How do you keep your engine cool in 100+ deg weather? I run a 2002 Blazer ZR2 4.3 Vortec & live S of Houston Texas. It normally runs just shy of 210° w/ a 195° thermostat but, now when towing a small utility trailer it runs up to 220°> A bit too hot for me because it usually runs 200. I don't like that needle on the gauge running past 210 (the 1/2 way mark) 🤟

Electrical fans are maginally more efficient because you can turn them fully off. But the temperature dependent flood clutch means it has variable mechanical draw. And there spinning because of through flow above a specific speed. They just have limited total cfm.

I will also add that the pulley drive ratio of crankshaft to alternator pulleys gives the engine a definitive mechanical advantage in driving a loaded alternator. The resistance on the engine is fractional in comparison to the load for the belt driven standard cooling fan.

@ several racing cars don’t even have an alternator, they rm on battery only. I’m not saying electric funs are not effective, they are, but there is a small power robbed from alternator load. Take a small engine like a 4 cylinder engine and in idle turn on the headlights and you’ll see a drop in rpm due to the alternator load increase due to more electric demand.

Hey, I hope you can help or advise me. I have a Mitsubishi Montero sport 2.5 diesel(also known as shogun, pajero etc), and it overheat in uphills and slow traffic (my city is hot as hell, close to 40°C degrees often). In highway at high speeds it works perfectly. I already checked the whole cooling system (clean radiator, new thermostat, fan clutch is ok, heavy duty coolant, even new cylinder head), but it still overheat. I thought to add an auxiliar fan. However I don't have enough room to add it at the front, because there's a AC condenser and then an oil radiator (or transmission cooler more to the front idk). Do you think if a double straight blade fan would work installed at the front of the oil radiator? I dont know what to do 😑. Greetings from Chile!

You generally don't see any advantage with double-sided fan installs. As the video mentioned, pusher fans have reduced airflow compared to pullers, so you may actually hinder the performance of the puller by adding a pusher to the system.

I run a 19" mechanical flex fan on the engine and a pusher on the front of the radiator. The flex fan normally copes on it's own but with the electric also running it will help keep temps in check in traffic more than just the mechanical on it's own. The electric is rated at 2400CFM and no way it out performs the flex fan and tight fitting shroud, even at idle.

Engine-> direct mechanical energy for the fan Electric fan: Engine->Charging battery through alternator(energy loss)->driving elektric motor(Loss because of internal resistance) -> Electric fan is less fuel efficient "Since they are electric they do not effect your fuel economy" All the energy your car has comes from fuel, unless you regularly use some wall adapter to charge your cars battery. Otherwise where would the enegy being used to drive an electric fan come from, can't be created from nothing. ->Your fuel is used to drive the electric fan

Electrical draw on the charging system translates to far less mechanical draw than a fan. Not only are mechanical fans technically air brakes, but alternator pulleys are usually very small in comparison to the crankshaft pulley, making the mechanical effort to drive them, even under load, minimal.

// "Since they are electric, they don't effect horsepower or fuel economy."// And this false statement comes from Holly. WOW!! Where does Holly think the power (and fuel) comes from to drive the alternator? The shaft to the mechanically driven fan is 100% efficient. The alternator/motor combo required to drive the electrical fans is less than 50% efficient. Now there are many reasons to use an electric fan (including horsepower and fuel economy), but that quoted statement is simply nonsense.

I totally agree, except the shaft to the mechanical fan isn't 100% efficient if it has a fan clutch like most do since the fan clutch will always slip a bit. I think what he might have been thinking is the electric fans save fuel because they only run when needed and don't create any drag when off unlike a mechanical fan that's constantly spinning and taking power whenever the engine is running. But either way, the fact remains that it takes power to move air and that power ultimately comes from the fuel.

100% efficient is incorrect. 100% linear is more accurate. Fan speed increases directly with engine rpm. At idle, belt drive fans are less effective than an e drive fan. Most oem vehicles have an e driven fan.

Sorry but this is highly inaccurate especially coming from holley, alternators on their best day are only about 50% efficient and electric motors are 80-90%. If your fan takes 80 watts of power and its motor is 85% efficient only 68 watts of power is moving air the rest goes up as heat. Also if the fan is using 80 watts of power the alternator is using 160 watts of engine power to power the fan. 160 watts is just over 1/5 of a horsepower so its not much but the wording in the video is just wrong. Electric fans do have an advantage because they only run when needed and at idle can move their full capacity of air. On a side note I have 2 16" fans rated at 80 watts and it takes both to cool my engine (460 bbf aluminum heads cam headers etc etc) on a hot day at idle. Get a good fan shroud youll be happy you did (I didnt lol)
@trumpsextratesticle8590

(160 watts of engine power to power the fan) The alternator is already excited charging the battery, there is no loss adding the electric fan load onto it. So saying the Electric fan robs the engine of power is false, least regarding your comment. The load is already on the engine, an electric fan doesn't "add" load because the alternator has a set load regardless.

The alternator doesn't get "harder to turn" when more load is put on it, so the fans do not rob any more power than what's already being pulled from the engine to turn the alternator (when excited)....

A lot of fake tech in my opinion. To say the mechanical fan is engine driven and the electric is not is nonsense. What do you think is driving your alternator, the wind from your fan? No, as more demand is put on the alternator more strain is put on the alternator, so what you think you gain from removing the fan is replaced by the added load on your alternator. Also the engine driven fan has a clutch that opens when at high speed the air rushing in wants to push the fan faster than the electrons will. This backs off in the alternator circuits and will lead to premature rectified damage. as well as fan wear and tear. It's like having six of one or a half dozen. same thing. Mechanical fans are better, will last longer, and if you correctly match the fan clutch to the radiator It has a thermal property, will perform well for most cars. The thermal sensor on the fan clutch cycles to cutch on and off at idle as needed. Maybe there are some racing situations where the electric fan has an advantage, but for most of us, save your money, buy a new pair of sneakers. Electric fans = more sensors and parts to break down, ( if they have brushes how long will they last?), strain on the electrical system. Mechanical fans = less parts to fail and years long time and true well designed and proven systems. It's your car, you can do whatever you want with it. And anyway, you won't have it long. when the baby comes you'll have to sell it for diapers, so, go ahead, have some fun. Something to chat about at the water cooler. 'Just sayin.............MIke
