I'm looking to run an oil cooler on my 02 GT. I've browsed a few things over on C-C.com and random google searches but i'm still kind of guessing on some things.

I'd like to also relocate the oil filter(possibly run two), however, does the placement of the actually cooler effect anything? Obviously it needs to be where air will push through, but does it matter if it's mounted high up on the car(say behind the pony emblem in the front), or down real low behind/near a fog light opening?

When changing oil, is there a need to somehow evacuate the sytem completely, or just drain like normal?

The car isn't overheating or have anything weird going on under the hood. I've just always thought that the cooler you can keep the fluid circulation, the better luck you'll have.

Thanks.

You need to mount the cooler where it will get the greatest possible airflow through it.

It the nose of a Mustang, that's not always easy, especially of you are still running A/C. This is a big reason why I recomend radiators with built-in oil coolers -- you don't have to figure out where to stick the oil cooler.

Drain normally.

You didn't mention it, but I will. Plumb the ENTIRE system using AN fittings and quality braided stainless steel hose. On startup, cold oil pressure spikes can be well over 100psi. Barbed fittings with hose clamps are not reliable enough to deal with this and will eventually fail.

Perfect, certainly book marking this thread. Even answered my "regular hose/hose clamp or braided hose" question before I typed it. ;)

Thanks for the link!

Lastly, are there any drawbacks to a cooler for colder climates(30-40 degrees)? Would a change in oil viscosity be necessary? I think in the Mustangs, it states 5w-20, right? It's 5-something, either 20 or 30.

I have my o/c mounted in the lower opening. I have an sandwich oil filter adapter and got SS lines made with AN fittings.

2 filters are over kill, you will lose a few PSI with the o/c and even more with another filter. I am not a fan of rad/cooler combos because if there is an internal leak you can ruin your engine or at the least ruin your weekend. If a remote cooler leaks, bypass it, done.

That is a concern. But apart from a bad batch of heat exchangers Griffin got years ago, have you seen one fail? (Schwarz's was one of those bad Griffin coolers, right?)

It has been a while bit it still scares me. Also, on a car with a condenser that may run just barely cool enough adding oil heat to the water may put it over the edge. I like being able to keep the system temps seperate.

Invest in an oil thermostat. You do NOT want to run cold oil for prolonged periods of time it greatly increases the amount of wear on the engine.

Invest in an oil thermostat.
But only if you run an oil-to-air heat exchanger. If you run an oil-to-water heat exchanger, the coolant will actually warm up the oil more quickly than if you wern't running a cooler at all! (Coolant warms up more quickly than oil.)

IIRC most quality coolers are going to come with sandwich adapters that are either truly thermostatically controlled at somewhere around 180 degrees or are passively thermostatically controlled, in the sense that their bypass is viscosity-sensitive and will not flow significant volume through the cooler until it's thin enough.

Even better....thanks! I'll admit at first I was looking at the Summit brand oil cooler stuff. After reading this, it looks like in order to do it RIGHT and be durable i'm gonna hafta bust out 200+ dollars. Don't think i'm ready for that, but i've got this thread bookmarked for reference when/if I do.

I am working on getting my Mustang ready for serious track duty. I have a factory cooler in place, but I am curious about results with aftermarket external coolers for the Mustang. What kind of temps were you guys running before the coolers? What are you running after? Are you running synthetic oil? Some of the American Iron guys aren't running an oil cooler. Is maintaining oil temps below 280 a chronic problem without cooling?

I went to the wrecking yard and got a couple of oil cooler setups from 86-89 351W Crown Vic police cars. They are cheap and the coolers are made by Long which make coolers for a lot of other companies. But since you are running a 4.6 with metric threads on the oil filter adapter it may not be worth the trouble.

On a hot day if I pushed the car I would see 300F w/o a cooler. With a cooler (and a better cooling rad) I will see maybe 240F max. I always run Mobil 1 syn.

I was seeing 290, 295 before with an Explorer heat exchanger. Now, with the FRPP unit mounted in front of the rad, it's never higher than 270. I use Redline 15w-50 because of the temps, and the last oil analysis said things were doing very well.

Where are you guys getting your temp readings? Before or after the cooler? From the oil pan or from a return line?

Good info guys. It seems that the 5.0 can definitely use an oil cooler. Any guys with a 4.6 that can share their experiences as well?
