner pulley, the water pump pulley and the camshaft sprocket. Loosen the tensioner’s mounting bolt with a one hundred eighty-diploma flip so the tensioner can barely pressure the belt. Flip the crankshaft counterclockwise two full occasions and test its timing marks and the camshaft sprocket’s index marks to ensure every thing is aligned. Insert a zero.12-inch diameter pin into into the tensioner pulley’s holes and tighten the mounting bolt to 33 foot-kilos.
Remove the pin from the pulley and set up all the opposite elements within the reverse order of removing. Alter the drivebelts as vital, tighten the gas pulsation damper with new sealing washers and reconnect the battery.
