How about making the engine warm up quicker and stay warmer longer with no external power usage and a one time cost of less than $40.
Insulating your hood will make warm up times much quicker and reduce the loss of heat under the hood while driving. Saving fuel during cold starts and cold weather driving.
I've run mine for 13 months and have seen no problems and really quick warm ups. I'm at operating temperature within 2 miles from 45F and above. At 32F it takes about 4 miles of city driving.
No overheating unless you are doing all of these simultaneously:
a paper route stop and go, uphill (gravity load on engine), from paper box to paper box (3mph, ie no air flow across radiator) during the summer (95+F ambient temperature) with the
fan disconnected.
Most if not all cars would overheat under those conditions. I just popped the hood, plugged the fan back in and turned on the heat for a minute, pulling the heat off the engine and resumed my task at hand. That was this May, I will unplug it in another week or two as temps drop for the winter.
With the radiator fan plugged in and operating it never goes above operating temps anytime of year under any driving conditions. I unplug my fan about this time of year to save on electricity usage and it keeps my engine warmer, I like to have my engine between 195F and 220F, around April or May I should plug it back in.
Here's the how to:
Insulated hood
I would recommend the insulating for all cars, except those that only do daytime driving in the desert. I'm assuming here.
As for unplugging a fan on a vehicle, you need to know what the safe operating temperature is for your specific vehicle and seriously monitor an unplugged fan as your awareness of engine temperature is the difference between good mpg and a blown head gasket under adverse conditions. Like during heavy traffic, stop light to stoplight driving in the hottest part of the summer. Oh and be the only one who drives that vehicle while it's unplugged.
I take chances so you don't have to.
