Oil Cooling. External oil Coolers and how-to's

[kennethdlt]

Hey guys I haven't had much success looking for a thread on external oil coolers. I would love to have any advice or build threads on what anyone has done to keep an extra edge on a big hot engine. What external oil coolers are recommended for a 71 Ghia. I have a 1914cc with dual 40s and it's making lots of heat. Thanks!

I run a Setrab from Jon at air cooled.net and have been pleased. Compact, quiet and a nice piece. Should also run a thermostatically controlled sandwich adapter at the oil filter. It diverts colder oil away from the cooler until needed ( 180 degrees)

You are full flowed, yes?

You need to address what is causing the heat and not just patch it with a Band-Aid (oil cooler). I'll guess 80% of the people that put them on their cars do not need them. Tell us more about your engine. What oil are you using? How hot is the oil getting and how hot do you think it should be?

I run a 2276 in my Ghia and I do not have an auxillary oil cooler.

I agree with Dave. Mine doesn't need it and it's a 2332 mild compression by today's hot street standards. If you do put the aux cooler on, get the thermo plate diverter though. My engine struggled to warm up with just the setrab in the loop as it would pull heat away I was trying to build on warm up cycle.
I got it, glad I did. Needed? Probably not.

Interesting comment on need.... Summers here runs anywhere from 95° to 105° daily, and last few time out motor has been HOT, heat radiating off it is terrific after shut down... Guess first thing would be to get good temperature measurement of oil.... Had not thought about adding a cooler until mentioned now...

In 1976 I built up a 1600cc SP engine into an 1835cc DP engine. I didn't have doghouse cooler, this was going into my 1970 sedan, and I had dealer-installed AC, and Arizona heat to deal with. Doghouse stuff was expensive then, and I wanted to add an oil filter to this engine, and read in Hot VWs magazine about fan shroud mounted external oil cooler to get the stock oil cooler out of the fan shroud (I was really cooking #3 and #4, could tell by how fast the spark plug seals hardened).

So I still have this set-up, still on my 1835cc engine. Note that this arrangement is frowned upon by many on The Samba, so I'm not pushing for it, just relaying what has worked for me. However, in ensuing years I removed the oil filter part and went to a Maxi2 pump/filter, to free up more room in engine compartment and not have to use aluminum foil "dams" to prevent oil leakage during filter changes.

A small Mocal cooler and fan on my 2161 made the difference between (borderline) too hot on a 95º day and fine. I had all the tin, good tune, good air supply, stock doghouse, but on a 95º day temps would hit 225-230 and I couldn't live with that. The cooler is small (6"x10") and the fan only runs on a hard pull, or extended sitting in traffic. No more worry
