    Speaking of coolant levels (post below) it would (

    also be a good time to check tire pressures as well as electrolyte levels in your battery. I just added about 2 ounces to each cell.
    While your at it a brake fluid flush should be done every 12 months in very wet climates and every 24 months for the rest of us. Silicon fluids aren't recommended for every day street driven cars.

    Better yet, get a hydrometer and measure the specific gravity of your battery electrolyte while you have the cells open. This can give you an "early warning" of a failing battery, or a good degree of confidence that you don't need to replace it.

    My 5+ year old Interstate MTP-93 shows electrolyte chemical charge of 100%. I believe this is, at least in part, due to my desulfating float charger. At the same age my factory battery was in the 50% range according to the hydrometer before I had the desulfating charger. I replaced the battery preventively and when I tested it a few weeks later one cell had shorted (probably through sulfate crystals) and it read 10.4V. Just in time - I think.

    Silicone fluid should not be used in ABS. It>>

    That's only one of the many reasons to avoid it.

    I use Ate Blue and Ate Gold. Easy to see new fluid

    when flushing. I got to admit, I never check the electrolites level. I do check for build up on terminals and run my OBC set to voltage gauge.

    CinC, what desulfating float charger do U use?

    I replaced my battery about 18 months ago, (m)

    This was the first time I've unscrewed the caps to look, the level was still above the plates. Use distilled water to top them up.
