Default Anti-Freeze Dissapearing Act!!!???

My 88 Mustang GT is mysterisly losing antifreeze? I'll wake up in the morning fill it up drive around then have to fill it the next morning. I realized the problem, had it pressure tested and they said it was blowing out of the neck or the radiator and that the cap was bad. The guy being a friend of mine replaced it with a heavy duty radiotor, not name brand, and the same thing is still happening. I replaced the thermostat with a 180d then he replaced it with a 190d. I brought it back to get another pressure test, he ran it for 2hr!! and NOTHING SHOWED UP!? But there has to be something wrong with it!! One thing that might be helpfull is that i was driving on the highway for a while after just filling it. Came home then let it cool, checked it and it was dangerously low. So heat i'm guessing is a factor. My mechanic friend said that since i have E303 cams that maybe that is the reason. IDK, please help!


In case it helps, MOD's

If it is an auto it could get to the tranny through the rdiator also . Not likely but check it anyways to be safe

I second the motion on possible head gasket. Same thing happen with my g/f's car ('99 Olds Cutlass, 3.1L-prone to headgasket problems). She would drive a little and low coolant came on...so we filled it up. Day and a half later light came on again, told her to have it looked at since the car was still under the initial 90 day warranty. Ended up being busted intake gasket. it was leaking slowly as she drove and burned up once it hit the block. Could notice the smell, but it wasn't too strong.

I have a 94 and the same thing was happing to me.Could not find a leak
under or around but at times could smell anti freeze.Turns out I found the leak behind the timing cover, it would hit the block and dry. Hopes this helps.

Thanx, there are no leaks around the car at all, I checked that. But i'll have the head gasket checked out. My oil is fine, so it's not leakin into there. And I dont smell anti-freeze. Thanx for the help, I hope it's not to expensive to fix

bypass the water hoses that are going into the intake, if this stops the leaking then you know that it is your problem.

Dont drive it like that . The coolant lines are there for a reason . Your egr will get too hot and your car may run like crap .

Uuuuuh, your heater core might also be leaking. They are prone to leaking and I think the anti-freeze leaks out the A/C drain hole near the passenger side front wheel.

Turn on your heater and see if it stinks like anti-freeze.
