    I started my car and drove around and was flooring it too for about 8min and the temperature was still cold, it didn't even move. My fan was off too. I know the thermostat could be stuck open but after about 12min the temperature needle went up a little bit. The farthest I've seen it up was 1/4 when 2/4 being half. What could go wrong if I keep driving like this without fixing it? Heard that the oil needs to be warmed up to have the engine run properly.

    First of all was it cold outside? This has a huge factor...

    Visually inspect the thermostat, and see if it's stuck in open position. Might need to replace :twisted:

    The thermostat is meant to stay closed so that the car warms up faster, and open when it starts to reach operating temperature.

    If it is stuck open, your car will take a longer time to get up to operating temperature..

    it was cold but not that cold and you said it's a major factor, what will happen? I mean what will happen if i continue to drive with the thermostat stuck open?

    Seriously? Just replace it, its like $20 lol.

    Make sure you verify that it is stuck open first though, check if the coolant is circulating by feeling the upper radiator hose when the car is cold.

    Warm oil lubricates better. Premature engine wear, if it doesn't get up to full temp over short trips you get s**t building up in your motor etc etc. Seriously dude. Spend $12 and take the three tiny bolts out and replace it. Don't be lazy, treat it right and it'll treat YOU right.

    Yes, there IS a good reason you should replace it if it's stuck open. That's why small motors tend to last a long time, they get up to operating temp very quickly and most people do lots of short trips.
