PTU aux cooler

[themetalmaster]

Has anyone looked into retrofitting the aux PTU cooler from the 2013+ Performance Package models onto a 2010+ car?

I saw BPD's threads on the aux oil and transmission coolers but didn't see one for PTU.

As someone who just had their PTU explode at 33k miles (yay powertrain warranty!) I'm pretty interested in doing this retrofit.

I think most people are sold on just changing the fluid regularly, but am interested also in the PTU cooler possibility.

I looked into, and it's not really feasible to perform as a retro-fit. Otherwise, trust me, of all people to have considered performing it, it would've been me.

Essentially, IIRC from having looked at the schematics, the PTU Auxiliary cooler is somehow built into the unit itself on the 2013+ model years that have the PP option.

An entire proverbial sh!t ton of work involved. Not to say it's impossible to do, because throw enough money at (any) project, and it can be accomplished. But just not really justifiable cost wise, when as Shodded has already said (and I agree) makes much more sense to just change the fluids out with some degree of regularity / intervals.

I myself am on a "change twice per year" fluid maintenance schedule.

Once in the Spring. Once in the Fall. Hasn't failed me yet.

I am sure it could be done, but it would involve buying 2013 PTU as BDP the cooler is integrated in the PTU. How ever when I get around to install a drain plug in my PTU that will give me the ability to add a oil cooler as the PTU will have a in and out. So some oil lines a cooler and a pump and wallah you have PTU cool. Would be employing virtually the same as a rear dif cooler.

It looked like the cooler was built in from the manual, but I thought I would ask anyway. Its only 300 more than a regular PTU, so I guess if I pay for the next one out of pocket I will upgrade. Assuming it blows up when I still own the car.

I've linked a picture, in case anyone wants to see  what we were talking about.

Cool pic and sounds like the best decision for now until more info comes to light.

Do you have a Key for the number labels in the pic that you could post?  TIA

I'll do you one better and post those pages of the manual.

Way good!  Thanks!

So, it appears it is simply integrated into the cooling system, with the optional "auxillary" cooling, correct?

The Speed6 PTO (what Mazda called it) was provided cooling via cooling system integration. IMO, this should be apart of any design on a performance oriented car. It shouldn't only be optional with the PP variant. Especially with seemingly diminutive oil capacity.

OP, had you serviced the oil in the PTU at any point?

Perhaps the upgrade would be most cost friendly, if transplanted from a wrecked/salvaged PP equipped 13 SHO?

Lest not forget the cost (or the need) to purchase the up sized radiator to proportionally handle the volume of coolant & cool it efficiently

bpd... you've got hood vents.  Do you think they add significant engine cooling? 

I am considering raising the rear center of my hood to create a cowl hood for cooling the engine compartment.

In your opinion could better venting of the engine compartment add enough cooling to obviate the nee for a bigger radiator?

[bpd1151]

I believe it does (help).

I say that because since my cooling fans are programmed to turn on sooner (to compliment 170 thermo) I can feel the heat expelling from the hood vents.

I would imagine that observation is increased 10 fold, once the vehicle is actually moving / being driven.

To what degree it has helped. I truthfully do not know.

Thanks for the input Mike! I was hoping for an answer like that.... even if it ends up costing me $ 

So we need a long term (or at least variations in weather) study telling us simultaneously ambient temp, under hood temp, maybe intake air temp, but definitely with measure of horsepower of some sort in each group of conditions ... one with a stock hood and the other vented somehow with a known cross sectional vent area... then we'd know... I think... how much difference it made in temp and how that affected performance.

What we need is the ford engineers who designed the car to get on the board and work with us on what's the easiest and most cost effective upgrades and mods to perform.... Lol

My PTU had factory fill when it failed. At 33K.

Even if i could find a wrecked PP SHO I don't think I would ever install mechanical parts from a wrecked vehicle.

I wouldn't be paying for labor. I think I could bring my car up to 2013 spec power train wise for around 3K. I usually keep cars for a long time unless I get an opportunity I can't pass up. Its worth it to me.
