Hello all,
I bought a mk3 supra as my first car...and I don't know much about cars. But anyways, I refilled my coolant reservoir because it was low when I got it, but everytime I drive I found that my car was overheating. So i checked the coolant reservoir again and it was low again. I'm ashamed to say how much I've refilled that reservoir before I realized something was wrong the car. So i felt around and found a whole bunch of coolant on the intercooler. It looked like the right part of the intercooler was sweating coolant. Also, the car sometimes makes a gurgling sound when I start it, which I thought was air in the system, so i bled it out and but it still makes the gurgling sound. Occasionally, a hissing noise comes out from the radiator cap too. Any ideas what the problem may be?

The gurgling sound is air in the system, and if you have a leak it doesn't matter how many times you bleed it you'll keep getting more air in there. You sure it's coolant by intercooler? That's a pretty long way for coolant to go. Is your rad cap holding pressure properly? Get the cooling system pressure tested and you should be able to find any external leaks pretty easily. Have you gone through all the typical blown head gasket checks (milky sludge under the oil cap after a good warm drive, milkshake on the dipstick, coolant coming out of the drain plug first after the car sits for a few hours, white smoke out the tail pipe, etc.)?

That would do it. Would still have a hard time making it to the intercooler from there, but with the fans spinning and whatnot I guess it could be possible to splash in that direction.

Ah NO AHHHH theres a bigger problem! coolant gushes out from the resovoir cap tube..you know that tube that goes from the radiator through the coolant resvoir cap and out into air? i saw coolant coming out of that and out onto the intercooler..WHAT? im scared. haha shit.
