  • what type of antifreeze and brake fluid

    '06 X, 23k miles.

    i checked my fluids over the weekend, and while they were all above the 'add' line, the antifreeze and brake fluid were concerningly close to the 'add' line. i thought it might wise to put a touch in.

    now, reading my manual it is talking about a mixture you gotta make for the antifreeze. i'm a newbie to the jeep world. in my old 91 corrolla, if the antifreeze went low i just went out, bought some, and poured it on in....no mixtures. the wrangler manual warns against mixing antifreeze to what is in there already and says if you do, you should get the system flushed soon after and have the fluid replaced.

    what would you all recommend if the antifreeze/coolant was low?

    For antifreeze, use either the Mopar stuff or Zerex G-05, no "all vehicle" stuff.
    Your good for 150,000 miles or 5 years per Jeep, but I stick with a 30k/2 year drain and refill, and a complete flush @ 100k/ 5 year.

    For brake fluid, just the generic store brand. Just buy a small bottle, because once you open it, it is good for about 6-8 months, since it absorbes water after being opened.

      I agree 100% with Blupupher on the brake fluid. Just make sure it is the correct DOT# and you are golden.

      As far as antifreeze I am not personally fussy. Usually a 50/50 mix with DISTILLED water and you are good. If it is premixed just pour it in. I also am a strong believer in water wetter from redline. It helps the heat transfer between metal to water. I have seen the differances in my racebikes in race trim and it works.

      Blupupher makes a good point about flushing the system. Get the old crud out so you are getting the maximum heat transfer. You would be surprized at how much efficiency you lose with poor heat transfer.

        Well, with the old green stuff, this is true, with the new long life coolant, you need the right stuff.
        Mopar uses a HOAT based coolant, where Dex-Cool is OAT. Mix the two, and you can have issues.

        You are correct on the distilled water, very important for longest life and fewest problems.

          I knew there was extended life and the old green stuff, and that you don't mix them, but I didn't know there was any differance between long life stuff. Good info, thanks.

            Coolant

            From what I have read during the summer just good old fasion water is the best. A 50/50 mix in the winter will do you fine. Also give Red Lines "Water Wetter" in your rig. I added some to mine and while I didn't see a 30 degree drop in the temp, I did notice like a 10 to 15 degree. And we all know with a Jeep every little bit helps.

              Straight water won't lube the seals and rubber lines. Water wetter won't help lower your temps if you are working in the correct range for your thermostat to work. What it will do is allow better heat transfer so the thermostat is not open fully and is regulating properly. IF you are slightly overheating it will allow the system to transfer heat from the block to the coolant and then the rad (or heater core) better which will allow it to work more efficiently and lower the overall temps when the system is at maximum and the thermostat is fully open.

              Hope that makes sense. Basically the temp sensor should read the same on your guage if everything is working as per normal and isn't working past maximum cooling capacity (full open).

                Ok I will take your word for all that. The cooling system on my rig is a mess maybe it is time to flush it and add some different products. Thanks for the info Ex-Racer#2

                  Not only the luberication part, but anti-freeze is also anti-boil, helping to keep from overheating.

                    About the brake fluid. If it is low you may want to check your brake pads. they maybe close to needing changed. As it is adnormal to just lose brake fluid.

                      well, yes you're right, i will need to check. but i haven't checked it in probably 3 months. and it was still between the full/empty line, just a little close to the empty for me to ride around worry free.

                      thanks for the recommendation. i'll check the pads.
