Could someone please walk me thru on how to change a broke timing belt. I just got the car for my daughter. Thank you.

it is to lengthy to copy and paste on here either rent a manual or buy one they are available here. However that is an interference engine so you probably bent some valves due to belt breaking. so you may as well pull cylinder head and check

Hey Craig,

You must do the usual disassemble of the engine front starting with the serpentine belt and the timing belt cover, and any accessories that must be removed to gain access. then I have found these images for you to help you along, there are two belts so you must get them both, also check the oil seals on each of the camshafts and the crankshaft and replace them if they are leaking. Let me know if you have any problems.

only after filling with gas, car does not start. Will spin, but no start. After trying it several times, car eventually cranks, and no problems after that. But as soon as I fill it with gas, get in the car, it does not want to start.

The only thing I can think of is you are sturring up dirt in the tank that must be plugging the filter. Have you ever replaced the fuel filter?

Thank you for your reply....I dont know for sure if the fuel filter has been replaced....but the symptoms are very strange...the customer claims that ONLY when he fills the tank, gets back into the car, it takes longer than normal to crank....and he also claims, that when it does finally crank, it acts as if he has to clear it out..likes its flooded or something.....I could not duplicate his complaint, but he keeps insisting it's a problem...I spoke with the Kia dealer in our erea, and they have had no complaints of this nature...checked tsb's, and nothing related to this problem...any and all your input would be GREATLY appreciated....and once again, thanks for your response...Tony....GMAX AUTO...MT. PLEASANT, NC.....

Tony,
The only thing I can think of is dirt in the tank that is causing the problem. However, one would thing that would get moved around regardless of how much gas he gets. I never heard of this type of problem and like you said, there are no TSB's regarding it. I think I would start by checking the fuel pressure and replacing the fuel filter to see if that helps.

USER NOTE: There is a small solenoid valve around the intake that goes bad when this happens

Thanks for the advice. I really do appreciate it. This may be one of those problems that has to get worse before i can find it...I'm sure you know what I mean..Thank you very much....Tony

Let me know what you find.

I sure will..and thanks again

All the timing marks for a Kia Optima 2.4liter 4 cyc.

Hi there, Timing marks for Kia 2.4L Mark (mhpautos)

Engine Performance problem
2004 Kia Optima 4 cyl Front Wheel Drive Automatic

I just installed a new timing belt on anOptima 2.4l and had all my timing marks lined up. I was wondering if there is a 2-1 or 3-1 ratio from with the crank sprockets? If I turn the crank 360 degrees and check my marks they are off by 180 deg.
Doing that also offsets the oil pump sprocket. Why can't I get this thing right? I had originally put marks on the sprockets but have since adjusted them. I had the belt on and started the car but it ran real ruff so I took it back off reset the sprockets again, turned the crank, clockwise once, then checked the marks and they weren't aligned. HELP!!

believe it is a 2 to 1 ratio. If you had the car running and it was rough, chances are you were only a tooth off.

Installation Install crankshaft sprocket "B" onto crankshaft. Ensure flange is properly positioned. Lightly oil outer surface of spacer, and then install spacer to right counterbalance shaft, with rounded edge of spacer inward. Install right counterbalance shaft sprocket. Tighten flange bolt tightly by hand. Align timing marks on each sprocket and on front case. See Fig. 4 . When installing timing belt "B", ensure there is no slack in tension side. Install tensioner "B" in center of pulley on left side of mounting bolt, and in pulley flange toward front of engine. See Fig. 5 . Align timing mark of right counterbalance shaft sprocket with timing mark on front case. To tighten timing belt "B", lift tensioner "B" so tension side is pulled tight. Tighten bolt to secure tensioner "B". DO NOT turn shaft, or belt will be over-tightened. Ensure timing marks are aligned. Ensure center of span on tension side of timing belt "B" can be depressed by hand. Ensure belt deflection is .20-.30" (5-7 mm). Install crankshaft sprocket flange and sprocket. Ensure flange is mounted in proper direction, with chamfered side toward block. Install special washer and sprocket bolt to crankshaft. Tighten sprocket bolt to specification. See TORQUE SPECIFICATIONS . Insert long screwdriver through plug hole in left side of cylinder block to hold counterbalance shaft in position. Install oil pump sprocket, and tighten nut to specification. See TORQUE SPECIFICATIONS . Install camshaft sprockets, and tighten bolts. If auto tensioner rod is fully extended, place it in soft-jawed vise, and compress rod until hole in rod lines up with hole in auto tensioner housing. Insert stiff wire to hold rod in this position. Install auto tensioner, leaving wire in place. CAUTION:If timing marks on camshaft sprockets do not line up properly, DO NOT rotate sprocket more than 2 teeth in either direction, or valve and piston will touch. If necessary, remove and reposition camshaft sprocket. Install crankshaft sensor. Set timing marks of camshaft sprockets with notches on upper side of rocker cover and dowel pins straight up. Align crankshaft sprocket timing marks. Align oil pump sprocket timing marks. Install timing belt in order around crankshaft sprocket, oil pump sprocket, idler pulley, exhaust camshaft sprocket, intake camshaft sprocket and tensioner pulley. Gently raise tensioner pulley so belt will not sag, and then temporarily tighten center bolt. Ensure timing mark of each sprocket is still aligned. Remove wire from auto tensioner. Rotate crankshaft 2 complete turns clockwise. Leave in this position for about 5 minutes. Measure auto tensioner protrusion "A" (distance between tensioner arm and auto tensioner body). Ensure auto tensioner protrusion is .22-.35" (6-9 mm). See Fig. 3 . Install timing belt lower cover and upper cover. Fig. 4: Identifying Front Case Timing Marks Courtesy of HYUNDAI MOTOR CO.

