How do you change spark plugs in a 2004 hyundia sonata

I hope there is a better design on these sonatas with a v-6 as far as being able to replace spark plugs than having to remove the intake. that is some b.s.

Can I replace a drain plug on a 2004 Hyundai sonata

Check fuses under the hood. When the crankshaft sensor shorts, it often blows this fuse. It is a 10 amp fuse. I don't remember what number it is off hand but it will be efi related.

Could be your mass air flow sensor.

hi,
i have attached the image of the spark plugs and their location of them, in your car. Hope your problem is solved.Please rate my solution as helpful.Have a nice day.

If you look closely at the grid you will see small wires within the covering which connect the grid. These carry current. Most likely, there is a cut or break in one of these wires around the location where the grid stops working. I am not aware of any repair to these, but check with a shop as I could be wrong.

Replace faulty crank sensor.

google it or ask the dealer you got it from

You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold
