Many of the carbed units suffered vapor lock. This happens when cooler gas from the tank, enters a very hot carb on a hot day. GM supplied these retrofit fans to reduce
carb. overtemp. My 86' Iroc (which is carbed) does not have one, so I do not know the cycle time befor turn-off. Check with any GM dealer. Matt

Re: fan wont turn off for an hour or 2 after car is off
Old post, but I was working on this, so I thought I would add what I found. My car has everything but the hose from the fan to the carburetor.
HARD START,SURGE/HESITATION HOT FUEL HANDLING PROCEDURE #86-650-101 - (Mar 17, 1986)
VEHICLES AFFECTED: 1983-85 'F' Car With L69 Engines (Engine Code G) and 1983 - Early '86 'F' Cars With LG4 Engines (Engine Code H)
Customer comments of vehicle surge, hesitation, and/or stumbles after the vehicle has reached operating temperature, then parked and restarted, (Hot Soak) may be received. This condition is caused by a large temperature difference between the carburetor fuel bowl and the fuel delivered from the fuel tank. This condition can be eliminated by the installation of an auxiliary blower fan, which reduces the temperature of the fuel bowl during a hot soak. The fan is designed to operate at an engine coolant temperature of 106 DEG C (220 DEG F) and stay operational until the coolant reaches 90 DEG C (195 DEG F). This will maintain a fuel bowl temperature of approximately 74 DEG C (165 DEG F).
Listed below are Hot Fuel Handling service kit part numbers:
P/N Usage --- ----- 14094394 Chevrolet 'F' Cars
14094395 Pontiac 'F' Cars
NOTICE TO DEALER: In each kit there is a one page flyer explaining the blower kit operation. Please insure that the customer receives this flyer.
