Oil coolers?

[monomer]

I plan on doing a decent sized TD build. Is the Stock cooler gonna handle it? I've been eying a few air-air models, but I see no-one else running them


I know, it does need to get upto temp - I just dont wanna cook anything.

air-air ? Do you really mean air-oil cooler ? I have a water-oil cooler and have had an air-oil.

I think the stocker is about worthless.
I mean I'm sure it does something but it's just to small to do much good.

Many people with tuned TDs have air cores for oil cooling, me included.
Just make sure your adapter plate has a thermostat.

I just installed an oil cooler for my build. Its actually a tranny cooler. picked it up at the local parts place for $20 with the line and such. just mounted it to the front of the radiator. only about 8"l x 5"h x 3/4" t.

Might be a good option for you as well.

What kind, or temp, or what??? Thermostat for the oil cooler. How would you plumb that or is there oil ones or built into the stock one.

This is what they are talking about.  My experience on submarines is that lube oil supply to the bearings should be kept between 180F and 200F.  That temp range is optimal for cooling, pumping, and lubrication.  Any cooler and it's harder to pump the oil through the system and you can have an excessive temperature rise across the bearings and any hotter and you won't remove enough heat from the bearings which risks a wiped bearing.  Trust me when I say that wiping a bearing on a 25K shaft Hp turbine is not fun.  The bearing half shells were about a foot and a half in diameter and about 3 inches thick.

I have a fairly large one i need to find hoses and a way of tapping it into the stock system. I don't want to fuss with removing the stock cooler it seems like a real hassle because of the filter being on there too.
I have a cooler that looks identical to this

without those ends though. The hoses were cut. I have two banjo fittings though for both ends.

Where do you tap into the oil system and do you need pump upgrades or anything to deal with the huge volume increase?

[theman53]

Brilliant. Makes perfect sense to me now. Wonder how to plumb one in though? Some return, pressure sender, out of the head somewhere? Just wondering.

I meant air-oil...




I'm curious as to the plumbing.

You need to eliminate the factory one and get a sandwich adapter to get the fittings needed to run to the cooler.

You can NOT pull it from the head or even from the oil filter mount (top).

It needs to come from between the filter and the mount.

Is it hard to do?

Duane, my cooler needs a solvent bath. It's filled with oil and who knows what all else. I got it for free. I don't even know if it holds oil.
I think i will need a cooler with my build so ...
But hey, if you throw me an offer. I'll let you know if it leaks or not as soon as i test it. Pm me with an offer for it if it were to work.

you can do it without eliminating the factory oil cooler.  it does have its place... it helps to warm up the engine and even out the temps in the motor.  the air/oil cooler will really help with keeping the turbo cool in the summer, but it does need air flow!

what you could do, is use the extra ports on the oil filter flange...

This might give you some ideas... here is the 5 cyl setup with an air/oil cooler:



and here is the 1.6TD oil/coolant setup.

I guess what I was wondering is even with a sandwhich style how do you run the oil. Is it pressured into the cooler? Or is it return from the engine? Or is it just install and hook lines up to the sandwhich and go eat lunch and not worry?
