Let's see, this is a long list.
* Replaced the air filter with a K&T filter. (I was having thoughts about running without a filter until it came in due to concern about parts breaking off and flying into the engine - it was that bad! I suspect it was the original.)
* Swapped the 800 CCA NAPA batteries from the Chevy G30 over into the CUCV, replacing the 700CCA Walmart batteries. They just weren't cutting it for daily 0F starts!
* Topped off the coolant. It would appear I have a leak, somewhere - it's pooling on the frame/front clip junction area and dripping on the driver side springs. Can't seem to identify where...
* Apparently, previous owner should not be allowed around wires! Spent 2 hours under the dash looking for the fog wires, will likely have to pull the full dash to figure this one out...
* Added a lit 120V harness to the front grille with a temperature controlled 4-way splitter on the inside of the engine bay for: battery heater pads, oil heater, trickle charger, (future) frost plug heater (pictures below)
* Got rid of the stock battery tray tops and put in wratchet straps for securing the batteries (MUCH BETTER!)
* Replaced tin can metal battery terminals with some nice thick nickel plated ones
* Spent several hundred dollars on Amazon et al picking up things to be installed when it's finally warm enough to possibly get a little wet: fuel lift pump, spin on fuel block/filter, thermometer, electric fan conversion, in-vehicle 120V inverter for the rear, and a handful of switches, lights (red LEDs to replace the behind-dash incans and the brake lights) and bobbles for in-cab accessories.
* Took off all but 1 of the side radio antenna mounts, sanded, and painted the different-color exposed areas after putting in bolts (with a slightly incorrect color - urg! Anyone know of a good rattle can match for the 'desert' CUCV paint?)
