Hello T4R peoples,
Need your help please. This is my friends truck a 4.0L V6 with about 160K miles on it. The 4R has not been maintained very well for the past several years. Regular oil changes with Mobil-1 Synth is about it. Noticed the valve cover gasket leaking, so I helped my friend and replaced the VC gaskets a couple weeks ago. Noticed coolant reservoir tank empty (had a few drops of pink in it) so I got a gallon of "Asian" Pink at the local car part store and filled the tank half way. Two days later, same thing, was empty, filled it up half way. Did this three times, tank coolant level is now staying in the middle. Checked it late yesterday and BOOM! Oh crap! We have a leak at the bottom passenger side of the radiator. The car will return late today and I have told the owner No More Driving it until I get her fixed.
After taking these pics I hosed down the mess and the car was driven away. Spent the last hour reading here about "pink milkshake" problems (coolant and trans fluid mix!) but that seems to be on the 3rd Gen 4R (?).

Anyone here ever hear about a pink milkshake on a 4th Gen?
Not sure if I have a pink milkshake (sure hope not) yet, but I was shocked to see the coolant splash and dry as White. So my question is; does (pink) coolant dry and show-up looking White and some areas Pink-White?
Looks like (at a minimum) I will be replacing her radiator and a couple hoses for good measure. T-Stat also. I might also modify it and re-route the trans cooler hoses to an external cooler; instead of using the one that is built into the coolant radiator. Any of you 4th Gen guys done that?
Many thanks for any help and replies.
