Question about 2003 Ford Focus
Can someone HELP ME!!! the timing belt on my 2003 ford focus 1.8 lt went on me I've got the replacment belt but because the timing belt failed I know know what position the crankshaft and cams need to be in before I install the new belt I can't find any indication marks on the crankshaft pulley or on the cam gears what would be helpful is if anyone could give me a step by step detailed instruction about how to install the new belt pics included if you want to. My email address is firstname.lastname@example.org so if anyone can please help me int would be really grateful thanks guys
Kind regards David Boghossian
Firstly if the belt went you probably have bent valves. However if you want to assemble and see remove cam belt covers,remove crank pulley (could be tricky if you don't have an air tool ) remove tappet cover ( you may have to remove the throttle body to do this) Get some flat bar approx. 6mm thick and 400 to 500 mm long. You will see that on the gearbox side of the cams there are slots in the end. Remove the plugs and put a screw driver ( long ) down the hole, any one, and turn the crank untill the piston is roughly half way down the bore. Turn the cams until the plate will sit on the head and slot into the cams thus locking them. The slots are offset so you will have to play around until the plate slides in easy. Then loosen the cam gears untill you can spin them by hand, but not so loose that they are falling off. Put your long screwdriver or preferably a dial guage with extensions into no 1 plug hole turn the engine untill the piston is right at the top. Loosen the tensioner and push it back against the spring and lock it fit the new belt right to left then let the tensioner go. Check play on longest side of belt it should move about 6mm. lock the tensioner. Tighten the cam pulleys and remove plate. turn the engine one full turn clockwise and check belt tension- adjust if neccessary. turn one full turn again and make sue plate slides in when no. 1 piston is on top. Then do a compression test to see if you have bent valves. If the compression test is ok. reassemble and drive away. If not (the exhaust valves are normally bent) you are half way to taking the head off. In which case contact me and I will walk you through it. Good luck Shaun

Disengage the negative battery cable in all models.
Detach the passenger inner splash-shield and wheel cover, the accessory drive and timing belts, the tensioner and the crankshaft pulley.
Remove the spark plugs, catalytic converter and idler pulley in 2000 and older Ford Focuses. These models also require the crankshaft be turned to "Top Dead Center" (TOC) and a crankshaft timing peg be inserted. Turn the shaft to the right against the timing peg.
Undo the retaining fasteners and lift the timing belt cover off the engine. Align the crank and camshaft timing marks. Older models call for undoing the water pump pulley and valve cover before locking the camshaft in place.
Release the tensioner's bolt. Turn the arm to the right 14 degrees and place a 1/8 inch drill bit in the opening. This secures the belt tensioner in place.
Take the timing belt off.
Replace the timing belt counterclockwise motion beginning at the crankshaft.
Unlock the tensioner. Recheck the timing marks by turning the crankshaft two rotations to the right.
Tauten the tensioner's pulley bolt to 15 to 22 foot pounds (20 to 30 Nm) in 2003 and younger models and to 17 to 20 foot pounds (22 to 28 Nm) in older Focuses. Remove the crankshaft timing peg. Reconnect the crankshaft pulley and secure to 81 to 96 foot pounds (110 to 130 Nm) and 81 to 89 foot pounds (110 to 120 Nm) respectively.
Replace the splash shield, front wheel, timing belt cover, accessory drive belt and tensioner and any other items that were disconnected.
Hook up the negative battery cable. Start the engine and check that the timing belt is functioning properly
