Just installed the Cool-Collar oil filter heat sink. Checked oil temp on dip stick with IR thermometer before and after installation (engine at normal operating temp).
Oil temp before install(10 mi. driving) - 214 F
Oil temp after install (10 mi. driving) - 197 F

17 degree drop in oil temp for - $18.95 from jcwhitney.com - not bad.

 

more details please. does that go around the filter? i have never seen or heard what it is.

 

It's a finned, aluminum collar that fits over the oil filter and is secured with a stainless steel clamp. I had to trim off 1 finn width to fit the Motorcraft FL-400S filter - but it was no problem.
Fits perfectly and it even protects the filter from stones, etc. For $19 bucks and shipping it's a cheap mod that actually helps cool the engine oil down. And it looks cool, too!

Here is the link to J.C. Whitney's catalog page.
There are a lot of articles about this product on the net. Do a search on "Cool-Collar" if you want to read more about it.

Here some more info on the Cool-Collar install and the manufacturer's test data.

ordered one ;D

 

Talleywacker,

When you get it you'll need to cut off one fin to get a perfect fit on the Motorcraft filter. If you use a filter with a slightly larger diameter (like Mobil 1) no trimming is required. The instructions said it was scored to easily remove 2 fins, but I couldn't see the scores so I used a hacksaw. Aluminum is soft so it was no big effort.

 

How does this affect your oil system when your car isn't up to operating temp and it's cold outside? Wouldn't this cause oil to flow poorly through your filter?

 

Thanks for the info F150Forever. I use Mobil 1 filters so I would imagine there would be no need to modify.

I am also eyeballing the dual filter system you can buy from them for $54... anybody ever try this ? What about that magnetic thing that straps onto the filter?...

 

The heat transfer is not fast enough to affect the oil in the filter. All the oil in the engine flows through the filter in about a minute so it wouldn't spend enough time in the filter to cause that portion of oil in the filter to be much different (if any) from the rest. The cooling is averaged over the entire oil.

My $0.02

 

looks like another one to add to the truck. for 20 bucks what could it hurt

 

how does that tiny thing cause the 17 degree drop then? (i'm not trying to be a pain, just curious)

I'll probably get one of these bad boys if they don't cause any problems.

 

It works the same way a remote oil cooler works, but obvioulsy not to the same extent. The heat sink works the same as those used in electronics to cool hot devices in stereo, computers, power supplies, etc. Another factor is the air flow over the heat sink fins while on (or off) the road.
You have to read the supporting articles and then make up your own mind. All I can say is that it showed the 17 degree decrease on my engine.

talleywacker,



A friend of mine actually put a magnet in his oil pan. When I asked him what that was about he said it would catch any small metal fragments floating in the oil causing less scratches. It makes sence.

 

.. but there's a major temp drop inside the oil filter, doesn't that affect it's operation?

 

No, there's not a major temp drop in the oil filter. The oil is continuously flowing through the filter with some heat being removed as it passes through. The overall effect is a drop in temperature for all the oil. It doesn't get cold in the filter and then get dumped back to the supply. The heat transfer takes place as the oil circulates. It's just like your radiator - the cooling is spread out over the entire coolant (it's an average since it's moving). That's the best I can explain it.
