Take a little vacation from the car and go back when you're fresh to deal with the coolant issue. Old cars (mk3 supras!) can be frustrating. My supra has taken a healthy chunk of both my patience and money but I love having a car that people will look at for a couple minutes and still ask me "what kind of car is that?". Unfortunately it is usually followed by "you're leaking coolant".

The problem was that my CPS wires broke out of the clip so I had to wire them up around the clip and I had two of them wrong....dumb me.
Well today I bypassed my heater core...and it still emptied out the coolant through the overflow bottle....sux.
The only thing i can think of would be is that my block is cracked...it doesnt happen until the motor warms up. Is there a possibility that it could be my radiator??
I do need to take a break from it and then return later..but I want to enjoy it so bad. If the urge is to bad i take it down the street real quick and back before it can heat up and spit the coolant out.

could be a faulty rad cap, if its old or the seal on it is messed up it wont maintain pressure.

its a new cap as well as thermostat.
Someone before me put that liquid glass stuff in it. U can see it in the radiator fins. So i am thinking that might be clogging the radiator and not letting the coolant circulate...causing it to become hot and take easiest way out.

yea ive heard about that glass stuff. sounds like crap too me.

you could try a flush, but im betting that wont do it unfortunately. theres also the option to boil the rad out, but im still not positive that would do it. you can call performance radiator and im sure you could get one for ur app for about 150.

they are great radiators, ive used them alot and they have great construction and are far superior to an oem replacement.

Test that cap again, new doesn't mean good. Make sure it can hold the correct pressure. If you think you have radiator blockage, you might find it using an I/R thermometer. Is the radiator in good shape (fins, tubes damaged or rotted)? Is everything else in good condition? (water pump, ALL hoses, fan/clutch/shroud, correct t-stat). Test the coolant for hydrocarbon traces if you think the block or HG is at fault.
