The coolant temp. sensor could be bad....or the thermostat could be stuck shut.....there are a few things it could be actually
Sometimes air bubbles get in the radiator after lines or the radiator have been removed. Just run it with the radiator cap open, until the fluid starts circulating ( the temp gauge will drop to normal). You can also see the coolant fluid start moving inside the radiator which by the way is a little hard to see since it will be bubbling from running about ten minutes. Watch your temp gauge make sure you don't let it overheat for a very long time. Did you put it in backward? There really is a right and wrong way on those things. no, it wasnt put on backward.... ============================================================================= no, it wasnt put on backward....
Open the hood, and is the container closest to the front of your vehicle, so when you open the hood you should see a container called a radiator it is long and about 2 inches thick, has big hoses hooked up to it coming from your engine, take the cap off ( it should say engine coolant) the cap is usually silver, push it down and turn counterclockwise. Put coolant until you reached close to the top. here is a link , see the yellow cap? that's where it goes http://democrazy.encikbeliau.com/wp-content/uploads/2009/03/Toyota-supra-radiator.jpg
No it is to big of a cubic inch. But if you have time you can but you would have to redue the main frame and the engine mount.
You have to take off the glove compartment, and some other paneling to get to a little motor with a whole bunch of gears right behind your center console. Just put grease (or Vaseline) on all of those gears, and you should be good to go!
Yes.
First off, check your engine coolant tank. If it's low, then that's the problem. Put more coolant in. If it's at the correct level, then look to see if there's gunk buildup. Second, is your engine overheating? If the engine is not overheating, and there is gunk buildup in the coolant tank, then you may just need to clean the sensor. If there is no gunk in your tank, your coolant level is fine, and your engine is not overheating, then it may be a bad sensor, and you need to replace it.
Engine coolant.

When the engine is cool
Yes, technically speaking, you can start the engine without coolant. BUT... with no coolant in it, you take the risk of the engine overheating and permanently damaging parts in the engine that are critical for it to operate at all. I stress the importance of the coolant because of the inherant risk of having a false sense of security - i.e. "it's okay if I do this", especially since most people don't just it move in and out of the garage and the shut it off right away. They forget about it even just for a "moment" which turns into a few minutes. Before you know it, the engine is overheating and then you have to shut it down anyway to add the coolent you needed to add all along. If the damage is bad enough at that point, you're looking at replacing costly engine parts. So to avoid the reprecussions of being too lazy to do it right the first time, just put the coolent in it and be done with it. It's the best way to go.
The coolant level switch on a 95 Achieva has a sticking problem. If you tap the coolant tank near the sensor the light will go out
To prevent the engine from overheating.
With the engine cold, put it in the radiator just to be sure there is no air gap. Run it for a short time until it gets warm and coolant begins to circulate. Then install the radiator cap and put coolant in the overflow to the coolant level line.
Coolant recovery tank
If it's an older vehicle - no. But a newer vehicle might just be clever enough to monitor the coolant level and refuse the engine to be run empty.
In the coolant reservoir in front of the engine.
The TTR125 uses an air cooled engine, there are no radiators to put coolant in.
