That isn't normal. You need to do a cooling system flush and would be a good time to replace the radiator afterwards if it doesn't clean up.

The tubes are probably clogging with calcium deposits.

I'd be tempted to pull the radiator out, fill it with vinegar and let it sit and see if it can clear some of that up. But if it doesn't, you might want to consider a new radiator. Flow and heat transfer can be affected by that.

Any radiator shops near you as new radiators (quality ones anyway) are not cheap. Might be worth seeing if they can clean it up for less money if its not your daily driver.

It would be worth a try, but it looks like faucet water was used in the cooling system.. Take it to an old school radiator shop and get it rodded out...

I'd expect a good radiator shop isnt cheap these days. Even though the core tubes could possibly be cleared, with an old core there are likely other weak points. I'd be going directly to a new replacement in this case,

I agree. I'd try self cleaning with vinegar but dont expect dramatic results. I'd plan for a replacement

Personally I would rather try the "rod out' or even a new core ( if its a quality shop) than some of the new garbage being sold that doesnt fit right...
I know there are some really nice new ones made, but aren't they around $1500??
I also like the brass radiator cores over the aluminum ones...

I drove 30 miles to the only good " old school" one I could find... Charged me $210 to pressure check my radiator and condenser.. They cleaned and painted them too...

Yeah old school shops like that aren't common around here. Major metro area...everyone is just buying new cars and throwing new parts at them. Nobody repairs and it's rare to see a vehicle beyond 15 years old on the road because the salt eats them out. Not enough business for those old school shops here.

You can get all aluminum radiators on Amazon for under $200 easy. I saw prices between $140 and $160

And I actually had this exact radiator in my 93 vert with aod for several years. Had no problems with it and it cooled fine for that particular setup. I sold the car with that radiator in it. Plastic tanks yeah I know. I’ll say this, it was light as a feather
