I wouldn't use them together. You'll still have the leaky O-rings on the water-oil cooler. The o-rings loose their seal and dribble oil all over the coolant hoses... Oil soaked rubber hoses suck.

 

Actually, several vehicles have coolers in front of coolers. On the LSVW (Light Support Vehicle, Wheeled) this gets taken to extreme - there's the oil cooler, ATF cooler, and turbo intercooler all in front of the radiator (No A/C as it's a military vehicle) with no measurable adverse affects - plenty of cool air passes between the boundry layer of air cooling the first level of coolers to reach the radiator behind.

At speed there is sufficient high pressure to ram air through 2 levels of radiator, just as 3 core radiators are not noticeably less able to cool coolant than 1 core rads.

At low speeds with only the fan doing the work it's a bit trickier, as the oil cooler in front of the rad has only about 1/4 of it's surface area within the lower part of the fan's sweep area, but @ low speeds and idle the fluids aren't being heated as rapidly.

 

What's the best air-oil cooler to get?

 

i recomend a stock cooler form an earlier model 7. that is just what i like.

Oh oh. I better convert my 83GS and 85GSL. But where do I get the parts? Junkyard?

hopefully you can find one used or on eBay. It's muy expensive new.

 

How about the hoses? I've got an 85 GS and I've noticed that the 79-82 hoses look a little shorter than the 84-85 SE hoses. I'm using the cooler that mounts directly under the radiator, so which should I use so that they will reach?

 

Anyone?

 

If you have an 85, you radiator is too tall and will not allow placement of the oil cooler under it. You will have to mount it slightly in front of the radiator, just like a stock GSL-SE oil cooler.

I am pretty sure you will need the longer GSL-SE style oil cooler hoses, or have some made.

 

Hmm...I'm planning on using a 81 radiator with a 81 oil cooler on my 85 GS, so will I need longer hoses or is everything the same as on the 81 engine?

 

if you change to an 81 core with mounts for the cooler those hose are the same length. cause it is pretty much the same car. one note though if you change to the cooler you have a few things to change like you need the oil filer mount off an 81 engine, some heater hose to reroute a hose, may have to remove ac to get the hose on the front, and alot of tlc.

Well, I got mine from my neighbor. He has a TII and an '86. I have an '83 GSL and '85 GSL-SE. We both had more then enough parts to do it all. If you can find a second gen oil cooler with the oil lines and the cooler still in good condition then I don't see why you can't get it from a junkyard. It's a straight bolt on except for you have to cut through the rad bracket on the side so you can feed the oil lines through. There is a write up or a link to a wirte up floating around here. If you like I can upload some pics?

Thanks jr...

I just got the Haynes manual so this swap should be a snap, if I can get all the parts...DOH!
