Ok, I changed my heater core a while back and everything went smoothly. but now that it has gotten colder (single digits) here in TN, I have noticed that I have a coolant leak when I first start up the engine. The wierd thing is it seems to go away when the engine gets warmed up. I dont notice the leak when I get to my destination. Does the fact that I replaced everything when it was cold out have something to do with it? did I fill my radiator incorrectly?

Any advice would be much appreciated...

Thanks in advance...

 

You don't see the leak when everything gets hot because it's evaporating. Where is the leak?

 

That happens quite a bit, it's caused by the cold and sometimes can be tough to find. When everything cools off and contracts, the tolerances are greater between the radiator, hoses and the water pump. After the engine reaches operating temp, everything tightens back up and that seals the leak.

Try to pinpoint the leak as best you can and then tighten the clamps or bolts in that area, it's best to tighten them while it's cold. Be sure to not over torque the water pump bolts if it's in that area general area, a busted bolt is a pain to remove. Chances are that if it is coming from between the water pump and engine block, the gasket is bad and will need replacing, if you do have to pull the pump, might as well replace it.

If it is leaking from the weep hole in the water pump, then the pump is shot and will need to be replaced.

If it looks like it is comming from the radiator itself, it might be a seam about to give way and there is not much you can do except replace it or have it repaired at a radiator shop.

If your thinking about using some sort of "stop leak" that pours into the radiator, think twice because that can cause even bigger headaches later on.

hmmm... so what you are saying is that I am pretty much screwed no matter what. Should I wait till the temp warms up and see if it fixes itself? or is this a major problem that I need to attend to right away. I just noticed tonight that my breaks are making noises and such and are prolly gonna need a new pair of shoes soon and being a poor college student with high hopes of a nice Bronco, money is in short supply.

Before you throw your hands up and quit, at least try to locate the leak.
