Perfect! I have a '98 Wrangler, but no coil rail on her...my son has an '01 that does and this was a huge help before we dive in. Much appreciate you for taking the time to educate...THANKS!

Hey we changed the plugs, wires, cap, and rotor and it made a big difference! Thanks for the videos on Jeeps! Any idea where we can find full doors for a 1998 2 door Jeep wrangler 4.0 dark red?

@JohnsJeepGarage 2 жыл бұрын

Glad the video helped. I realized this video has the coil pack rail, I have another one one this site that shows the distributor cap and rotor. Hopefully the combination of both helped. The question about doors for the 1998 TJ. I would first look for a used Jeep parts location in your area or surrounding area. Or possibly a Parts yard or Parts recycling yard. Quadratec, 4 Wheel Parts and Morris 4x4 sell the door frames (no paint or black) and from what I know you have to buy the lock components separately or power and manual systems. That is expensive. Look on EBay or Craigslist and see what you can find. Keep checking with them. Most of the places sell the lower and upper half fabric doors with metal frames.

Do you have a tutorial on changing transmission fluid and filter on a 2004 TJ? Like I said I’ve done it before, but seem to buy too much or too little fluid.

@JohnsJeepGarage 11 ай бұрын

I do not. This is my only video on it and it is on a JK 3.6L. Part of the video shows how I fill it. Normally for the TJ it is 4.0 Qts for the pan drop and about 8.8 Qts for dry fill. I always go cold fill indicator first (first hole) and then heat up by driving at least 15 minutes to get hot fill read (170-175 degrees) and then add. Use ATF+4 for the Jeeps. Thank you for watching!

Do you have to disconnect the rail at the firewall side by number 6

@JohnsJeepGarage 6 ай бұрын

There’s four bolts that hold on the rail 13 mm, I take all four out in the video, and I’m taking the fourth bolt out at timestamp 1:39. Those are the only bolts I have to take out, and I do not disconnect the wire harness. Did I understand your question correctly? If this does not answer your question, please let me know. Thank you for watching our channel.

Will old spark plug & ignition coils cause your jeep to leak trans fluid? Just a curious question

@JohnsJeepGarage 7 ай бұрын

No it will not. Those are 2 separate systems. If you’re leaking transmission fluid on a Jeep Wrangler, TJ, I would ask you to look at two sources. First the transmission pan gasket and a leak around the pan. But, if you’re asking the question because you changed out the spark plugs and ignition coil and then notice a leak, then I can give you a probability of what happened. The actual transmission fluid dipstick tube could have come dislodged and started leaking at the base of the tube. This is something that can be pressed back in. If it came loose because someone was changing the spark plugs close to the transmission fill tube, and somehow pulled up on it and this loosened tube then I can see how that happens. Check the base of the tube for a leak.

are all the plugs on one side?

Yes. It is a straight 6 (in-line 6) all accessed from the Passenger side.

I know this video is old but hopefully you will see this question. What type of tool are you using to get the right spark plug gap? The blue little tool.

@JohnsJeepGarage 7 ай бұрын

It is a spark, plug gap tool. If you send me a message on Instagram or Twitter, which is now called X, I can send you a more detailed picture of it. I just can’t send a picture on KZfaq comments. This one is a MOTION PRO you can buy on Amazon for about $16. This is for checking and setting spark plug gap on almost any spark plug Includes 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 and 1.0 mm gap gauges. It is ‎Motion Pro 08-0579.
