I've had to refill my radiator fluid tank up quite frequently lately. The engine us running at a higher temp than normal. I knew there was a leak somewhere. I found the leak on the top passenger side of the radiator. There is a small amount of buildup on the corner and a drip trail below it. Any clues on how to fix this, or would the whole radiator need to be replaced? If I keep the fluid up, is it safe enough to keep driving for now?

 

Check around to see if you have a good radiator repair shop nearby. I once had a leaking radiator on an antique tractor (circa 1950). I thought I was toast because there are no parts available for it. Turned out that a local radiator shop was able to find a leak, solder it. They pressure tested the whole thing afterwards to make sure it was all holding together. Hadn't leaked since.

Forgot to mention, don't do the mystery radiator leak repair remedies. They may work in a short run, but it is not a long term solution
