Next up was making sure the radiator, fan and shroud are going to work together, especially since this radiator is taller and narrower than the one that came out. The fan is a reverse rotation 6 blade unit with a fan clutch for an early 90's truck tbi 350.

This large two core radiator is from a company called " Cold Case " and the tanks on it are the same size as a 4 core. Being taller meant I had to cut the top clamp and put some spacers underneath it. A pair of old lug nuts serve as spacers for now. Finishing the top clamp will a punch list item for later.

This is a long water pump engine so the fan shroud will to be adjusted for proper fan placement. I used my stock original shroud for mockup purposes but ordered a new one for final installation.

The fan shroud mounting brackets also needed some help. They were pretty rusty and bent up and in need of seals. So I hammered them as straight as possible and put on new seals. When I test fitted these brackets to see how well the seals looked on the radiator it was obvious the seals were not going seal up against the sides of the radiator. The taller, narrower radiator strikes again. So I made some seal extensions out of a leftover radiator top seal and that closed the gaps.

Got the engine bay side of the a/c system finished up. The condenser, dryer, hard lines and compressor lines all in. Was in the middle of the system wiring when I was chased out of the shop by the heat.

One last thing for today. I used the old choke cable hole in the bezel to install the two position switch that selects and programs features in the Dakota Digital gauge panel. The aluminum knob to the left is the dimmer control for the gauge panel.
