Where to put external oil cooler??

[Mike70gtx]

Put in new f-body radiator and already have a small 3/4 inch B&M Cooler for the trans. I put it between the radiator and my Cas v2 front mount. I got a new B&M cooler like suggested on one of the threads, but it's 1 1/2 inches thick and won't fit between the rad and front mount. So should I:
A. Get a thinner cooler.
B. Put oil cooler ahead of the Cas?
C. Mount the cooler on my dual spal fans, on the motor side?
It actually looks like "C" could work, it would center it between the two fans and the four corners would mount to the outer cross bars of the fan supports.
Does anyone else have this set-up or have an good ideas.
Thanks

I eventually rolled the dice and went without an oilcooler. Turns out that since the car never gets over 167 on the coolant gauge an oil cooler is not needed. The Fbody does a good job, but I have a powerstroke intercooler which im sure isnt as thick as ur Cas. Try it out and see where ur at before u spend the money.

I don't understand the connection between these two. Oil temp and coolant temp are different- just because one is high or low, that doesn't mean that the other is the same. Now maybe you don't need an oil cooler, for one reason or another. But not using one because coolant temp is low is like not getting one because the car is white.

Mount the tranny cooler and the oil cooler in front of the AC condenser (which should still be) in front of the F-Body radiator...
run all the lines around and under the cap end of the radiator...

I guess I would have the same question then. Is it posible to have 160deg coolant and also have 210deg oil temps???

And if Im wrong I would not be offended in any way but I feel if the overall operating temperature(coolant) is really hot then the oil will break down sooner, I know that to be fact cuz I once drove my first car ---a 76 olds cutlass without antifreeze in it until it started knocking and siezed up. shockingly after cooling down it started up again but I had to add water and oil cuz the oil had burned right up in the motor. The car never burned oil before that incident.

I don't have enough room between that and the front mount intercooler. I have enough for a 3/4 inch cooler (which is my tranny one) But my new oil cooler which is 1 1/2 is too thick.

I have been wondering if there is any bad reason about mounting a cooler to the sway bar - the front mount leaves lots of room around the bar.

I mounted mine behind the RF air dam. With the air dam reinstalled, you can't even see it. The trans oil cooler is right above it and has air drawn thru it via the fan also.
I just made new oil lines using steel braided hose...

[Mike70gtx]

SWEET! I don't have the fan style cooler. I could sent this one back. Do you have the part numbers for the braided hoses and connections? Are they very hard to put together? I definitely like the look.

[yullose]

The hose is just -08 steel braided line. The fittings at the adapter are 1/2"-pipe to -08 90's. The lines have a straight -08 hose end at the adapter and 90* hose ends at the cooler. The cooler came from Summit and already had the male -08 ends on it. It was a very simple installation, other than having to weld the rear bracket to the frame. The front mounts right to the lower lip of the front bumper. I can get a part number for the cooler if you want. Anything bigger won't fit in that small area.

I would think so. Since the coolant flows inside the block and heads, in the water passages, and the oil flows through the oil galleries, through the crank, through the bearings, and splashes on the cylinder walls and on the pistons, the two cooling systems are pretty much independent. Oil picks up heat from one group of components, coolant picks up heat from another. Maybe if there was an oil temp gauge to check on the oil, it would be Ok. But GM likes oil coolers, as do most other auto manufacturers. Just seems sensible to keep it.

Another very BAD place the oil travels is to the oil super-heater...

Some like to call it a "Turbo".
(Don't mean for that to sound smarta$$...just being funny)

For the few days I ran my car without the cooler, the oil got watery thin due to excessive heat and the motor never went over 170.
The oil started to break down and darken very quickly... Since I hung the cooler under it, the oil still looks like it came out of the bottle.
Oil pressure also increased as a result of thicker viscosity via cooler oil.
