Boosting AC coldness and air flow

[theastronaut]

Nothing wrong with electric fans, all new cars use them and they work. I used a HHR fan/shroud combo on my '66 C10 with a temp switch from a Mercury Capri/Ford Festiva in the upper hose that kicks on at 210 and off at 205, with a 195 thermostat. All oem parts and it's been dead reliable. With AC you'd use a trinary switch to kick the fan on whenever the AC is on to pull air through the condenser in traffic.

Finding an OEM fan/shroud that fits your radiator is a better option than aftermarket fans most of the time. Then seal up any gaps so air isn't going around the radiator or condenser. Another option is a separate fan on the condenser itself, but without a shroud so the fan doesn't block air flow through the radiator when driving.
