    How to check car temperature?

    I just recently bought this car. Is there anyway I can check the car temperature on my 2014 honda civic LX? because there isn't like temperature gauge on the dashboard like in most cars where there is needle pointing to cold or hot.

    The simplest way is to install a dipstick with a temp gauge in the top of it. True, you wouldn't be able to see it while driving, but you could certainly get an idea once you have stopped.

    If your car is stock you certainly have nothing to be worried about if you are driving it in normal conditions, even heavy traffic in hot weather. But if I was concerned, I would have no problem taking a look when I parked the car.

    If it's really important to know this info. An aftermarket OBDII dongle with a phone app can do that, according to info on this site.

    Some are under $20 and one is a hundred bucks...

    Note: I have no experience with any of these devices, so you may get what you pay for...

    Bought that one for $10 bucks, a cheap blue tooth phone from a pawn shop and use Torque or Torque Pro. You can set up your own digital gauges with the app to show you mostly anything.

    I'm glad your item worked, but in general, read the reviews before you purchase anything from Amazon these days. Most everything is junk. This item received 103 critical reviews.

    I wouldn't even consider a $10 item plugged into my car. If you really want this spend a few more dollars for a quality scanner.

    Yeah, I know I'm a bit paranoid, but I am wary of plugging any low-cost, Chinese-made device into the port that goes straight to the car's main computer.

    My semi-solution to a temperature gauge is part of a multi-feature dash pod that I made for my car. I carefully taped a thermistor (temperature-controlled variable resistor) to the outside of my upper radiator hose, and that goes to a digital thermometer on my custom dash pod. Actually, it's a voltmeter that is customized and calibrated to act as a thermometer, but you get the idea. I put a small piece of metallic tape between the thermistor and hose to try to keep it from making an imprint in the hose, but that is something I'll have to keep an eye on.

    Of course, since the sensor is not actually in the coolant, it is not going to give the true coolant temperature, but I figure that as I recognize what kinds of readings are normal for various driving conditions, I can recognize if the readings are higher than expected, which could indicate a problem with the cooling system. And I didn't have to tap into any engine computer wires.

    I've been using my elm 327 bluetooth ecu dongle with torque pro for 7 years on my 2012 Si. It is extremely accurate, so don't be put off by the price. $10 for the dongle and $2.99 for the android app. It works perfectly and gives amazing results, including coolant temp.

    In fact, I've used this combo to pull error codes from others' cars and to clear them once problems are fixed, too.

    The elm device only works with android though. Apple users will have to resort to similar, more expensive solutions.

    I wasn't singling out any one item. Just cautioning folks to read the reviews before purchasing. Generally, if there are a lot of common complaints about a particular item, I pass, even if there are many more good reviews. Everyone should use their judgment.
