External oil cooler on a Type 4

what is the best way to add an external oil cooler on a type 4 motor?

I'm just about to do one on my Double Cab next month. I'm using an off-the-shelf oil cooler unit, but with a combination of custom hard lines and fittings, and a custom made housing with thermo fans under the chassis. I'll be running the full story in issue#15 of VWMA.

You can buy a spin on adaptor that replaces the oil filter as pictured here:

I then ran the "out" line into the remote filter mount, then out of the filter mount up to the cooler:

Then from the cooler back down to the spin-on adaptor:

Obviously this is in my old beetle....but same deal applies in any vw (providing the type IV engine is used).

I have bought a sandwich plate with a thermostat bypass that screws up to the oil filter mount-then you spin the filter onto this plate.I forget the temp the thermostat opens at-it then lets oil to whatever type of cooler you use.I am going to try and fit a sensor in it to switch on a fan.

I got all my stuff from CB performance....however perhaps ask around locally first (eg. Vintage veedub supplies, V-Force, Classic Veedub etc).

Hi

Vintage had some aluminium blocks with a fitting at each end so that oil could pass through and then had a thermo switch in it to turn on the a fan.

I've seen the stock cooler replaced with a block off plate which had fittings in it to take the oil to a cooler, but I think its better to retain the stock cooler as its controlled (covered and uncovered) by the thermostat.

The sandwich plate is neat, but it will make the filter lower, the way Dasdubber did is a good way as well.

I have a take-off plate, Similar to a type 1 style that replaces the stock oil cooler (same as Steve mentions)

My stock oil filter is also blocked off and I run a remote scat unit that has an integrated pressure relief valve.

you can buy the sandwhich plates through any speed shops or repco/bursons etc can order them through Rocket industries.

I run one of the spin on sandwhich plates with the filter bypass blanked off so the oil passes throghy the filter all the time. Mine then ran to a scat cooler with a Davies Craig thermo fan on it.

On a bay window thats lowered with minimual air flow under the car it manages to keep my oil temp on a fairly well modified motor under usual driving conditions under 80 degrees celcuis. In summer on the freeway sitting on 100km/hr it holds the temp to just under 100 degrees. I know guys with the same set up on stock height buses and their oil temp is a bit lower than mine prolly due to a bit more airflow under the car.

FYI I only have a stock type 4 oil pump as well.
