my car keeps loosing anti freeze and i dont know where its leaking any ideas on how to find the leak. ps there is no puddle under the car

 

Is it smoking any? If so, do a compression test. If 2 cylinders side by side are low, blown head gasket.

Also check over the entire system (duh) to make sure nothing is leaking. Just because there is no puddle doesn't mean it isn't leaking somewhere.

 

yeah that, or your radiator hoses...thats what i need to replace on mine
