I recently filled the fluid resivoir for the radiator in my 77 Blazer to the top, way more than what the cold line suggests to be in there. After driving it for about five minutes I found a pin hole leak toward the top driver's side of the radiator. What kind of quick fix can I use to make this radiator work for a few days. I need to make a 2 hour trip with it on Tuesday to get the VIN plates straightened out. (Someone replaced the original VIN plate before I bought it and they will not give me tags for it until I get it straightened out.) I have to make this trip tomorrow. Any help would be appreciated.
