SPAL 30102049 16-Inch High Performance Curved Blade Cooling Fan - Black - Perfect for Automotive, Marine & Industrial Cooling Systems

My 76 Dodge truck with a 360 V/8 began overheating during the Texas summer and during prolonged idling. The temp would climb to 230. I replaced the engine driven fan with a 16 inch, electric puller fan, that I purchased online for $40.00. The "cheapo" fan was advertised at 2475 CFM . It helped a little; however, the temp would still climb to 220 when idling. I swapped my factory replacement brass radiator for a four-core aluminum radiator and it made no difference. I installed the Spal fan (with a true CFM rating of 2020) and now my truck runs between 185 to 190 and it can idle all day.The fan is kind of loud when you standing outside the truck. Not so bad with the motor running or inside the cab. When the fan starts it draws about 20 amps; however, it runs at about 10 amp or a little less. I used a 30 amp fuse and a good relay.The A/C is also much colder.All in all don't trust the cheap fans.
