External Oil Cooler 2.0L Air Cooled

Looking for info on external oil coolers for a very heavy 2.0l vanagon.

On the water cooled engines there is enough room to add a sandwich adapter with oil line ports between the oil filter and engine. The air cooled engine is a lot tighter in that area. You might look at installing a remote oil filter and cooler. You can find spin on adapters that replace the filter. It looks like you are not in the US. I use a company called Summit Racing and Pegasus Auto Racing. They will have what you need. You would be fabricating the mounting and lines.

Here is the down side. You are adding multiple points of failure that will result in a seized engine. I saw your other thread regarding oil temp. My suggestion would be to run a thinner synthetic oil. Not Mobile 1 unless you run Mobile 1 racing. Higher viscosity oil creates friction and that is more heat. I ran Mobile 1 20-50 in my VW race car. I was seeing 260F. Switching to Redline 30wt dropped temps 40 degrees F. No other changes.

Hey everyone, I've been following several posts across various sources on temperature control on air-cooled engines. At the risk of oversimplification (a place my simple mind likes to go) and a minor hijack of the thread, for us air-cooled Vanagon owners, is the solution to keeping your type IV motor from overheating possible via:

1) Making sure the factory air cooling components are working as intended
2) Using the right viscosity oil (I'm seeing 5W-30 synthetic in these posts)
3) Installing temp monitoring to keep an eye on things

Or are there additional steps that one should (not just 'could', but really 'should') take to ensure the longevity of the motor when heat is concerned?
