The manufacturer recommends that the timing belt in the 1988 through 1991 2.5 Toyota Camry engines be replaced at 60,000 mile intervals after a study of the service record of this particular engine. This has been identified as a freewheeling engine, which means that in the event that the timing belt should come off, it is unlikely that the engine would experience any damage, but it is advised to do a compression test once the timing belt is replaced to ensure no damage has been done.
Tools Used: Set of 1/4-inch drive sockets, 1/4-inch drive ratchet, Set of 1/2-inch drive sockets, 1/2-inch drive air gun, Wheel puller set, Cotter pins, Set of metric wrenches, Floor jack, Jack stands
Change Timing Belt
Raise and support the car on jack stands. Using the appropriate sockets, remove the right front wheel and the fender apron seal. Remove the accessory drive belts and the power steering tank but leave hoses connected. Move the power steering tank out of the way. Remove the upper timing belt cover. Support the engine with the floor jack and remove the right engine mount and control rod. Remove the engine mount bracket.
Turn the crankshaft until the mark on the crankshaft pulley lines up with the O mark on the timing belt cover timing indicator. Make sure the camshaft sprockets have the mark on the sprocket straight up in line with the mark on the rear timing belt cover.
Remove the auto tensioner and the dust boot. Remove the crankshaft pulley bolt and the pulley. Remove the lower timing belt cover and the guide washer. Remove the timing belt.
Insert the auto tensioner in a vise and slowly compress the push rod into the body of the tensioner. Once the push rod is in to where the hole in the rod lines up with the holes in the body of the tensioner, insert a cotter pin to keep the rod from extending until it is installed.
Make sure the timing marks are aligned and if so, install the new belt starting on the right side and working clockwise, keeping the tension on the non-tensioned side.
Install the guide washer, the lower timing belt cover and the crankshaft pulley with the bolt. Torque the crankshaft bolt to 181-foot pounds of torque. Make sure the timing marks are still aligned. Install the dust boot on the tensioner and install the tensioner and tighten the bolts. Remove the cotter pin and let the tensioner apply tension to the timing belt.
Turn the crankshaft two turns and check the timing marks one more time. Install all the components in the reverse order of removal.
