queeeesssstion - tranny cooler lines

[4drpower]

hey on the tranny cooler lines "the two rubber hoses that connect to the cooler on the side of the radiator" does it matter which line goes where? i know there is two of them i had a bolt in one to mark where that one went but the bolt fell out of it i didnt know if one hose was for the top and one for bottom or if it mattered??? so waiting on a response

Here is a diagram from All-Data

Yes, it DOES matter. Coolers are designed to work most efficiently with the fluid going in a specific port, otherwise heat-transfer is reduced.

Also, our cooler has a thermostatically-controlled bypass to help the fluid warm up in winter. If you hook up the line backwards, the bypass *may* not work correctly...not positive about this, but I don't want to be the one who finds out the hard way.

Ok so which line is which where is 3 and 4 supposed to go into the transmission

in = hot fluid

out = cooler fluid


Start the car for a second to see which line squirts - that is the "in" line.

First off, is that the correct diagram for the Marauder? Doesnt look quite right to me.

You want to use the factory cooler, then direct the fluid to the aftermarket cooler (unless you have a ginormous aftermarket cooler)

So in your case you'd be looking for the 'out' line from the factory piece.