I have decided I don't have the time and obviously the expertise to resolve my issue with the timing belt so, I have swallowed my pride and had it towed to a KIA dealership. They are already trying to sell me another car, of course.

They started to diagnose the car and told me that I had the timing out by 45 deg. I had every notch and arrow aligned, I set my oil pump, made sure the crank balance shaft was in position so I don't really know how I could be 45 deg. off my timing. Am I missing something here, or are they jerking me around? He also told me that I had 0 compression on cyl. 1 the others are fine. I did look down in the cyl. and saw no damage at all to the top of the piston. How is this all possible?

I figured maybe I bent the crank sensor reluctor ring a bit and that was why it wasn't starting. The car would turn over, had spark, but would not fire. I'm just baffled.

Anyway, thanks for your help, I had already joined the kiatechinfo.com site and had read a bunch on it. I also talked to two different techs on the phone and they both told me that I, first of all, was brave to even try, and second if I had everything aligned I was okay. Thanks again!

for you to have the timing out by 45 deg you could have been using the wrong mark ?? from your description of the time you took setting up, I do not think you did this ? for you to have no compression on #1 it must have bent valves somehow ?? bent valves would explain the non start !! after the intitial setting up of the belt you should have rotated the motor twice not once to get the marks realigned ... even so they would have been aligned !! were you just replacing for a new belt ? or replacing a belt that had snapped ??

Hey Dave, it was not broken , I just decided to replace it because the car had 90k on it and I felt like I was pushing my luck with it. I did turn the crank 2 times to realign and everything seemed good. If I had any thing off alignment I guess the only thing I could question would be the crank. I read that the dowel pin should be at 12 o'clock but I also read that the notch on the crank sensor reluctor ring should be lined up with the notch which throws off the dowel alignment. I ended up lining up the notch instead of lining the dowel to 12 after talking with a tech at a dealership.

I am waiting to hear the full diagnostic today the 1st, to see what the verdict is. I am really curious. I asked for all the parts and I feel he should explain how I was so far off my marks. He just said it's hard to explain. Any suggestions?

Install crankshaft sensor. Set timing marks of camshaft sprockets with notches on upper side of rocker cover and dowel pins straight up. Align crankshaft sprocket timing marks. Align oil pump sprocket timing marks.

Okay, so my Timing belt and water pump was recently repaired and everything was running good, but one day I turned the key and it would start(so not a dead battery) but it just wouldn't fire up. A plug needed to be replaced, so the timing belt was removed again to fix this, but when everything was put back out, it was out of time. The pistons(?) Are not properly aligned with the timing to turn over because the gears were turned improperly. They are aligned where they should be, but how can we get the pistons(?) Properly in time to the timing belt without messing up anything drastically?

Warning engine is an interference type meaning if crank is rotated without Tbelt or out of time pistons will contact valves causing damage. see figure shows correct position of aligning marks

What is timing belt “B” I keep reading about it in the motor manual and do you have to replace it when replacing the regular timing belt and should you replace the water pump as well, I want to do the job properly without over doing it. Oh what I would give for a old Chevy timing CHAIN right about now..

Thanks
Lee

Hello and thanks for donating Timing belt "b" is the secondary timing belt that runs around the oil pump and it is a good idea to replace both timing belts as well as the water pump during this repair.

I tried to put the timing belt on myself,but can't line it up correctly

I would buy/lend/rent a camshaft locking tool !

directions to change timing belt

I have the right cam sprocket in right timing, but left one is like twelve teeth a head. Can I go back or do I have to turn crankshaft or all three again? So frustrated already!

You didn't list an engine size. If this is an interference engine, 12 teeth can be enough to cause bent valves.

As far as getting each sprocket set to the proper position, welcome to our world! When you loosen the timing belt, the crankshaft will stay where you put it, but the camshafts will usually rotate due to the pressure from the valve springs. Also be aware that if you do have an interference engine, you may not be able to turn a camshaft to top dead center if the piston is already there. Instead, rotate the crankshaft backward about a sixth of a revolution. That will insure no piston is at top dead center and no valves can be hit and bent. Place the camshaft sprockets to their marks and do something that will hold them there. Now bring the crank forward to TDC, and slide the belt on. The slack in the timing belt will always be taken up on the back side. The length of that part of the belt can vary and is not important. It's the length on the front, where it is pulling on the cam sprockets, that is critical for proper valve timing. Start installing the belt toward the front so it is tight and the sprockets haven't moved. Keep whatever slack develops in the rear where the tensioner will take it up.

Once the belt is tightened, rotate the crankshaft forward two full revolutions by hand, then recheck the timing marks. Always turn it in the normal direction of rotation. Don't be surprised if one of the camshaft sprockets is off a tooth or two. You'll need to loosen the belt and move it on that sprocket. This happens to us all the time.

I have replaced my timming & balancer shaft belt. when I turn it clokwise 2 turns the oil pump cam is the only thats dose not line up. you have turn it 4x to get all points to line up. the 2 upper cams you have to hold them in place after you remove old belt because they turn a little bit. Is that right? Now my car will not start.

It sounds exactly correct ! why did you change the belt ?
