Ended up relocating the primary trans cooler. It was just too tight below and with the added swinging door support so move it did. You can see both rear opening doors in this shot also. | (1 Comments) With the wider and somewhat lower radiator it was necessary to open up some more air ways. I cut an extra two rows just below the existing and widened the lower valance with additional vents. The new location for the exhaust is also visable. Lots of time involved here as new bracing was needed as I made the louvered section behind the radiator swing out like the drivers side door. | Nice to have things going together for hopefully the last time. Lots of radiator in this shot. | Inside face of the insulation. | ||
I had some heat blanket left from another project so used it to wrap the muffler. Best to keep all the heat possible out of the engine compartment. | Here you can see the angles in place. Installing them should be a simple job if needed. A lot easier doing it now than later on the road. | I'm using an electronic operated fan clutch but am trying to look ahead to any issues with the fan not locking tight enough to cool the engine. I've modified the fan clutch mounting hub by adding some 5/16" grade 8 studs and will have 6 angle brackets which will lock the fan solid if needed | Here it is mounted. I was lazy and didn't want to pressure test again so I just slopped some JB Weld around the welds just to be sure there are no leaks. | ||
(1 Comments) Holley came out with a new universal (almost) fuel level sensor. It uses lidar to sense the fuel level without floats. Wish it was out before I modified the one I have. Simple 1" hole but tapping those 10-32 holes in a 3/8 plate is a bit dicey. | The new larger engine oil cooler required a bit of surgery of the frame for oil filter clearance. Hated to do it but its stronger now than it was before with all the strengthening. | The Allison trans has provisions to mount the dipstick on either side. Some of the mid duty trucks have a longer tube/stick that exits to the opposite side in a much better location for this swap. I did have to do a little massaging to get it to fit but its a lot better than the original trucks location,which was almost impossible in mine. | (1 Comments) The oil fill has a handy telescoping feature to 'hopefully' help with the potential mess of adding oil. | ||
