Radiator and coolant :-/

[NiftySVX]

Hey all, how have your transmissions been?

Have been really enjoying my GS 450h lately, but it is starting to get cold and I figure I ought to get the SVX up and running. As most of you old timers know my car is stock right down to the wiper inserts except for the Level 10 transmission. About 5 months ago the top tank on the radiator cracked and poor old nifty has been parked ever since. I am going to get a replacement radiator and thought I would ask what everyone is running. I will not purchase one from any discount auto parts store, I am actually thinking of having my current one retanked if possible. Also, is anyone using the new blue coolant? It's been three years since my last coolant service so it's due anyway, and of course I like my head gaskets and my water pump so I won't use any of that hateful coolant available...where ever people buy parts that aren't stock. I am also considering using the toyota super long life antifreeze/coolant that is pink because I have a ton at the shop.

Who has what thoughts?
