Hey guys my supra does a wierd bubbleing noise under the dash as I accelerate, does anybody know what that is?

your cooling system is low or there is air trapped in the system . this is a sign of a blown head gasket,however you may just be low on fluid . top it off . if this is the first time . if it continues you most likely have a problem
is this car a turbo ?

Its a non turbo, but im gathering my parts to convert it into a turbo. I dont know much about these cars, but if my cooling system is low what should I buy and where do I put it?

anti-freeze
into the radiator

stock toyota anti-freeze is red

You can actually pull off a few caps and park your car on an incline to get the air out of your system. It sounds ghetto but it works.

yeps

burping the system

take it to the nearest hill or jack it up
take the cap off (engine cold)
start the car and make sure your heater is on max fan speed and heat
when the thermostat opens you will notice bubbles starting to come out of the radiator
once bubbles have stopped and the radiator is topped up with water to full... put cap back on, let car down and away ya go

does your heater work?

It was working, but once I did my radiator flush, I might have done something wrong, and my a/c and heater stoped working.

Do I need to jack it up from the front or from the rear?

front

so that the radiator is the highest point of the engine :)

Thankz, ;)
