Change OEM radiator fan to electric

Has anyone with gen 1, 2.7 ever changed cooling fan to electric style? Was hoping a kit would be available for our gen 1 .2.7 engine. Thanks to all

 

Could be done NP

however the most important component of a puller fan system is a fan shroud….to direct/funnel airflow effectively
I don’t think a E fan zip tied thru rad fins would have any benefits

now if the E fan(s) were bolted to a fabricated fan shroud…….would definitely be better that fan clutch system

 

This alone……nope

 

The above with this would work

 

No pun, but I am a big fan of a factory fan, they move a ton of air and only when needed. I would only go electric only if space was a factor.

 

I don’t know if there’s a ready-made kit specifically for the Gen 1 2.7, but a lot of folks just go with universal electric fan kits and customize the install. It usually helps with better cooling and frees up some engine power since the fan isn’t belt-driven. You might want to check Tacoma forums or Facebook groups-sometimes people share their DIY setups there.

 

The problems I have seen with aftermarket electric fan kits is turning them on and off. Some have a probe that you install in a radiator hose and then you have to do some wiring for the AC and then some have a propritary control box. My unsolicted advice is keep it stock.

Modern vehicles with electric fans work great until they dont... Ram diesel pickups will blow up AC compressors because the fan works part time or not at all, Fords have a set of vents that are electric controlled in addition to multispeed multi fan araingments. Slater could inform us on problems associated with those.

 

Do you have a reason or just because you want too?

 

Maine’s, in hot summer weather, 90+, stopped at red light, or waiting on train crossings, temp will get close to 190 F. It’s tranny temp that concerns me . I have a Hayden tranny cooler but this cools fluid after it reaches 200+. I don’t understand how OEM fan can know when to lock up and provide more cooling.

 

It doesn't free up any HP if the viscous clutch on the OE fan is working. And the draw from a good electric fan uses HP as well, they pull a lot of amps. I have run electric fans for primary cooling on many cars when space demanded, but otherwise I like to run the clutched fan, they work extremely well.

 

Sorry Maineah, spell correction got me!

 

Tmar
190 for engine cool temp is fine
IMO if you get up to 230….need to shut her down
As far as a tranny temp…..I don’t know what is “safe temperature range “

assuming you have a automatic transmission?
Stand alone transmission cooler?

 

My 3RZ sits at 185 on the scangauge FWIW. Manual. Seen it hit 190 on occasion with the AC on.

 

You are good to go with those temps. Normal operating temp for sure.

 

You need this dual electric fan mfg'd by Flexalite . It has dual 11" diameter fans that will push 2500cfm thru your radiator . This style fan actually is made for toyota trucks

This fan is what I'm using on my 72 Camaro that has a 600hp sbc and keeps coolant temp at 185deg on hot muggy summer days in Middle tn

 

Fan clutch will push more cfm than an electrical. The clutch thermo-coil receives heat from the radiator, once it reaches a predetermined temp, the coil will lock the clutch to engage the fan.
