I noticed on my 1994 too, there's an extra frame support up front. The name escapes me now but it's a 1/8" or 3/16" piece of steel about 6 inches wide that spans the width between the frame rails, welded to the frame on the bottom.
Didn't know 91's don't have that. I call that piece of metal, "the coolant catcher", because that's exactly where it dribbles if you open the drain on the radiator.
Sometimes I wish that piece was bolted on instead of welded, so I could remove it quickly...
Changed my transmission fluid and put a magnefine inline filter on.
I always wondered how that would look. It looks pretty sweet.
I think you got that backwards...
It wouldn't be the first time, but not this time. The flow on my ’93 goes from the radiator cooler to the drivers side fitting on aux cooler and out of the passenger side fitting back to the tranny. I put the filter on the inlet to the aux cooler because it was a straight run and I didn’t have to add any extra hose. I originally wanted to put the filter after both coolers, but this location was easier. I do have to take off the grill to get to it, but that’s only two screws and two clips. I put a drain plug in my tranny pan and I also use the cooler line to exchange the rest of the fluid. I’m hoping to get another 23 years out of this ride.
