One thing I hadn't seen mentioned is did you get a new radiator cap? If you're puking coolant out of the reservoir, that can be a symptom of a failed rad cap, which won't hold the proper pressure and cause overheating (or undercooling at least).

 

I also have the B&M #70264 mounted in our 'yota RAV4 and our GMC Canyon p/u.......have mounted that unit in numerous other vehicles over the years. Never had even a single issue......ever.

 

Yea,B&M products and service has had an outstanding reputation for a lot of yrs. They definitely set the std to go by.

 

I was thinking of doing a tranny cooler once i get all this mess figured out. but how did you go about installing the lines to it? when i replaced the radiator i had to deal with that F-ing stupid "quick" disconnect. it caused me hours of frustration and cursing as i eventually broke the angle inlet off the old rad and had to pry it apart with small screwdrivers. is there a way you mod this out with compression or bard fittings when you do the aux trans cooler?


Oh and yes i did also replace the rad cap.16 psi

 

The top/upper trany fluid line on the radiator is the cool/return line going back to the tranny. That's the line u want to splice the new auxiliary cooler into. We used a small tubing cutter to cut the metal tranny fluid return line about the middle (side to side) and behind the bumper. From there we attached the 2 new rubber lines from the new auxiliary cooler to the 2 metal lines and double clamped the 2 new rubber lines.

Doing it that way, tranny fluid is 1st cooled in the OE factory rad mounted cooler and then 2nd cooled when passing thru the new auxiliary cooler, before being returned back to the tranny.
