    Another good explanation J.T. Stellantis must recommend when to change plug wires? My van did not come with a service manual. Something the service advisor could upsell. Coolant change interval as well. Ot much else that can be done.

    • @OnlineMechanicTips
      @OnlineMechanicTips  2 роки тому +1

      Yes, all you mention have service change intervals except maybe plug wires. Its hard to put a life span on secondary ignition parts such as a coil or plug wires ide suspect.

    Very good Video, alot of new techs out there fresh out of school or DIYers just getting started end up running in circles and throwing parts at the engine chasing down the small gremlins, and forgetting the basics, especially a good Ol Italian Tune up can clear up alot of driveability issues, especially on city driven cars

    hi JT, greetings from Poland. Is it possible to use throttle body cleaner instead of combustion cleaner?

  • @franka2507
    @franka2507 2 роки тому +2

    Thanks for the tip. Can the cleaner cause hydrolock in the engine?

    • @OnlineMechanicTips
      @OnlineMechanicTips  2 роки тому +1

      Its more fuel based than water based. You cant compress water. This combustion cleaner will simply blend with the fuel mixture and burn out tail pipe.. I been doing my special liquid valve job for over 2 decades with no problem bud.

    Maybe I'm over thinking this but I would be concerned about a chunk of carbon getting stuck under a valve or possibly scoring a cylinder wall.

    • @OnlineMechanicTips
      @OnlineMechanicTips  2 роки тому

      Nope, you not over thinking anything. Thats a good reason to be concerned. But now I question your motives, are you aiming to remove any carbon build up on these valves??? If so be aware that the break down build up has to go somewhere. It will simply blend with the air fuel mixture and burn out the tail pipe in the form of maybe black smoke. In this case, mission accomplished. After ive done my spray soak, when I finally start the car, it will smoke badly but once it burn off and the cats clean it up, all is well.

      @@OnlineMechanicTips I have had the intake off twice, once for a bad fuel injector and once for a roller rocker (tic) which I replaced and I never thought of looking at the valves. I notice what seems to be a very slight miss while in gear at idle. No miss fires on my scan tool so your video made me want to try this cleaner for the valves. 3.2 with 75,000 miles. Thanks for the great videos.

    Aren't you afraid of hydro locking the engine when spraying the cleaner on the valves? especially on the cylinders where the valves are open. Do you somehow dry it out before start up?

    • @OnlineMechanicTips
      @OnlineMechanicTips  2 роки тому +2

      No im not afraid of that, and no I do not dry it out but I understand your concern. If you read the instructions on the back, it tells you to soak the intake (whether valves are open or not) It will simply compress and burn out the tail pipe. Not restrict the pistons from moving up and down.

    I thought carbon only builds up on the intake valves of engines that have direct injection?
    I have never seen carbon on the intake valve of engines of with port injection. Please advise. Thanks.

    • @OnlineMechanicTips
      @OnlineMechanicTips  2 роки тому

      Theres nothing to advise. Yes direct injection comes with problems like carbon build up in the intake and on the intake valves due to crankcase ventilation but most consumers or diy guys not sure. We just make it a habit to PM and inspect an clean during a tune up.
