Will this most likely seal if I retighten it? Or is it going to be a pain the a$$? Looks like a simple flange fitting and then a copper crush washer? I probably need to crack the two nuts apart to tighten the first one into the cooler, right?

I can't keep cleaning up 12" pools of oil, making a huge mess on the driveway.

It sounds like the dreaded oil cooler leak. Clean it off and I'll be you find a hairline crack in the fitting. I have never had an oil cooler that didn't have a cracked fitting. I had a friend weld up mine.



You will need to find someone who can weld aluminum - and weld it well! They have to clamp it in a vise, cut a shallow groove over the crack, heat the fitting with a torch, TIG weld in the beads, and the best idea is to run a bead all the way around the base and all the way around the end of the fitting to keep it from cracking again. Then they have to grind the end flat again and flush out any metal. It's a job for an experienced aluminum welder, otherwise your threads will be screwed up.

maybe the cooler took a hit by some road debre, and it caused the fitting to warp ever so much giving you a bit of a leak. or it may just need to be cracked then refasten it like you stated above just be carfull it may cost you. if your pockets are alittle light i'd just park it on the grass for now.

Well, I kind of like my grass?? Plus I'm the only one on my block that doesn't park in the yard. I'm trying to set an example, lol!



From what I could see after cleaning it off, both of the washers are leaking. I hit the local Mazda place and got two washers, and a better used bottom line. Mine was soft and squishy in a couple of spots. Anyone know the wrench sizes off hand?? I'd like to do it today, but I spent the better part of the day running errands. Do I need to drain the oil again?? That would suck, since I just changed it three days ago before finding the leak.

What's the best way to clean out the line I bought? My air blower snapped in two after years of faithful service, so I need to pick one up. Mainly I meant what chemical(s) are

safe for the line? The guy where I bought it was saying transmission fluid, but that and rubber don't mix too well. What about a good blast of carb cleaner, followed by an air blower to dry it out?

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.

Buzzbomb

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??,,,,BB







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

willie jspec

Turbo II fits like it belongs and is abit bigger. plus it'll be cheaper than calling the dealer. and road debre is the number one cause of oilcooler leaks. it doesnt take much to crack aluminum especaily at +70 mph. you would think it have more protection huh? but befor you jump the gun just clean it out good and see if you can vacume test it some how if it holds vac then there aint a leak.

Buzzbomb

I also lost probably an ounce or two of oil from both lines? Top one had next to nothing in it. I have seen about 4-5 TII's since they were made. Are their coolers really that available??,,,,BB

willie jspec

hmm try googling turbo II oilcooler see what you get
