I put a tranny cooler on about a year and a half ago.

it was a basic one but when I was towing a 10X8 trailer when coming down to florida.

I was doing PM on the blazer and noticed that where I ran the lines, behind the passenger headlight, the lines were a little pinched but one was about to bust.

Now these hoses I put on were for the tranny cooler... If that busted I would of been in a heap of S*it!

So if anyone has their tranny cooler lines going behind the passenger headlight, you might just want to check them....

So I put it back to stock as I cannot find a way to route the lines without an obstruction.

But the Blazer is retired from towing a trailer or whatever, that is why I bought a Stowaway2 if I need to move or just to put stuff in it.

 

I run a B&M SuperCooler on our Blazer. What I did was drill a Two inch hole through the radiator support next to the battery. Then took fuel hoes & cut it to fit around the hole so there were no sharp edges. That has worked for a few years now without any problems.
