- 1974 Brown Coupe 454 4-speed
I have a small coolant leak that ONLY leaks AFTER I shut the engine off! At least as far as I can tell. I shut the engine off hot, and after about 2 to 4 minutes, it starts to drip about one drop every 30 to 60 seconds on the passenger side bottom of the radiator about where the tub and core come together. But it's not clear that it's coming from this connection. It can just as easily be running from somewhere else. But it just seems strange it only leaks after the engine is off. And it stops after only leaking about a 2 inch round puddle. I had it out a couple of weeks ago on an 87 degree day in stop and go cruise traffic for 2 hours. Got very hot everywhere. Temperature gauge never got above 200 degrees! No signs of any leaks! Should I check the cap? The over flow bottle and hose? I even put stop leak in also a couple of months ago. The cap, radiator, bottle and hose are all original equipment from 1974.
