Nope, not a Chevelle. At least it's a Chevy.

Looks like it's seeping around the lower engine oil cooler fitting. It's enough to make a drip and I smell it.

Any chance of fixing this? Tighten up that big speed nut looking thing?

nobody knows about aluminum/plastic tank radiators?

Somebody throw me a bone here?

Tom, since the introduction of those rads, no one here in my area will even give a repair a try, I and us at the shop where I work replace them. Sorry, not much help.

Time for a new one.
