Lets see if I can explain this....car has external trans cooler. One coolant line runs to top of radiator, other coolant line runs to one side of external cooler, then there's a line that runs between other side of external cooler to bottom of radiator......is this right????

 

Anyone??

 

Are you asking if the coolers are in the right order or if the plumbing is routed correctly? either way, both are doable. You can go into the external cooler first then to the radiator or other way around.

 

Most guys just bypass the radiator and use only the trans cooler.

 

OK, the trans coolant line on top of radiator is untouched, the bottom line runs to b&m on one side & from b&m to bottom side radiator

 

???
nope, leave the bottom line on the BOTTOM of radiator as is, come put of top radiator go into ex cooler then back to trans or bypass the radiator complety. IF your ex cooler is mounted with both lines pointing side ways go into the botton line and out the top. if you wish you may mount the cooler with both down will not matter which is in/out.
I would not mount the ex cdooler with both line up

This is what I needed to know, thanks! Cooler is already mounted outlets down.
