Car Problems (overheating)

edited May 2008 in Help / Advice Forum
I've had this Ford Contour for about 3 years now, and every 2-3 months I have to put about a grand into it for repairs. The new thing my car is doing (though, truthfully, it's been like this for about 6-8 months but it's gotten MUCH worse now) is overheating.

Basically I'll put in engine coolant and it'll be fine for.... 2 weeks max now. Then the dial will start indicating that it is overheating. Each time I look at my coolant it's always BONE dry!

I've looked around for a leak but haven't seen any. So do you guys have any ideas what's going on? Is there a radiator fluid or something that is screwing up? Should I be worried about this? Also, when I turn on my heat to hopefully release some of the hot air from the engine (sorta cooling it down) more often than not it's shoots out lukewarm air for 5 minutes, then 1 minutes of blazing hot air. Is that a bad sign?

Alternatively, where would one go to find information to fix cars? I'm tired of being raped by the mechanic. I swear I've put my mechanic's family through college.

    Next time you fill the coolant, let it warm up with the radiator cap off and see if it's bubbling. Because it sounds to me like you might have a blown headgasket, which will definitely cause those symptoms. (other things to look for include a brownish-white milkshake-like substance in the radiator - that's oil mixing with coolant)

    I have to fill it up today. So fill it up, but leave the cap off and see if I notice any bubbling when I turn it on? That might be something I can do. :P

    Yeah that part is really easy. Make sure you're distinguishing between it bubbling because it's getting the air out (if the thing is bone-dry, it will bubble a bit normally and then stop) and if there is an actual leak - if there is, it will keep bubbling.

    Sweet. If that were the problem, about how much am I looking at for repair? :( I literally just got finished paying ~$800 to get new tires/alignment/fluids/flux capacitor in my car, so I'd hate to have to pay about that much again.

    Unless you guys think it's important, then I will.

    Headgasket isn't usually very cheap, its even worse if the head is warped, but you would be seeing white smoke coming out of your exhaust from the coolant boiling off in the exhaust manifold. My guess is you have a leak you just haven't found yet. Have you taken your radiator to a shop?

    If it is the head gasket it's a critical fix. Driving too long with overheating problems can warp the head causing much worse problems. And it's not going to be cheap.

    Honestly, if you've had this car for 3 years and have been putting $1000 into it every 2-3 months why are you even still driving this car? You could buy a cheap used car for a couple thousand that won't require that much money that often.

    Headgaskets are a) very important and b) not cheap to replace.

    Yeah if the coolant isn't bubbling, I'd take it in to a shop and have them see if they can find a leak. That will involve spending money on an hour or two of labor, like $100-$200 depending on where you go, which is why I recommend the bubble check first.

    Because every time I start to save up I get hit by another repair. I can't take out a loan, because I'm already up to my balls in student loans that I don't want to add MORE debt to myself.

    I'll have to wait till the parents come home to see if I notice any bubbling. My dad put the coolant somewhere and I can't seem to find it. I'll report back what I see.

    Do you guys have a preference on who you take it to? I'd rather not take it back to the last place (Big O Tires) because every time I do I end up paying out the ass for stuff. Even if the guy was nice.

    Are places like Midas or whatever any better than another place? Or does it really matter on who's working there?

    I prefer not to go to franchise shops such as Big O or Midas. They tend not to pay well, meaning the mechanics tend not to be as great at their jobs. They are very much encouraged to rush rush rush to make more money.

    I would check sites such as Yelp for independent shops in your area. But yes, it really does boil down to whoever is working there.

    I had a real good one back in the day, but unfortunately you have to schedule an appointment, and then it usually takes him a few days to fix it, and he is about 20 minutes away from here... Which is bad when you're in class and work. But I may call him up and setup an appointment for next Friday, and let him do his business all weekend if possible.

    He's independent I think.

    That is absolutely what I would recommend. In general, if a shop is busy enough that you need an appointment, that means they know what they are doing. You get what you pay for, etc.

