I just wanted to welcome you to the Supra forums, and say congrats on owning a FINE...FINE FINE FINE vehicle...lol.
That little light (Nicknamed the Birdcage), will annoy you unless you top up your fluid about once a week....at least if you plan on doing any QUICK stopping. When you do a quick stop, then the coolant flows out of the overflow hose attatched to that little container. After a couple of those, your whole container is pretty much empty.
Now on to the common problems:
Problem: Blowing Head Gasket
Solution:
1) Keep shelling out cash everytime it breaks to buy a new stock one
2) Mill your heads, and block, buy ARP bolts, and a metal HG, put it together....that is a lasting solution
Problem: Loss of everything electical, car stalls
Solution:
1) one or more of the three common ground wires are loose. They should be checked, and tight'nd back up if needed. There is one at the firewall, there is another right near the battery, and the last is near the starter motor.
2) Your alternator is shot. Get it load tested, if all ground wires are fine, if that is shot, you are looking at shelling out more than 100 canadian.
Problem: Boost guage isn't going as high as it used to, and you notice a small to large loss of power (HP, engine power)
Solution: There is only one thing that could cause this as far as I know. You have a boost leak, this is a hard one to fix, basically you have to check each hose that deals with airflow TO you engine, also check your exhaust system before the turbo...it may be cracked.
P.S. A boost leak is not good....in any sense. The engine CAN be run with it, because its most likely just adding more fuel to your car than what is needed...that is part of the loss of power that you would feel. The other reason for the power loss is that you engine isn't getting all the air that is being sucked in.
Problem: " OMG!!!! WHAT THE HELL IS THAT!!!!! It looks like a cage of some sort...I hope that isn't bad??!?!?!?"
Solution: If you see a yellow/amber light come on, on the left side of your dash, right next to the temp guage, that is your "Warning coolant low" light. You have to fill the container that is to the RIGHT of the LEFT headlight half way. There is a sensor in there that tells you when the coolant is getting low...because we can all guess what aluminum heads would look like after running with no coolant.
there are some more problems that supra have now and again, but these are the most talked about in this forum. Ask most people in here a question..and you will get a good, and explained answer...most of the time. Unless you use bad grammar, and can't spell, and just got your mommy and daddy to buy you the car (IHate****s...lol) <-----
forum joke...you might not get it, but PM me, and I'll explain.

Our Supra’s, which art in the driveway,
Hollowed be thy power, thy mods are great, thy speed endless,
On the road or at the track. Give us this day free of cops,
And forgive us our impound charges, as we forgive those who are slow.
And lead us not into speed traps, and deliver us from the interceptors,
For thine is our car, the power, and the glory…forever and ever….amen.
