    Default Coolant Reservoir Empty

    Ok, I hate to admit it, but my 04 is starting to worry me a little. Past while, it's been burning more gas than usual, and lacking some power. No unusual smells or anything like that. I started it on Monday and the engine sounded weird but as soon as it warmed up, it seemed fine.

    This morning, started the car - low coolant warning. Went out thinking it was 'another' coolant sensor issue, but no. Low and behold the entire reservoir was bone dry. Weird.

    I'm thinking that it's either three things:
    1. Head gasket is gone and running the car while it leaks into the engine is destroying it.
    2. It might be a simple leaking hose or loose clamp. Car IS 10 years old.
    3. It's just normal usage and I haven't been really paying attention.

    Anyone else experience the same thing?

    Hello Ed,it could be something simple as the seal on the cap.Refill the reservoir but before you put the cap back on take the rubber out of the cap and turn it over.Refit the cap and see how that goes.

    Fingers crossed that's all it'll be.Good luck

    Regards

    I had low light come on... never really checked on a normal basis but once I refilled and I keep checking all has been fine. I noticed our Pilot after 2yrs was low as well, so topped that one off.

    Check the radiator, especially the tanks for leaks. I replaced mine last year with a radiator from IPD, they source from 1-800-RADIATORS. It fit fine, but the core is slightly thinner, and appears to be a lower fin count. If I had to do again, I think I would buy an OEM from one of the online dealers. Not too bad to change, all three cores come out the bottom. No need to dump the AC.

    I'm going to bet that the radiator is leaking since it's very common for them to leak because the end tanks are mounted to the frame and hold the condensor and intercooler.

    I didn't notice mine was leaking until i was changing a fog light light bulb since the radiator is covered underneath with the shield along with the engine shield so they held the leak from dripping on the ground pretty good.

    I would remove the shield underneath the radiator since it's easy to do and take a quick look at the end tanks.

    I replaced my radiator in the driveway with a Nissens brand one from FCPeuro. It's looks well built and went in without a hassle.

    Same thing...found crusty coolant remains by the thermostat housing...very hard to see unless you're looking.

    Replaced the thermostat.

    Or, like mine a while ago, it was a hairline crack in the coolant overflow bottle ... replaced it and all was fine again.