    If you don't expect it to get below freezing any time soon, water works just as well as coolant.

    Second'd for the independant shops, but I'd ask around your friends and people at work, that's how I found my "guy".

    And I had a blown headgasket in my Nissan Sentra, did exactly the same thing, overheating. I think it cost around $400-500 to get fixed.

    And when you ditch the Ford, I recommend an import. Personally, I'm still with Nissan, but my family's also had excellent results from Toyotas and Mazdas. My 92 Sentra went from 169000 to 289000 over 3 years with less than $3000 in costs for regular maintenance and repairs, and so far my 98 Pathfinder has gone from 149000 to 320000 over 5 years with less than $3000 invested.

    Oh don't worry.... As soon as I get the funds to get a new car, I'm never buying American again. I can't complain TOO much because I got a good ass deal for my car (it was my fiance's brother's car, and he sold it to me for $650) but since the purchase the car has gone downhill in quality.

    I was thinking a Nissan or Honda Civic. I want one with good gas mileage (duh, who wants one with bad gas mileage?). Supposedly buying a car from a place like Enterprise is a good idea, but I've not looked into it just yet.

    I would recommend staying away from Enterprise. Have you ever seen how people drive rental cars? :)
    Carmax and Craigslist are your friend though.

    Well my friend bought one from there for dirt cheap and it looks flawless, and my fiance bought her for dirt cheap and it's still running after 6 years. But that could just be luck, as I must have killed a Car God in my past life or something.

    So I put in the coolant, at right above the MIN line, and turned on the car. I saw a few bubbles then it stopped and didn't go. I can't tell if that's a good or bad thing, heh.

    This is wrong, antifreeze also raises the boiling point by up to 30 degrees, and that can be crucial depending on your car and location.

    @OP: I'd take it in to the shop and have them take a look at it, you must have a leak somewhere.

    Also check your oil and see if its above the line. As water in there makes the level raise and normally means a blown head or gasket.

    Also note that radiator fixes are fucking easy to do, especially if it's just swapping a house out. If it isn't the head gasket but is instead just a leaky hose or radiator find a guy with some jacks or ramps and buy the part at Autozone. It seriously took me more time to jack the car up and down then to swap the radiator out on my Eclipse, and I saved like $500.

    I'll have to talk to my friend Jerry. He may be able to help me out with this. I'm so terrible at cars it's not even funny. I'm thinking I should really take a class at a local uni to learn something about repairs.

    Checked, and it's at the normal level.

    Monday I'm going to give my old mechanic a call and see about how long his "backlog" is, if I bring it in on Friday that week (the only day I don't have class).

    Thanks for the help guys, I really appreciate it. :)

    I know this is a silly question, but are you seeing a significant amount of water dripping down from under your car after you've been running it?

    I.E. My car will start leaking profusely after turning it on 1 minute1, but I narrowed the problem down to the return hose from the heater core and will fix it within a few days.

    That's generally a good indicator if it's a hose/clamp leak or if it's going through the engine.

    Nope, I don't notice any dripping. I've had someone look under my car after I drove ~10 miles, but nothing shows up. It's really odd.

    sounds like a head gasket problem. is there coolant in the oil when you change it?

    If there was his oil level would be higher and murky in color which he checked. It honestly doesn't sound like a head gasket problem because of this.

    Nope, I changed my oil about 3 weeks ago and didn't notice anything... And this has been going on for a lot longer than 3 weeks. :(

    Just gonna point out that coolant/oil mixing is a common symptom of a blown head gasket, but it won't always happen that way. Depends on how the gasket blew.

    Also, there are other spots that could be leaking, such as the heater core. You'd definitely need to get the system pressure-tested at a shop to find that. (since you're not complaining about funky smells)

    and since the coolants been filled up you've left it running for a few minutes then checked for a leak? Also try running the heater as well, as a separate test, and see if you see any leaks.
