So I have to replace the radiator in my 2003 Ford Ranger 4.0L V-6 - it made it 235k before starting to leak, pretty good run. According to the Motorcraft coolant chart (Google it), I should be using: Y = Yellow-colored engine coolant approved to Ford specification WSS-M97B51-A1 (Motorcraft® Gold Antifreeze/Coolant)
Probably 30-50k into ownership, first 2.5 years maybe I owned it, I got a coolant service and they put green in at the Ford stealership, never noticed it until many miles later. Next service at 100k or more they put green in again. While I've had the leak, I've been filling for a long while now with Prestone Cor-Guard 50/50 pre-mix.
So my question is: What the heck at this point should I run? I'm willing to, before putting the new radiator in, drain all the Prestone out, run distilled water through it, drain that and put in 50/50 Motorcraft Gold so it's in the block and heads (it's of course Winter here in Chicago area, so freezing temps can't leave the water in there), then do the radiator replacement and fill with Motorcraft Gold.
But, at this point, is Motorcraft Gold the best coolant I can run, or is there better stuff on the market?
Thanks for any help and/or opinions here!
