it should fit. but dont buy with out seeing if your fits the car your getting it from. you'd be serprised at how many parts you could swap. from clutches to trannys alot is compatible. come on get grassroots style on it

I am just wondering if the lines fit, and are at the right angles, etc. I can make brackets;),,,,BB

Yes you will need to drain the oil again unless you plan on wearing it.IF I can remember off the top of my head they are a 17 and 19mm for the lines.Been a long time since I had a stock oil cooler.I still have yet to see one that is cracked in that so called common place.Oil coolers around here seem to stay intact.
They get cracked from overtightening. When you work on the oil cooler lines, remember that the cooler is aluminum and cracks easily.

I think I just found the crack in that common place. This looks like a microscopic dark line. Ordinarily that wouldn't bother me, but it seems to turn the "corner" towards the threads. So, I guess there goes another wad of money repairing it. I can only imagine what new one costs, and it will only crack the same way later on. How much do you think this would be to repair??
That's probably it. The crack is usually difficult to see, and sometimes you can barely catch a pick on it. You might try taking it to some place that welds a lot of aluminum. One of the world's best boat propeller repair shops is near here and I think I might try taking my next oil cooler to them. It sure beats the new oil cooler price: http://www.mazdatrix.com/getprice.as...m=14-700A-8871

Turbo II fits like it belongs and is abit bigger.

Wrong. It should be a simple swap into a GSL-SE, but the early oil coolers have different brackets. Your sidebar says your car is an '82? You'll have to fab up brackets to put in a later oil cooler.

Yeah, I saw that price. It's why I was asking about tthe 87, there's one at the local pick your part. are the lines in the same location, with the same size fittings? If they're angled

real steep or something, I'm not sure about it.,,,BB

dude i got a turbo II oil cooler fabing the brackets are easy tho, if your handy i guess

Just get the hairline crack(s) welded. I just got 2 cracks welded at a local machine shop. I paid $32 and it has completely sealed the cracks. Before I was dumping around 1 quart every 100-150 miles and had huge oil spots under the car. So far I haven't had any problems after 1000 miles and its alot cheaper than buying a used or new oil cooler. Check out Dave Disney's site. http://www.rx7.voodoobox.net/index.html

Look under the How-To's and then oil cooler fix.

Buzzbomb 06-07-2006 10:37 PM

Thanks. I'll probably end up doing that. The local place just got me for $45 for the lower hose, used. It's in better shape than mine at least. My top line is rusty but in great shape. Yes, the whole end of the cooler on that side is caked with oil and dirt. I vaguely remember it making a drip or two, but nothing like now. Tomorrow is reserved for fishing, but Friday or Saturday I'll yank it out, and pressure wash it and blow it out. ,,,,BB

If you're not running a stock cooler, then what're you using??

I am running a Hayden Heavy duty cooler I does the job nicely.The look on the guy's face when I ordered one for my old 83 was like....... https://www.nopistons.com/forums/pub...IR#>/blink.png He doesn't know how hot these engines run. https://www.nopistons.com/forums/pub...1047683785.gif

Ouch! You can take your old, leaky hose to a hose supply company and have a new hose made from the fittings for less than that. AFAIK the fittings are the same between the early and later coolers, and although the fitting locations are a different they should still hook up. Please remember, I've never had a 2nd gen cooler, and my GSL-SE's cooler has been sitting on the shelf a few years, so I could be a little off about the fitting locations.
