Default Tune up?

My 03 Kia Sedona has 72k miles on it.

Its starting to run a bit rough when stopped. In park its fine, only when driving can you notice a slight rumble when at a complete stop.

I read somewhere that these cars don't need tune ups until 100k miles, but is that really true? Should I look into changing the spark plugs, etc?

Also, whats the scoop with the timing belt? I think I read it needs to be replaced at 60k - am I past due? I have the 3.5L V6.

The don't require a tune up in the old fashioned sense of the word, but they require servicing in accordance with the manufacturers schedule.
Part of that servicing is replacing plugs when required.
I believe if they have platinum plugs then they will only need changing every 100,000kms.
I suspect though your problem may be a servicing issue, and I would check when the fuel filter was last replaced as it maybe blocking up causing lower than specification fuel pressure.

Yes, I would not expect more that 60k mile or 100k km out of the platinum plugs. Air filter element in the air box needs replacement fairly regularly, also oils/filters for the engine and the tranmission fluid all need semi regular upkeep.

It sounds like you have just purchased the vehicle, does it have an owners manual that details the schedule services, and has it been maintained??

Also timing belt is another one that needs replacing at 60k mile I would think.

Also coolant and thermostat should be changed if they havent been, after five years most of the rubbers will need replacing (coolant hoses/serpentine belts) so that will be some time next year for peace of mind.

Best to get the simple ones out of the road first, and then work toward the others depending on how it has been maintained.

We bought it brand new. Oil has been changed religiously every 3-5k miles. Serpentine belt, brakes, tires etc have been replaced. From what I've read in the manual, the transmission doesn't have to be serviced until the 100k mark. Air filter? Good point, thats one thing I don't think I've done, you can't find them anywhere; if you do they're very expensive. I'll put that down on my notes. Have never changed the fuel filter. Most of the work has been done at independent garages - the only time its been to the dealer was to get the alternator replaced. I saw that they wanted over $600 to do the 60k mile checkup, which I thought was outrageous.

Transmission at 100k seems a little hopeful on KIA part, but I guess if you follow their suggestions that is fine. Just from my understanding about 30000 mile or two years for transmission fluid is a good rule of thumb (all this talk about no need to do it seems to be from the perspective of saving average maintenance costs for a car rather than the long term well being of the transmission)

The air filter makes a huge difference, you may be able to find a K&N filter to suit and that should help the car breath a little better. That 60k check up probably included a couple of maintenance items, did it include the timing belt?

I was able to find an airfilter at my local autoparts store (Advance Auto) and it was the same price as any other panel filter.

Don't skimp out on the timing belt service interval. I don't know for sure, but I suspect the 3.5 is an interference engine and a belt failure can be disasterous.

Thanks, dude. There's an Advance Auto near me, I'll check it out tomorrow.

Can anyone else chime in on the interference engine?

Edit: Search is my friend. It seems my 3.5 V6 *is* an interference engine. Looks like I better hit the dealer ASAP.

I would find an independant mechanic to do the change for you - the dealer is going to be VERY expensive.

I don't know too much about Kia's but they might want to change out the water pump at the same time.

Part of the problem is, on several occasions, I've taken the car to independent garages, only to have them tell me to take it to the dealer. I had posted a few months ago about an alternator problem - the garage just shook their heads and said, "take it to the dealer". Believe me, if I could find a garage that would do the work, I'd go there. My local Kia dealer charges $100/hr for service work.

My physician is cheaper.

Surely with the design being the same as the Mitsubishi engine any mechanic who has worked on a mitsubishi would be more than capable of working on this vehicle. Could not imagine it would be any harder to work on, do some phoning around the local mitsubishi dealers to find out their costs, and then some of the independents around the place, might reveal a good mechanic somewhere. Which vehicle has the 3.5l?

I think it is called the diamante over their, its called the magna over here. There are even shops that do big turbo mods to these engines here in Australia, so their must be some shops locally to you that would do something simple like the timing belt and water pump.

Just my 2c worth.
