1999 Mitsubishi mirage runs really bad after timing belt.

Bad alternator bearing is one possibility. Remove belt and spin everything it drives to find binding part. Other possible is poor alignment of driven parts.

Let's make this easier if you go to your auto parts store and pick up a timing component kit you will have all the parts to do the job .it comes with information on how to replace timing belt and how to set it up I only install kits in my shop so I know that the job is done properly the frist time.

Contact the car dealer parts department or any auto parts store.

it should be one serpentine belt and first you need to loosen the tension arm in order to take the belt off also a diagram could possibly still be there it will be right around the area where the hood latch is

have you tryed looking on youtube as there usually some really helpful steps that you should take but it can be a bit of a faff on trying to find what you want sometimes

about 65 to 75,000 mi.
this is what we call a zero clearance engine, and if it breaks, will bend valves in cyl head.
water pump needs to be done about same, depending on heavy use of the car.

It could be that the valves need adjusting or redone. When they heat up it swells the rubber and the metal. If you have a bent valve it should do it all the time or it could be one of the valve springs is going. Either way it sounds like it is something in the valve or the valve seats or the springs.

The best bet is is for you to buy a Haynes manual for your car. Try autozone; generally available for around $20.

I am not familar with your specific car/ngine but I am familar with Lits in general. I believe your engine is tranvese mounted which means the fan belts are located on one end of the engine (left or right). The water pump is powered by a fan belt so go to the end with the fan belts. You should have an alternator, power steerring, air conditioning and crank shaft pulley that the belts run on. There should aslo be a pulley for the water pump. use the process of elimination to ID the water pump.

This is a hard job to do if you have no experience please don't hurt your self,,,,first raise the car remove tire remove all belts,remove a/c bracket,timing belt cover put jack under oil pan and raise the motor remove side engine bracket set a side remove top valve cover remove the spark plugs and turn the camshaft flywheel clockwise and bring # 1 piston at top dead center (the highest point) check the crankshaft should align at the mark loosen timing tension remove belt,do reverse procedure..
