This evening I was looking under the hood of my 1993 Camry LE with the 3VZFE V6, just under the front bumper, positioned inward but outside of the radiator is a long curverd line with cooling fins on four parts of it. One line runs in from the passenger side lower right front Quarter, & it runs continuous & exits out the same way???? I know that it is a cooler, but for what????.....:headbang:

Your car is equipped with hydraulic cooling fans, yes? Its linked to the power steering reservoir which is linked to the engine cooling fans. :thumbsup:

Your absolutely correct! It is equiped with the Hydraulic cooling fan! Do the power steering unit & Hydraulic Fan share the same fluid?

I once had a car that with hydraulic windshield wipers, what a stupid idea. :facepalm:

But even more stupid was that the Air Conditioner and the power windows were on the same circuit. So when the Air conditioner went out, the power windows did too, and I couldn't roll them down, OR use the Air conditioner. :confused:

I had to drive around with the door partially open, since it happened in the summer time !!. It was a real monkey drill making right turns. I had to hold the door to keep it from flying open, at the same time turning the steering wheel with the other hand. And if it weren't for the seat belt, I would have ended up on the street.

WTF are these people thinking when they design these dumb ass systems.

OK, I'm feeling much better now......;)

thats the tranny cooler. you could post a pic to be sure but IIRC, all gen3 V6s were equipt with a tranny cooler positioned exactly how you described. the lines snake around the radiator and connect to the tranny just behind the radiator.

EDIT: this is what your referring to yes?

i thought that was the power steering fluid cooler... at least on my car the lines goes to the PS reservoir

^ it is, but the power steering fluid and pump also drives the hydraulic fan

yeah i knew the fan operated on the PS circuit.. its just that i was confused as bigbird said it was a tranny cooler witch is, i think, located inside the rad

oh ok so i was mistaken, then king...where the heck is the tranny cooler? theres nothing in the haynes manual. and glad i know that now, the new cooler goes on next weekend
follow the lines fron the front of your trans... you should track them down to the passenger side of the rad

Rob- you're pretty close as it is! That rusty thing that loops from the passenger side and then back to the same side is for the power steering fluid. The tranny cooler is actually built INTO the bottom of the radiator. It goes in pretty much one side of the rad, and then back out the other (kind of). It's hidden and can't be seen from the front of the car.

As lemegacool said, it'll become more obvious when you track the hoses coming out of the tranny on the driver's side, just left of the battery and from under where the cruise control unit is

It should be noted that the power steering pump and the engines hydraulic cooling fans although united by the reservoir and a common pump drive shaft are two SEPARATE PUMPS with different pressures, and different relief valves ect. . . .

What cracks me up is the engine cooling fans, have to run that cooler to cool the cooler! :eek: Not quite as bad as windows and AC failing all at once tho!

Here's what's inside a typical engine radiator to heat and cool the automatic transmission; water to oil heat exchanger. . . .

As King said, all you see are the fittings.

Interesting. So I guess theres ZERO (to very very minimal) parasitic loss from the engine to drive the hydraulic fans versus if they were electric fans? Just playing with the idea of an electric fan swap for a 3vz in my head.

Rob,
For the sake of the tranny, run the new cooler in series but after the existing cooler in the radiator. The reason is the engine comes up to temp sooner than the trans and the trans will last longer if its brought up to temp sooner. In the race world "who cares", but a daily driver = yes!

Also, take the time to mount the new cooler with something other than the pull ties which hang it on your condenser (assuming you have A/C yes). Time and vibrations can damage the condenser so use some metal strapping and nylock stainless bolts/nuts.

Here's a good place for another tip:
Barbed fittings with hose clamps work well for keeping rubber hoses on. The problem is when we make custom metal pipes to connect accessories we end up with tubing with no quick way to connect rubber hoses. Here is a solution:

Take a 5/16 or 3/8" steel brake line tubing and form it to fit the application.
With a brass union coupler and some RED Loctite, apply Loctite to the end of the tubing.
Slide the nut, the ferrel, and the union onto the tubing.
Tighten the union tight enough to collapse the ferrel onto the tube displacing the Loctite. Remove the union and the nut. You tubing now has a rounded hose-barb that keeps the hose from blowing off. This is much better than doing NOTHING and hoping the hose never blows off the tubing.


This is nylon tubing but the principal is the same. Steel does not use the insert in the core of the tube so disregard that. Slide your rubber hose over the brass and secure it with a hose clamp. Done!

I don't know if I'd say that. If theres no loss, than why does it need a cooler? :lol: :lol: :lol: If it makes BTU's to be shed, its wasting engine power!!!

All I can say is I'm glad mine is electric for the weight savings and BS that hydraulic system adds. Plus I'm not cursing and swearing like Rusty9 is right now! :thumbsup:

ok cool, now i knwo where to look:thumbsup:.

thanks for the advice, i have read about keeping the stock one in place before but didnt see how it was possible with it mounted in the front:rolleyes:...obviously, not the case. ill keep this all in mind when i go to install it.

Defeat! I can't figure out which port on the trans is OUT to cooler (hot) vs IN to trans (cool)! TSM says nothing. I guess you can go brail and use your hand as a temp gauge???? This could be misleading depending on when you do it.

Guarantee if you hold it at stall RPM for a couple minutes (power brake :ugh3:) and then grab the lines you'll know which one is OUT! :lol: :lol: :lol:

Just don't slide a hose onto a straight piece of tubing. You'll be walking when the trans dumps all its fluid one night :facepalm:
