Default weird car problem

A little over a week ago on my 1995 Ford Escort, I was looking under the hood and thought my coolant might be a little low, so with spring coming and my temp gauge not working, I decided to add some coolant, figuring any extra would just come out the overflow. I added like a half gallon to the car. The other day I noticed that when I started my car, the coolant was leaking out of the top right hand corner of the radiator and dripping down. After the car is warmed up, the "leak" stops. Is there not an overflow on this and this is it's way of Purging some of the coolant? Do you think I need a new radiator? any mechanical insight would be helpful. thanks.

You did not just ask this question did you?

yeah i did, because it only started happening after I happend to add some coolant and it stops after the vehicle warms up. If anything I would expect it to leak when it is warm and under more pressure. I was trying to understand the science behind why this is happening. It's not like it is leaking via gravity, it is being pushed out at the top.

sounds like a new radiator is in your future. tank leaks are very common on these cars.

plastic or metal?

if plastic use something like PC-7 (sort of like JB weld but million times better) and if its metal have it brazed.

*that is if you can find the spot where its leaking.

good luck.

it's plastic. I'm just wondering if maybe there is too much fluid in the rad and maybe an overflow is beings plugged somehow. I don't know... just thought I could get some ideas on what is going on, if it's just a normal radiator leak, or if something else is happening.

Ummmmmmm it is not normal for a radiator to leak...BUY A NEW ONE! You can try to jerry rig it but you are just asking for more head aches, fix one leak and another one will pop up...just like the little boy with his finger in the dyke.

well, i wasn't having this problem until i added that coolant, so if there is another problem causing this leak, I want to fix that before I just replace the radiator, because the same thing could end up happening to the new radiator, you know. So, can anybody explain why it only is pushing fluid out when it is cold, but after it warms up it stops?

is it a crack? or is it where the plastic meets the metal?

crack - i would try some PC-7

plastic meets the metal - just get one from a junk yard and get a money back guarenty on it.

Dude nothing is going to cause a Radiator to leak but a crack or hole in the Radiator it's self. Just because you added coolent does not mean thats what caused it, it was just time to start leaking is all. As far as just leaking when it is cold well when things get hot they expand and maybe it expands enough to seal? Either way if you know for sure your leak is coming from the radiator just do yourself a huge solid and buy yourself a new one and call it a day...I guarantee if you put a new one in it wont leak and there is no bypass valves or any other crap that will cause your new one to leak.

If it is a crack, when you added the fluid you raised it to the level of the crack... hence the leak.

I patched a plastic tank on my old Skylark with stuff like they are talking about and drove it for 2 years daily. I only replaced it because I was trying to sell it.

Holy Fuckin Classic thread. This fully qualifies Sova as a godamn retard. It didn't leak until you added coolant. NO FUCKING KIDDING.


Ever put air in a flat tire? Bet it didn't start leaking, until you added the air.

brand new radiators for escorts are 70 bucks. its a tank leak, either its cracked or its the seal where the plastic tank meets the aluminum core. its very simple, when the parts get hot they expand thus no leak, when it cools off it contracts and leaks occur. this is classic!

Screw buying a new Radiator, put a raw egg in it. Mythbusters says it works.

ok fine. I was expecting that if it was just a normal crack, it would be more of a problem when it is hotter, because the coolant is under more pressure and would want to leak out more. It makes sense I suppose that the radiator is expanding and sealing it. I just wanted to make sure there wasn't some other factor playing a part in this. I'm not refusing to buy a new radiator, I just wanted to be sure that this was the only problem.
