Default Trying to make a Scott Oil Cooler work

Hello Gents and ladies:

I am beginning the install of the baffle to my RV 7 and I want to use a Scott oil cooler that i sourced at auction. It tests good and is an 8 column cooler.

It is apparently larger than the Vans EA - 11 cooler as it does not fit the Vans oil cooler bracket i bought. I dont see why i cant make it work as many have had to add stiffeners to the Vans baffle kit anyway I thought i could do that and make this coole work.

Any thought on why it wont?

Link to pictures on OneDrive are below.

Thanks for all input.

Dave C,.

Default Difficult

That cooler will be difficult to fit due to the outlet configuration. I have seen it done but due to the outboard outlet and the need to maintain cooler clearance on height of cowling and engine mount it will be tough. I just sold a similar cooler due to those issues.

For me at least, your link requires me to sign in to a Microsoft account, so I am unable to view your pictures.

Dave, you can. BUT, you'll have to space the cooler out from the baffle enough for the block fitting to clear with whatever AN fitting you are using. You might consider sending it to Pacific Oil Cooler, have them clean and test it, and change that block to a MALE AN, or more simply, convert the ends to the Vans Cooler configuration.

It may not be cost effective to do so, against buying the cooler outright from Pacific.

Default Thanks

I have contacted my trusty folks at Alberta Aero and they inform me that they can and will test the cooler prior to install.

|I am a little confused and concerned on TS comments but so far I have the baffle installed on the engine and all looks good so once the cooler is tested I think I will go ahead if it tests good and use it. The fittings seem to be ok but i will install the cowling to make sure that all tucks in nicely.

Thanks to those that responded.

Dave

Dave--looks like the block fitting will hit the baffle especially with an AN Adapter on it.

I think he is fine on that Tom, the cooler has flanges on both sides so he can mount the block facing aft.

You will want to mount that cooler (any cooler) closer to the top/cowl, as the air will flow through the head before it gets to the cooler if it is too low. Make sure there is clearance to the cowl for the outboard fitting, it should be fine for a parallel valve engine. You will need a custom length hose for that side, maybe both sides.

You might want to get the specs on the oil side pressure drop at rated flows as this is a two pass cooler with a low number of plates.

Also, the reason for pacific to have a look is internal cleanliness. The insides have enhanced surface area (turbulators) that easily collect debris.
