    I'm sure it's been talked about but search function returns "trans cooling" subjects.


    Is there an electric cooling fan swap out we can do or are we stuck with the direct drive fan?


    Does anyone know the CFM our factory fan pushes?

    I believe there is a TSB that adds an Electric Fan in addition to the normal fan to improve AC performance.

    You can add an electrical fan...you would need a “puller style” with ac relay. Measure your existing fan shroud get that size or slightly smaller. I plan on doing this just haven’t gotten around to it yet. Jegs, Summit, EBay or Amazon would have one just no direct bolt in plug and play replacements that I’m aware of at this time. Probably pick up a few ponies and engine will rev quicker with less parasitic drag.

    I'm tired of hearing the fan rev up so quick, it seems as if the motor is straining.

    It is straining, but it's reliable. I changed lots of fan clutches on domestics but have yet to on any 96+ Toyota.

    The problem is you mess with engineering, the shroud is designed with a mechanical pull fan in mind. The direct drive fan is ideal because it speeds up with engine load, something that an electric fan can do, but adds complexity.

    I would never delete a mechanical fan unless there was a fail safe designed to alert me of failure.

    The mechanical fan is better than any electric fan you could fab up. You can really hear your fan? I can't hear mine.

    I have a manual trans and I actually like the noise of the fan when I rev up.. it reminds me of the sound of the old fj60 and fj70 with in-line 6.

    It makes me feel that I am in an older truck.. or just connected to the older models.. heritage feeling..

    It might sound like BS but is how I feel...

    Another reason I love my TOYOTA truck. It might be induced by movies like back to the future or toy story (I’m 31 YO) but anyways, I like it.

    I guess I'm not revving enough :(

    I want to add a electric fan to increase airflow across the a/c condenser when the truck is not moving and the rpms of the clutch fan are low.

    It's a valid question...anything to take less drag off this engine the better.

    I know when I put the AC on, it feels like I drop from a V6 to a 4 cylinder power wise.

    My fan clutch went out on my '96 Tacoma at around 210k miles. Lasted a long time. One cold morning I realized my engine was abnormally quiet at start up haha At least they are very easy to change out.

    Look at other Toyota/Lexus vehicles for design ideas and capacities. The fans from a Sienna w/ the 2GR-FKS might be enough. Up the efficiency of the system with degas/expansion tank. Might want a larger alternator and battery to keep up with energy demands.

    Switching to an electric radiator fan will do nothing for this. The drag you're feeling is from the horsepower used to turn the A/C compressor.

    This truck does not use a mechanical direct drive fan. It uses a viscous fan clutch that is setup to provide sufficient cooling. It will not turn on until the clutch assembly heats up to 210-220°F.

    Correct. I was using the A/C as an example of another parasitic drag on the engine and how much of a difference it is if it's there or not. So removing the clutch fan would be like turning the A/C off kind of difference right?

    The viscous fan clutch is one of the best and reliable methods to cool the radiator and use the least HP possible.

    The fan clutch goes full blast when it hits probably 210-220°F. Below those temps, the fan is basically freewheeling but they can be setup to come on sooner at lower temps, or too have a little more drag at idle and colder temps.
