Coolant Leak/Overheat

[93mkviii]

Well my brother was driving the car so i don't exactly know what happened. He was stopped in line with the a/c on. He noticed the a/c stopped throwing cold air so he shut the a/c off. The car then threw out i guess a beep and check engine temp. He then saw the needle for temp was all the way to the red and he pulled over and there was radiator fluid on the ground. Move forward to when i got the car in my hand and i checked for radiator fluid. Some was on the battery and on the left tire rods and also on the bumper in drops. I pulled off the radiator reservoir to check for leaks. I added fluid and didn't see any leak come from the reservoir but there was a constant leak, however, i could not see anything on the ground or up top. It stopped at around 1/4 full. I added enough to fill the car and turned it on with the a/c. There still was no leak on the ground(Hoping pressure of radiator fluid moving would further expose leaks) and the a/c was cold. Turned it off and the level of the radiator fluid was still full. Turned it on again to see if the fan turned on when max a/c was on and it did(So fan is working). It's been sitting for a day and it still went back to the 1/4 level and still no puddle on the ground. Any help would be appreciated. And am i looking at any major damage since the car overheated? Seemed to idle fine when i turned it on.

I am assuming the cooling system has been burped properly. You did fill at the crossover tube and not just at the reservoir, correct?

No, I lack this kinda knowledge. Filling at the cross over tube is recommended since it's the highest point of the cooling system?(I don't exactly know) So how would i know how much to fill at the crossover tube? And burping the system is opening the cap at the crossover tube and letting the car run, right? BTW what's causing the leak? Was it a bad water pump that caused the car to overheat and that made the radiator fluid come out?

I had a similar problem, overheating, antifreeze everywhere. Turned out to be a stuck closed thermostat the coolant was spewing from under the reservoir cap.

You need to get a coolant pressure tester and pump the system to 16lbs and check the gauge. If its dropping in pressure you should see coolant somewhere. When air gets in the system, it can cause it to burp from the reservoir ...

Very important to not drive these cars with a leak

It's standard for the burp procedure to be on a sticker, located on the upper frame rail by the coolant bottle on a 93

The fan quit working. You need a new fan. This happen to me in my CE about eight months ago. A new fan, refil and burp, and she'll be good as new.
