This is part 2 for the repair " How to replace the timing belt on 1993-1997 Geo Prizm " if you landed in this page while browsing the web and you would like to see this job from the start click here.   Otherwise continue reading.

Remember: the vehicle we are working on is a 1995 Geo Prizm equipped with a 1.6L engine  4A-FE, since this is a Toyota engine, the same engine is found on 1993-1997 Toyota Corolla.

    

    

   

    

    

    

    

    

    



    

    

    

    

    

  

 

 

  

  Remove the crankshaft center bolt, make sure that the crankshaft doesn't turn to keep it on TDC.
















 Next, using a harmonic balancer puller remove the harmonic balancer from the engine and set it aside.














 Remove the remaining timing belt covers and timing belt guide washer.


















 Notice the TDC alignment marks on the lower timing belt sprocket.














 Loosen the timing belt tensioner bolt, push the tensioner away from the belt to release its tension and lightly tighten the bolt.









 In order to get the timing belt out, it is necessary to separate the front engine mount from the mounting bracket, support the engine with a floor jack while doing this to avoid the engine from dropping too low and breaking any parts, make sure that you place a wooden block in between the floor jack and the oil pan to avoid damaging it.

Remove the upper bolt as shown in the image and the lower nuts.











 Remove the bolt that fastens the AC hose to the front engine mount to gain access to the engine mount retaining bolts.















 Loosen the front mount retaining bolts, tilt the engine mount and slide the timing belt out of the engine. Remove the timing belt tensioner.

 

 

 

 

 

 

  Install the spring on the new timing belt tensioner provided with the timing component kit, install the tensioner on the engine, push the tensioner away from the spring to provide room to install the timing belt, slightly tighten the tensioner bolt, slide the new timing belt between the engine mount and the mount bracket, install the bolts back on and tighten them up, remove the floor jack from under the engine.

 






 Install the timing belt in a counterclockwise motion startting from the crankshaft sprocket, make sure that both TDC marks on crankshaft and camshaft sprockets are aligned, loosen the timing belt tensioner bolt to allow the tensioner to operate, turn the engine clockwise 2 turns until the no. 1 piston is in TDC of compression stroke, ensure that the timing marks are aligned and that the belt tensioner is operating, tighten the timing belt tensioner bolt to 27 ft-lbs. 

Press the timing belt with a force of 4.4 lbs, belt should deflect 0.20 - 0.24 ins.




 Remember: NO. 1 cylinder is in TDC compression stroke only if the orifice on the camshaft sprocket shown in the image is aligned with the mark on the camshaft bearing cap.

Install all the components in the reverse order you took them off except for the valve cover, torque the harmonic balancer pulley bolt to 87 ft. lbs.
We will show you how to replace the valve cover gasket and seals prior to installing the valve cover back on the engine in the following steps.










 Bend the retaining tabs away from the seals, turn the valve cover around and using a punch drive the old seals out .

 

 

 

 

 

 Using a socket of near the same diameter of the seals, drive the new seals into the valve cover as shown in the image, once the seals are installed apply a light coat to the inside edge of the seals to allow them to slide over the spark plug metal tubes without tearing them.










 Remove the old valve cover gasket, clean the surface of the valve cover where the gasket is mounted with a towel and brake cleaner to remove any oil and dirt that may be trapped inside, once is clean install the new valve cover gasket.











 Apply a light coat of silicone to the edges of the camshaft bearing caps as shown in the image to ensure propper seal between the valve cover and the cylinder head, install the valve cover, new washers and retaining nuts, slide the wiring harness over and fasten it to the valve cover with the two bolts you removed earlier, install the PCV valve hose and the vacuum hose, install the spark plug wires back in place, connect the negative battery cable back on and start the car.

If you did everything correctly the car should run as good as new without any problems.
