2004 KIA Optima Timing Belt Installation

I am trying to install a new timing belt on a 2004 KIA Optima. I have run into a problem with the tensioner. It doesn't seem to move enough to get the belt on. I tried removing the tensioner assembly, but no matter what I do it is always just about there, but not quite. Also I understand the oil pump has to be timed. Where should the mark be? Please help, I have worn my fingers to the nub trying to get this belt installed. I am probably missing something i am sure.

I have never heard of a "timed oil pump" but there can be a first. Also the timing belt is supposed to be tight. Alot of cars are "interferance" motors. Which means if the timing belt goes all the rods stop where they are and the pistons continue there rotation resulting in smashed rods and valves. It should be very tight to get on, try wrenching on the tensioner when you put on the belt. Even get another person to do one while you do the other. Good luck.

04 Kia optima... I replaced broken timing belt and the engine turns over but doesn't start


Did you make sure the belt was installed with the timing marks lined up properly? If you forgot to look at the timing marks it will not start and you may damage the engine trying to start it.

2004 KIA Optima LX timing belt/water pump


The thing is your doing the timing belt the water pump is right their with it . it should cost you much more at all besides the cost of the water pump. When doing a timing belt I have a rule that I go by The timing belt/seals =cam , crank , any pulley & tensioner & water pump all get replaced at the same time. I did a t-belt on a Audi A-8 very complex whole front of car has to come off as well, he didnt want to do w-pump & thermostat his thermostat was their as well not even a month later the water pump gave out he had to pay double the price because he didnt want to do it when I had it apart the first time. And make sure mechanic is ase certified . good luck

Is the car flashing any codes. I would look for fuel issues possibly fuel filter, injectors etc. Because these items are easier to check. Otherwise it sounds as if the timing is off on the car. If the Hydraulic tensioner is not replaced this could cause the belt to jump teeth as well. PRETTY SURE YOUR TIMING IS STILL OFF
