Changing the timing belt on my car. Need advice.
From : leviathan
Q: hi. i have an 86 mitsubishi cordia and i am trying to change the timing belt on my car. im waiting to see if someone will lend me a chain wrench in order to remove the pulley in the crankshaft spot. in the meantime i thought id ask a few questions. after i put both the cars timing belts properly aligned will the car be good to go after everything else is put back exactly the way it was for example will the spark plug cables work in the same position as they were before the belts broke or will the cables need to be readjusted somehow what im trying to ask is is there another step after you install the timing belt for some reason i think that im going to install the belts and the car is not going to work properly. any tips thanks .

from fatchance@noway.now tbone with the type of questions that you are asking are you sure that you want to do this job yourself this is not an insult just an honest question. i understand. no insult taken. i have to do the job myself or basically be without a car. i cant afford to pay $240 to fix this. why are you replacing the belt did it break or are you just replacing it do to maintenance if the belt broke you need to find out if it is an interference engine or not. it broke but its not the type that breaks the valves when it breaks. if it is you are going to probably need much more work done to it then replacing the belt. if the pulleys are properly aligned when the belt is put back on everything should work just fine provided no damage occurred due to failure. firing order is determined by the configuration of the cam and crank not the timing belt. there are no extra steps. be careful not to damage the pulley with your chain wrench. awesome. thats exactly what i needed to know. finally an intelligent reply i posted this to several different group. ill reinstall the cables exactly the way i removed them when i put the distributor cap back. i was worried there were other steps after aligning the belts. can i turn the car on for a few seconds with the timing belt correctly installed but before putting all the pulleys back the reason why i ask this is because i want to see if the engine works ok after installing the timing belts this car has 2 timing belts... its sohc though. i wouldnt want to put everything back together thinking i installed the belts correctly only to discover that i made a mistake and i have to tear the car part again. thanks. .

from fatchance@noway.now tbone i dont have in-depth knowledge of this particular engine but i dont see why you cant do that although you shouldnt have to. just remember that in this condition the car has no charging or cooling system so running it very long this way is not a good idea. make sure that nothing will fall into the moving timing belts when you do this. =a0 is this a v6 engine in this car if so even though you may not have the money to have it fixed professionally i hope that you at least picked up some type of service manual for it to make sure that you lined the timing marks on both cams correctly. if not you could be running in circles. its a sohc 1.8 turbo non-interference 4 cylinder engine. i have the haynes service manual which covers various models this this make car and i also have the factory service manual for this specific car. you know what i would like someone to explain you know the part where you have to remove some engine plug & stick a screwdriver through some hole to see if the silent shaft is in the correct position when is this done is it done after installing the smaller timing belt correctly aligned and is the screw driver kept in there while installing and aligning the larger timing belt why is this done .
