How hot should engine be allowed to get? Electric Fan Install

edit...
didn't all these motors have a belt driven fan ( spinning all the time the motor is turning)...

 

Of course they did & your point is???

Ceptin' for some of the FWD stuff that came out in the later '70s, AFAIK all US built autos in that time period used a belt driven fan... The shift to electric fans began in the '80s...

 

My 91 F150 has a belt driven fan.

 

By the late '60s, belt-driven fans either had a clutch or flexible blades, which rendered them virtually inoperative at higher RPM and speeds.

 

did Mav/Comets have clutch fans?

 

that's my point, these cars came with belt driven fans and T-stats from 160-190...
so the temp the E-fan comes on at should be the same...when the engine is cranked...

 

Nope, most of the reason for going to electric fans is they don't run unless needed for cooling... Excepting for using A/C, the electric should never be operating before engine is at approx 205-210*(I'm referring to a factory application)...

BTW just because the Master Parts Catalog lists a 160* stat, I'm not believing one was used in any factory application beyond mid '50s(exception boats or possibly stationary/industrial engines)... Back when they were used in automotive applications with Alcohol antifreeze as boiling point is lower than water... When Glycol based coolant was introduced stat usage jumped to the 180* and by mid/late '60s, temp increased to 195*...

 

No, but other American cars did. My '73 has a factory 7-blade flex fan.

 

I thought this thread was about a Maverick...

 

were we not talking about a 70s Maverick(no factory E-fan)...

 

Frank, when you can figure out what you are talking about, let the rest of us know...

I explained E-fan operation, makes no difference what vehicle it's used on...

 

It is, and I stated what Mavericks had.
Point being that even though the belt-driven fan isn't turned on & off by a switch or thermostat, it is not really functional at all times on cars this era. Either the blades flatten out at higher speed/RPM, or the fan freewheels on a clutch.
In other words, there's no reason for a fan to pull air at all times. Just at low speeds or at temps over a predetermined value.

 

An e-fan is all about increasing efficiency and reducing wear and tear on the engines front accessory drive/s. Having it run any time other than when the motor is actually hot enough to need it is just being silly.

An e-fan with properly set t-stat can also help engine lifespan as well because it allows faster warmups and can help reduce heat soaking at shutdown. Heavy amounts of heat soak is hard on gaskets(causes squirm and excessive crush), loosens bolts(greater degree spreads in thermal cycling), and can even start to coke oil in extreme heat affected climates.

 

why is this so hard for you to understand? I'm talking about...the stock fan/T-stat setup Ford designed for a 70s Maverick. why wouldn't you want to match the temps that Ford designed?
it was designed to run a fan at startup (belt driven).
emissions had a lot to do with the faster warmup...(clutch fan)

 

Well Frank I can see you really don't have a clue about cooling system efficiency... The stock MAVERICK belt driven fan that operated continually was just making unnecessary noise and wasting energy... As already pointed out, the electrics can be turned on only when needed...
