ok, the weekend brought some progress.
To prepare the engine bay for my swap ( '07 GEN IV " LMG" into '97 2dr Tahoe) lots of things had to be changed. The antilock hardware is now positioned more downward the inner fender to make room for the '07 engine fuse box,
the Chevy toolbox on the driver side had go in favour for the ECU/TCM bracket.




On the passenger side the inner fender had to be modified to form a flat platform for the battery tray. In front if this the '07 coolant expansion tank will be mounted.




Then the '07 Avalanche fans. The pastic recieved some trimming. Then a piece of flat steel was welded in front of the lower radiator mountig platform. The e-fans have two C-shaped brackets that fit into that new crossbar.




On top the original radiator mounting brackets where extended 1" .





Between those new brackets an aluminum 90 degree angle was fittet. It mounts to the modified radiator brackets with four 8mm bolts and the e-fans are bolted to that angle.




All in all a tight (especially on the steering box side..) but sweet OEM looking fan setup.





And the best thing is the E38 ECU of the GEN IV engine controls the fans.
