    Disappearing Coolant

    I seem to be losing a cup of coolant about every other day. I've checked all the common place but I can't figure out where it's going. The car (2003 WRX sedan) is running perfectly smooth. No white smoke out the tailpipes. No leak of any kind. No rough idling. Just a dropping level in the resevior.

    Any ideas???

    send your oil in for analysis. my dad's trailblazer had that problem, and they found coolant in the oil.

    We looked at it over lunch. I can smell coolant. So it much be coming out somewhere. But it's not leaving any on the floor.

    The oil looks fine. It would have some milky stuff in it if the coolant was getting there.

    How to Burp Your Car's Cooling System | eHow.com

    Remember that the reservoir only holds a fraction of the total coolant. When your thermostat opens, the coolant will begin to flow and the reservoir will drain into the system and equalize. Burping the system will remove air from the piping thus equalizing the system for you.

    when i changed my dads oil, it looked fine. it was the analysis results that pinpointed where the coolant was going.

    If you can smell coolant there is a leak. It will have to be located before doing anything else. Have the system pressure tested.

    1. Pressure test the system.
    2. If leak is simple, fix it.
    3. Burp the system.
    4. Burp.

    If the leak isn't simple, please post back and you can get more advice on what to do.

    Looks like a crack in the top front area of the radiator. Sorry for the poor picture. I got home today and took a flashlight to look everything over real well. And there is was, a wet area on the front of the radiator. I guess this is the only leak. The only one I've found so far.

    Very common. Two of mine did that. I now use an OEM Koyo but there are cheaper or more expensive options. If you order watch the shipping cost, it may make sense to buy locally.

    How difficult are they to change?

    the actual removal and install of a radiator is simple. hardest part is draining it, and then filling it back up.

    Left and right mean as you are facing the car, standing at the nose and looking at the motor.

    Remove intake on left.
    Decide whether you are going to use the petcock on the lower left or the lower rad hose on the lower right to drain the rad. Do so. Be prepared.
    Disconnect and remove the overflow hose(s).
    Disconnect top and bottom rad hoses.
    Disconnect two rad fan harness clips.
    If you are willing to fiddle with the steering feed line, you can remove the old rad with the fans still installed; you will have to move the steering out the way carefully and wiggle the rad plus fans out. Otherwise unscrew the fan screws and remove the fans first, then remove the rad by pulling up.

    Burp the system well. Also, your replacement may have a rad cap and your original may not. If so, you will have to tee the overflow from the rad's rad cap into the white reservoir on the right. This is easier to picture than describe.

    Any way to patch that plastic? Can't weld it like a metal one, but isn't there some epoxy and cover material that would suffice?
