Ok well last night on the way home from work I hit a Propane can that was in the middle of the interstate...Luckily it did not explode....But anyways I pulled over to the side of the Interstate and checked my vehicle and it appeared fine except for when I looked under the hood of my car and there was radiator fluid all over my damn engine so I was like wtf and I checked the radiator and did not find any cracks in it or anything at the time and was just thinking that it came from the cap; so I drove it home. Well this morning I go and check it and come to find out there is a crack at the top of the radiator oh about 1 to 2 inches long give or take. Now I was wondering if I was to seal it up with some metal filler would it work and for how long and will I be able to drive like it is for about 2 weeks till I get another radiator without it overheating and losing any fluids???

Any help would be greatly appreciated!!!

Thanks!
