I have been noticing anti-freeze on my driveway where my car was for about a week now. One day I popped the hood and reached under to grab the latch and felt anti-freeze, then I opened the hood and saw that it looked splattered in that general area and it looks to be coming from the top of the radiator. The other smaller looking radiator thing in front of it looks to be wet with anti-freeze on the top left area. What I am asking is, what should I do? Do I replace the radiator? or something else?
I have no problem installing a new radiator but I just don't want to buy it and install it and still have the problem. If someone knows what I should do please let me know. Thanks!
The car never comes close to overheating either. Went from Michigan to Illinois without overheating and vtec on pretty much the whole way there.

you have to find the leak first. top up the antifreeze, start the car and watch for the leak. if it is the rad, try an aluminum filings stop leak powder. may plug a leak.

No testing is necessary. Go to the radiator garage and they will fix the car. Never overheat the engine -- watch the gages...
