Installation (Celica GTS)

Using Wrench (SST 09616-30011), hold oil pump pulley and tighten nut. Install timing pulley over crankshaft key. Install No. 2 idler pulley and ensure it moves smoothly. Tighten to specification. Install timing belt idler pulley and tension spring. Pry timing belt idler pulley eft as far as possible and temporarily tighten. Ensure there is no oil or water on idler pulley.
Temporarily install timing belt on a cold engine. If old timing belt was reused, align reference marks made during removal. Install timing belt on crankshaft, oil pump, water pump, and No. 2 idler pulley. Install timing belt guide with cup side facing outward.
Install No. 1 timing belt cover gasket and belt cover. Use Crankshaft Pulley Holder (SST 09213-14010), to hold crankshaft pulley. Install and tighten pulley bolt. Ensure crankshaft pulley groove aligns with "0" mark on No. 1 timing cover. If "0" mark is not aligned, turn crankshaft pulley and align its groove with "0" mark on No. 1 timing belt cover. Ensure No.1 cylinder is at TDC.
NOTE: Two types of camshafts are available: one with 2 holes on timing pulley contact surface and one with 5 holes on timing pulley contact surface. All replacement camshafts have 5 holes.
To align 2-hole type camshafts, use a wrench and turn camshafts so camshaft knock pin aligns with mark of No. 3 timing belt cover. See Fig 1. On 5-hole type camshafts, use a wrench and align camshaft knock pin and No. 1 bearing cap mark. See Fig 2.

NOTE: Two types of camshaft timing pulleys are available: one with 5 holes on the camshaft contact surface and one with one hole on the camshaft surface. All replacement pulleys have 5 holes.
Install timing belt on pulleys. If reusing old belt, align marks made during removal. Be sure "S" mark on timing pulley faces outward. Align timing pulley mark with No. 3 timing belt cover mark. Install timing pulleys with belt. On one-hole type camshafts, match camshaft knock pin with camshaft timing pulley hole. See Fig 3.

On 5-hole type camshafts, install knock pin into whichever camshaft timing pulley and camshaft holes are aligned. See Fig 4. If holes are not aligned, turn camshaft. Hold camshaft with wrench and tighten pulley bolts to specification. Loosen No. 1 idler pulley set bolt and stretch timing belt. Use care to not loosen set bolt further than point where idler returns.

Turn crankshaft pulley clockwise 2 revolutions from TDC to TDC. Tighten No. 1 idler pulley set bolt to 32 ft. lbs. (43 N.m). Ensure belt has tension between crankshaft timing pulley and camshaft timing pulley. Check valve timing.
Install No. 2 timing belt cover, spark plugs, and cylinder head covers. Install right engine mounting insulator and bracket. Tighten bolts to specification. Lower engine and install power steering pump drive belt, alternator bracket, alternator and drive belt. Adjust drive belt tension. To complete installation, reverse removal procedure.
