Default Radiator Chemical Cleaners/Flushes, Safe?

How about using chemical radiator flush treatments (radiator installed). Are these safe? I just replaced the UIM & LIM (upper & lower intake manifolds) and so I don't want to take a chance of damaging seals or gaskets. I appreciate any advice on this subject.

Also: Due to my above paranoia, I may just get a new radiator. Anyone have good replacement recommendations (i.e. brand and suppliers)? Thx

Did some searching here. I might try Radiator Express as others have.

Default No comments, eh?

From the lack of comments, I'm gonna assume that no one wants to go out on a limb and say these chemical radiator cleaners are perfectly safe to use. I guess its a new radiator for me. I'm sure that'* the best route to go anyway.

OK, thanks Ted. Maybe I'll give it a try.

P.*. I went ahead and got a new radiator from RadiatorExpress. For $136 delivered. Why not.
