<p>Argh. I haven't installed my engine yet. I'm wondering which oil cool I should start with? The one that comes with the engine or should upgrade at install time.</p>

<p>Another cracked cooler! Discovered the crack during my 50 hr engine and prop inspection. This was a 10 row AERO- Classics part # 8000081. I got almost two years of service and 155.2 hrs on it since install. I elected to mount it without rubber isolators to simplify the install and allow for mounting without major cowl work. For some reason I had another one on the shelf and have installed the new one in a similar fashion. I am doing so because I believe the crack may have been initiated…</p>

For some reason I had another one on the shelf and have installed the new one in a similar fashion. I am doing so because I believe the crack may have been initiated by and/or related to the prop and/or engine issues I've had over the past year. The cooler had approx 105 hrs under my old setup and only about 50 hrs with the new prop/crank and overhauled engine. It will be interesting to see if this new setup and cooler are truly compatible. If not, then I will have to explore other options for mounting and/or relocation.</p>

<p>Brian, UL supplier in the USA is Wicks Aircraft. They can get you the bracket, but I'm not so sure it will meet your needs for hanging the non-stock cooler. There will be some fabrication work involved and cowling modification - whether simple trimming/enlargment of the opening to mount the Aero-Classic cooler that some of us have installed.

<p>I am in the process of upgrading my oil cooler to the aero classic. The original cooler is still working but would like to avoid the common leak problem others have experienced. </p>
<p></p>
<p>Is there an after market oil cooler bracket to hold the larger oil cooler in place or does it have to be fabricated? I saw a picture of an adjustable bracket on the ULPower installation guide. Any idea where I can get that bracket?</p>

<p>All,</p>
<p></p>
<p>Installed new cooler with inlet and outlet on bottom of cooler. Now I am wondering about airlocks in the cooler. How has been addressed? How about draining old oil when changing oil?</p>
<p></p>
<p>After last years unscheduled landing I am now up and flying, again!</p>

<p>Later, I upgraded to a 10-row Aero Classics cooler and to gain additional mounting space so the cooler wouldn't touch the cowl, I deleted the rubber shock mounts. I rationalized that since the 6 cylinder Jab was such a smooth, vibration-free engine, they really weren't necessary. It appeared to me that the rubber tubing and longer bolts (the spacing downwards by the longer bolts was necessary to align the 7-row cooler with the cowl opening, but not necessary for the 10-row) provided a pendulum effect that could amplify vibration while solidly bolting the cooler-side mounts against the engine-side mounts would eliminate any amplification. So, to me it appeared to be "six of one and a half dozen of the other." </p>
<p></p>
<p>I kept a careful eye on the mounting, looking for cracks or leaks, but never had a problem and have put on many 100's of hours since then. If the Aero Classic reps made any other recommendations or tips, I'd be glad to hear them!</p>

<p>Greg...I have the 10 row (8000081 non PMA) which I purchased from Ray Lawrence (UL Power rep). It is listed with Aircraft Spruce also. Aircraft Speciality makes some pretty nice high quality hoses for the oil cooler and 750 setup <a href="http://www.aircraftspecialty.com/zenith701750.html" target="_blank" rel="noopener">http://www.aircraftspecialty.com/zenith701750.html</a></p>
<p>Hope this helps and good luck with your project.</p>

<p>Do you know the Part/Model number for your Aero Classic Oil Cooler? Looks like it is a 10 row. But there are two listed. Should I get anything else at the same time? Thanks, Greg</p>
